Authors: Syahrial  , Desrita  , Ezraneti R. 
Published: April 2021

Abstract
Coastal environmental damage often occurs in various regions, especially around the mangrove forest area. Generally caused by anthropogenic which is increasingly high and causes mangrove habitat to change and gives great pressure on the biological community that inhabits it. One of the main objectives of bioindicators is to identify species or groups of species that can indicate environmental disturbances, so this study aims to determine or assess how suitable species or groups of Littoraria species as bioindicators in monitoring programs in coastal environments, especially mangrove ecosystems. The results of the study concluded that Littoraria spp. can be used as a species or group of bioindicator species. This is because they have fulfilled the requirements that must be fulfilled by an organism to be used in the biomonitoring program. However, the criteria for Littoraria’s spp. relationship with other species is still unclear, so they must be used with caution.

Abstract
Effect of Indian Ocean Dipole (IOD) was highly significant on term of environments parameter variabilities at the Indian Ocean. Variation in the abundance and distribution of yellowfin tuna have been well known associated with environment parameters that drive by large-scale climatic indices such us Indian Ocean Dipole. To better understanding on yellowfin tuna fishing activities at the Western waters of Sumatera, we investigated hand line fishing catch during 2016 and 2017 as the IOD negative and positive events representation. Our result showed significant different fishing variabilities between year with negative and positive indices. Mean annual yellowfin tuna catch significantly higher during positive IOD both of abundance and weight, following by mean annual catch per unit effort (CPUE). During positive IOD hand line fishing trips were significantly lower compare than negative IOD. We also evaluated the geographic distribution of hand line fishing activities, we found that fishing activities cover significant wider area during positive IOD. In the opposite, during negative IOD yellowfin tuna fishing activities became centralized. This study gave us new perception on large-scale climatic events effect on yellowfin tuna fishing activities at a narrow study area.

Abstract
The coastal area of East Lingga Subdistrict, Lingga Regency has been designated by the Lingga Regency government as the center for the development of shrimp pond cultivation. This study aims to determine the level of toxicity of the surfactant alkyl sulfate (AS) detergent to post larvae (PL) of Vannamei shrimp (Litopenaeus vannamei). An acute test was performed on PL10 samples exposed to AS media for 96 hours. Then the Median Lethal Concentration (LC50) value was calculated for 4 times (24 hours, 48 hours, 72 hours, and 96 hours). Furthermore, the PL-15 sample was AS in the sub chronic test, then the sample was exposed to AS media for 24 hours, then the growth rate and changes in the gill organ structure of the PL samples were observed. From the test results, it is known that the LC50 values in the AS test for the 24th, 48th, 72th, and 96th times of the shrimp larvae samples obtained LS50 values were 33.6 mg/l, 29.4 mg/l, respectively. 24.3 mg/l, and 22.8 mg/l. Subsequently, an increase in AS concentration by 17.11 mg/l in the rearing medium resulted in a decrease in the growth rate of post larvae. The acute and sub chronic testing period showed changes in the behavior of post-larvae samples. The histopathological observations found damage to the structure of the sample gill organs and hepatopancreas. Symptoms of damage to the structure of the gills began to appear at AS concentrations of 25.58 mg/l at time 96 and 72 with an LC50 value of 34.99 mg/l. Furthermore, it was also seen at an AS concentration of 9.78 mg/l at time 24. The results of this study found that AS toxicity to Vannamei larvae increased with increasing concentration and exposure time.

Abstract
Millions of people lost their jobs due to COVID-19 creating critical problems of food and nutrition insecurity. It has added 130 million in addition to 821 million hungry people [1]. Over 690 million people are malnourished. Fish is the best medicine of malnutrition and the most efficient food production system; tilapia is the most suitable one. It became the most widely farmed species due to availability of inputs, equipment, technologies and human resources. To solve the shortages of seed, AIT developed a technique capable of producing millions of mono-sex seed. It is spreading from Fiji through Asia, Africa to Brazil. Tilapia is grown in low input ponds to highly intensified cages and tank systems. China produces over 1.5 million ton annually, followed by Indonesia and Egypt. Globally about 7 million mt of Nile tilapia along with its hybrids, is produced annually which is the highest amongst the species. Tilapia is available in the street as well as supermarkets in Asia and frozen fillets are popular in USA and Europe. It has great scope to create millions of jobs and generate income in addition to ensuring food and nutrition security if it could be aggressively promoted worldwide.

Abstract
Arafura Sea is rich in its resources, e.g. shrimp, pelagic fish, demersal fish, and coral reef fish. Coral reef fish commonly found in Arafura waters are among others brown-marbled grouper, slender grouper, leopard coral grouper, humpback grouper, etc. One of the groupers that has a higher selling price than the other groupers is slender grouper (Anyperodon leucogrammicus). The high demand for the fish is in line with the increase in the catch and the exploitation status. Therefore, a study is necessary to analyze the exploitation status of the slender grouper in Arafura Sea. This study was carried out from March to November 2017 by sampling the grouper at its landing site in Dobo, Aru Islands, from the fishing grounds in Arafura Sea, Maluku. The size of the slender grouper was 15–120 cm TL, and its growth pattern was allometric negative. Its growth rate (K) was 0.34 per year and its fishing mortality (F) was higher than the natural mortality (M). The exploitation rate (E) of the fish was 0.52%, meaning the fish was already moderately exploited. Therefore, precautionary managements are necessary to maintain the sustainability of the slender grouper resources in Arafura Sea.
