Developing akoya pearl culture on the Australian east coast, challenges and constraints.
Authors: O'Connor Wayne , Heasman Michael P. 
Published: April 2021

Abstract

Developing aquaculture in increasingly urbanized societies poses significant challenges. An example has been the recent attempt to establish a pearl industry in the sub-tropical waters of New South Wales (NSW) on the Australian east coast. NSW is Australia's most populous state with the vast majority of the population and development occurring along its coast. This development has led to conflict over land and water use. In 1993, interest began in developing a marine pearl industry using the native pearl oyster Pinctada imbricata. The NSW Government was approached and research was undertaken to establish the status of the P. imbricata population in NSW, its amenity to culture, its capacity to produce high quality pearls and the likely impacts that a pearl industry might have. In 2001 the first application to establish a 92 ha commercial farm was made, which met with considerable local public opposition. Concerns regarding the social, economic and environmental impact were raised and the government responded by establishing an independent Commission of Inquiry. While the Commission recommended that, with certain constraints, the farm could proceed, the government ultimately overturned the decision citing environmental concerns and refused the development application. A subsequent, significantly altered application was lodged in late 2003, but this application also met with local opposition and was similarly refused in mid-2004. Despite research confirming the environmentally benign nature of the proposal and the confirmation of economic viability, the failure to initially effectively allay public concerns ultimately prevented the acceptance these two applications. The future of a pearl industry in NSW is now unclear.
Development of low-cost marine fish cages in northern central Vietnam.
Authors: Nhu Van Can Van Can 
Published: April 2021

Abstract

Research on cages for marine aquaculture in the northern central region of Vietnam has led to the introduction of two low-cost cages (LG-60 and BG-210) constructed from small floats, nets, rope and anchors, and an improved wooden raft (LC-160) modified from locally-made cages. The hexagonal LG-60 and octagonal BG-210 are cheap and highly flexible, while the improved wooden raft (LC-160) constructed from four hexagonal units has strong construction and is appropriate for family-scale production. The new designs are strengthened with a dynamic mooring system, which can absorb much of the kinetic energy of the rapidly changing forces that the cage is subjected to during severe conditions. These cages have performed well in the harsh conditions of the northern central coast and have survived the monsoon. This research shows that there is an opportunity for mariculture development even in exposed areas.
Culture-based fisheries - oxbow lakes.
Authors: Rahman Md. 
Published: April 2021

Abstract

Oxbow lakes or baors are a major resource for culture-based fisheries in Bangladesh. Most of the oxbow lakes are situated in the southwest part of the country, mainly in the five districts of Chuadunga, Faridpur, Jessore, Jhenaidah and Kushtia. Traditionally fishers catch wild fish from the lakes. After implementation of the second Oxbow Lake Project (OLPII), fish yields increased tremendously through culture-based fisheries management. Current yields in oxbow lakes average 760 kg ha-1 year-1, while some lakes produce 1,800 kg ha-1 year-1 (Ramboll, 1998; Ahmed et al., 2003). The oxbow lakes are managed through organized Lake Fishing Teams (LFTs) and Fish Farmer Groups (FFGs), both of them raising fish in oxbow lakes and in so-called "baor fish ponds". Fish production has been increased 3-10 times compared to pre-OLPII intervention with institutionalized fisheries management. The LFTs and FFGs manage the lake properly. Fingerlings are stocked to increase fish production and provide income from the culture-based fisheries. In the baors, 86% of FFG members were female and 67% of women participated in fisheries-related activities.
Carp polyculture in ponds in greater Mymensingh, Bangladesh.
Authors: Colavito Luke 
Published: April 2021

Abstract

The greater Mymensingh area comprises seven districts and a population of over 17 million people (2002). This area was the location of DANIDA's Mymensingh Aquaculture Extension Project (MAEP) implemented jointly with the Government of Bangladesh (GOB) to assess the potential of aquaculture to alleviate poverty. The MAEP (1989-2003) promoted carp polyculture through the development of hatcheries, nurseries, micro-credit, and an extensive training programme targeted at the poorest households. The MAEP played a key role in initiating improved aquaculture practice in Bangladesh. Winrock International was engaged by DANIDA to document the impact of the MAEP. In the Mymensingh area, over 1.4 million households have adopted carp polyculture. Annual income per household from carp polyculture is US$ 145 (2002). Unit yields increased from 1 to 3.3 t ha-1 from 1989 to 2002. Total production has increased from 85,000 to 351,000 t resulting in an annual increase in revenue of US$ 204 million. Over 40% of Bangladesh's aquaculture production now comes from greater Mymensingh, which has less than 10% of the nation's population. The Internal Rate of Return (IRR) for the MAEP investment is 224% and the cost benefit ratio is 1:27. The MAEP has had a profound impact in improving the lives of the rural poor.
Cage culture of lobsters, Vietnam.
Authors: Le Anh Tuan 
Published: April 2021

Abstract

Cage culture of lobsters started in Vietnam in 1992 in Khanh Hoa province. Since 2000, there has been significant expansion in lobster culture in southern central Vietnam from Da Nang City to Binh Thuan province. Ornate or spiny rock lobster (Panulirus ornatus) is the most important cultured species but P. hormarus, P. longipes and P. stimpsoni are also cultured. There are approximately 33,000 grow-out cages of which 17,000 are located in the coastal waters of Khanh Hoa province. These marine cages produce approximately 1,500 t of lobsters with a farm gate value of more than US$40 million in 2003. This case study reviews the current status of cage culture of lobsters, and identifies major technical and socio-economic constraints to further development.
Artificial seed production of Pangasiid catfish in the Mekong Delta, Vietnam.
Authors: Nguyen Thanh Phuong 
Published: April 2021

Abstract

The two pangasiid catfish, Pangasius bocourti and P. hypophthalmus, are widely cultured in the Mekong Delta, Vietnam. However, seed supply until recently was dependent on fry and fingerlings caught from the Mekong River. In 1994, a research programme was carried out on artificial seed production of these two species in captive conditions. In 1995, about 30,000 fingerlings were first produced in An Giang and Can Tho provinces and a proper technique of induced breeding, progressive human chorionic gonadotropin (hCG) treatment, was determined. This technique, involving two steps of hCG injections, successfully induced ovulation in 66% of 67 treated females of P. bocourti. Application of this technique to other pangasiid catfish species such as P. conchophilus, P. hypophthalmus, P. mekongensis, and P. larnaudii also resulted in breeding success. Research on larval rearing has also been conducted to improve the growth and survival of pangasiid larvae. Extension of research findings of induced breeding and larval rearing has allowed mass seed production of pangasiid catfish in the Mekong Delta.
Aquaculture systems in Hanoi, Vietnam.
Authors: Nguyen Thi Dieu Phuong 
Published: April 2021

Abstract

Hanoi, the capital of Vietnam, is one of the most densely populated areas in the world, with about 3,000 people km-2. Traditionally, aquaculture is practiced in ponds, reservoirs and urban lakes, rice fields, wastewater and VAC [an acronym from the Vietnamese words for garden (vuon), pond (ao) and livestock quarters (chuong)] systems. With over 5,000 ha of surface area and 3,000 ha of lowland rice fields, Hanoi has potential for further aquaculture development and tourism-entertainment services. The importance of aquaculture has long been recognized as a source of income and employment. Nowadays, pond aquaculture in peri-urban areas is decreasing due to urbanization, while in areas far from the city it is increasing through the conversion of lowland rice fields to fish ponds.
Ganoderma philippii (red root rot).
Authors: Paterson R. R. M. 
Published: April 2021

Abstract

G. philippii was described as a root pathogen that is particularly destructive to tropical plantation crops, especially rubber (Steyaert, 1975a). It occurs on many woody and non-woody plant hosts in South-East Asia through Indonesia to Papua New Guinea and New Caledonia (UK CAB International, 1993). Acacia trees are considered as invasive species and as an economic crop (Koutika and Richardson, 2019) and the significance of the disease is from both aspects. A similar situation exists for other trees such as Eucalyptus (Deus et al., 2019). These trees are being considered to combat climate change by absorbing carbon dioxide and consequently disease is extremely important. Red root rot is a significant disease of tropical plantations in South-East Asia. In severely infected areas in Malaysia, root rot caused more than 40% mortality of Acacia trees aged between 9 and 14 years. In Indonesia, the disease can kill up to 28% of trees in second-rotation A. mangium plantations in Sumatra and Kalimantan. Second rotation A. mangium and A. crassicarpa plantations trees as young as 6 months old may be killed by red root disease (Gafur et al., 2015).
Spodoptera frugiperda (fall armyworm).
Authors: Rwomushana Ivan 
Published: April 2021

Abstract

The fall armyworm, Spodoptera frugiperda, is a lepidopteran pest that feeds in large numbers on the leaves, stems and reproductive parts of more than 350 plant species, causing major damage to economically important cultivated grasses such as maize, rice, sorghum, sugarcane and wheat but also other vegetable crops and cotton. Native to the Americas, it has been repeatedly intercepted at quarantine in Europe and was first reported from Africa in 2016 where it caused significant damage to maize crops. In 2018, S. frugiperda was first reported from the Indian subcontinent (Ganiger et al., 2018; Sharanabasappa Kalleshwaraswamy et al., 2018). It has since invaded Bangladesh, Thailand, Myanmar, China and Sri Lanka (IPPC, 2018b, 2019; FAO, 2019c). The ideal climatic conditions for fall armyworm present in many parts of Africa and Asia, and the abundance of suitable host plants suggests the pest can produce several generations in a single season, and is likely to lead to the pest becoming endemic.
Bromelia pinguin (wild pineapple).
Authors: Dube Shruti 
Published: April 2021

Abstract

Bromelia pinguin is a large, perennial bromeliad with spikey fronds that grow up to two metres long. It often grows in dense colonies. It is native to the Neotropical Region but has been introduced as an ornamental to Florida, Hawaii and other Caribbean islands as well as India and Sri Lanka. Though some sources consider it native to Cuba, it is also recorded as invasive, where it is invading forests and savannahs, displacing native vegetation and providing a niche for small invasive mammals. It is also an alternative host to Pineapple mealybug wilt-associated virus 2 (PMWaV-2), which threatens commercial pineapple farming in Cuba.
Fallopia sachalinensis (giant knotweed).
Authors: Shaw Dick 
Published: April 2021

Abstract

F. sachalinensis is a highly invasive rhizomatous perennial plant capable of reaching 4 m in height, outcompeting and displacing native species in particular in riparian zones which it prefers. It has spread to most areas in its exotic range without the aid of seed dispersal though it does provide pollen for the fertilization of F. japonica plants to produce the highly invasive Fallopia x bohemica. Though not considered as problematic as Japanese knotweed (F. japonica), eradication is a real challenge and often unachievable, especially with restrictions applied to chemical use on or near water thus methods of control are limited.
Ipomoea indica (ocean blue morning-glory).
Authors: Rojas-Sandoval Julissa 
Published: April 2021

Abstract

Ipomoea indica is a vine that has been widely cultivated as a garden ornamental across tropical, subtropical and warm temperate regions of the world (Randall, 2017; USDA-ARS, 2017). It is an aggressive and opportunistic colonizer of open and disturbed habitats that has escaped from cultivation to become widely naturalized in disturbed areas near gardens, coastal areas, forest edges, and along roadsides and waterways. This species spreads by seeds, stolons, and stem fragments and when growing under favourable environmental conditions (e.g., full sun, ample moisture and fertile soil) it can spread very rapidly, smothering all other vegetation growing nearby. Its rapidly growing stolons can form dense mats over the ground, while its climbing habit enables it to compete successfully with trees and shrubs on the edges of forests and along riparian zones. Its twining stems also choke adjacent seedlings and smother young trees and shrubs in the understory (Wagner et al., 1999; Csurches, 2016). Currently, I. indica is listed as invasive in Australia, New Zealand, China, southern Africa, Europe, the West Indies, and on many islands in the Pacific Region (Smith, 2010 BioNET-EAFRINET, 2017; DAISIE, 2017; Flora of China Editorial Committee, 2017; GRIIS, 2017; PIER, 2017; Queensland Government, 2017).

Authors: Rojas-Sandoval Julissa 
Published: April 2021

Abstract

Macroptilium atropurpureum is a perennial herb widely cultivated across tropical and subtropical regions of the world as a forage crop, a soil and pasture improver and for ground cover. It is native to tropical America and has been introduced across Africa, Asia, the Caribbean, Australia and many islands in Oceania. Outside its native distribution range, and in some areas inside its native range, this species is a weed of disturbed sites, roadsides, secondary forests and ungrazed areas. It can form dense stands along forest margins and can also smother native shrubs, grasses and young trees. It has a deep-rooting system and can tolerate extreme drought conditions. Currently, M. atropurpureum is listed as invasive in Hawaii, the Dominican Republic, India, Australia and many islands in Oceania including, Fiji, Palau and Tonga.

Abstract

Cosmos sulphureus is a prolific seed-producing annual herb considered native to Mexico and northern South America. It grows to two metres tall, and sports very attractive heads of yellow flowers. There are numerous popular cultivars of C. sulphureus in the international horticultural trade, resulting in its wide and intentional spread by humans. The species has been known to escape cultivation and to naturalize. It is recorded as an environmental weed and occasionally as an invasive plant in parts of Africa, Asia, North and Central America and Pacific Islands though details of impact are lacking.
Cananga odorata (ylang-ylang).
Authors: Datiles Marianne Jennifer 
Published: April 2021

Abstract

Cananga odorata is a fast growing tree, native to Southeast Asia. It was introduced by humans to the Americas, China, India and Africa for a variety of commercial purposes, including as an ornamental, a source of timber and for its fragrant perfume oils. Its use as a perfume oil have deemed it an important agroforestry species. Although not currently considered to be a high-risk invasive species, it is listed as invasive to many parts of the Pacific and is considered weedy in Central Africa and Pohnpei, and 'persistent' in Puerto Rico. It is also listed as a cultivation escape in Saint Lucia and Costa Rica. As it is pioneering in disturbed areas, a fast grower and can reach heights of up to 30 m tall, the species does possess invasive characteristics that could pose a negative environmental impact.

Breynia disticha (snowbush).
Authors: Vélez-Gavilán Jeanine 
Published: April 2021

Abstract

B. disticha is considered as an invasive shrub to small tree in USA (Florida and Hawaii), Guinea, The British Indian Ocean Territory, Niue and Cuba (Oviedo Prieto et al., 2012; Swearingen and Bargeron, 2016; PIER, 2017). The species invades areas close to where cultivated by root suckers (PIER, 2017). In Cuba it is considered as a transformer species, without further details (Oviedo Prieto et al., 2012). It is regarded as an invasive species in Florida-USA by Swearingen and Bargeron (2016), although it is not in the Florida Exotic Pest Plant Council's list of invasive plant species (Florida Exotic Pest Plant Council, 2017). At Dave's Garden (2017) it is considered by the community as an invasive species in southern Florida, having the ability to spread quickly from roots in damp soils. It is not considered as an invasive species for Florida by Gilman (2014). In Hawaii-USA it has escaped from cultivation and is spreading vegetatively around abandoned homesites in Hawaii (PIER, 2017). In Guinea, the green-form of B. disticha is considered as an invasive species along the roadsides, in secondary thickets over many hectares, at the edge of a mangrove and in woodlands (Cheek et al., 2013). As its been found in areas with no evidence of former cultivation, apparently spreading through seeds. It has been collected in fruit at one of the sites. No details about its invasiveness are given for the British Ocean Territory and Niue.
Launaea intybacea (bitter lettuce).
Authors: Rojas-Sandoval Julissa 
Published: April 2021

Abstract

Launaea intybacea is a fast-growing herb that grows as a weed in disturbed sites, and waste and cultivated land. Its ability to succeed on ruderal and disturbed sites has made L. intybaceae the most widespread species of the genus. This species is also adapted to dry conditions and thus can be found growing in dry and semi-arid habitats. L. intybacea spreads by seeds which can be easily dispersed by wind and water and as a contaminant in soil, on agricultural machinery or stuck to vehicles and clothing. Currently it is listed as invasive in the Bahamas, Cuba and the Dominican Republic and as "potentially invasive" in Jamaica, Aruba, Curacao, Bonaire, St Eustatius and Grand Cayman.
Macrothelypteris torresiana (swordfern).
Authors: Rojas-Sandoval Julissa 
Published: April 2021

Abstract

Macrothelypteris torresiana is a perennial fern native to Asia, Madagascar, the Mascarene Islands and Oceania. It has been widely introduced across the Americas as an ornamental plant. It grows in disturbed areas including roadsides and forest edges and behaves as a weed. It spreads via spores in wind and water but can also spread via stolons and rhizomes in garden waste. Currently, M. torresiana is listed as invasive in Cuba and Brazil and may also be invasive in Hawaii where it is spreading. The impact of this species where it is invasive is largely unknown, but it is possible that its weedy and opportunistic nature results in competition with native species and alteration of successional patterns.

Authors: Rojas-Sandoval Julissa 
Published: April 2021

Abstract

P. paniculatum is a fast-growing grass sometimes used as an "auxiliary forage" crop (PROTA, 2016). Within and outside its native distribution, P. paniculatum behaves as an environmental and agricultural weed and can be found growing along roadsides, in disturbed places, moist shrublands, low open grounds, brushy slopes, forests, open ground, croplands and pastures (Zuloaga et al., 2003; Más and Garcia-Molinari, 2006; Más and Lugo, 2013; AusGrass2, 2016). Plants produce numerous seeds with germination rates higher than 85% (range: 86.5 to 99%, PROTA, 2016). Currently, this species is listed as invasive on Hawaii, Cuba, Trinidad and Tobago, Samoa, Northern Marianas Islands, Micronesia, Fiji, French Polynesia, New Caledonia, Niue, Palau and the Solomon Islands (Wagner et al., 1999; Oviedo Prieto et al., 2012; PIER, 2016; Trinidad and Tobago Biodiversity, 2016).
