Abstract
Common carp (Cyprinus carpio) is known as introduced fish on some lakes in Indonesia and included in herbivore fish. The common carp population in Lake is the dominant number, so that it’s become at of fishing target. Estimation of some parameters of common carp population in Lake Paniai was aimed to evaluate the growth parameters, mortality, the fishing rate and recruitment pattern. Collecting and measuring the fish sample was done in the period from February to October 2016 by using the fishing gear of gill nets with mesh sizes of 1.00 - 4.50 inches. The results showed that common carp population in Lake Paniai was dominated by individual lengths between 15-25 cm with a frequency of 55.78%, the growth pattern of male fish was allometric (-) and females were isometric. Asymptotic length (L∞) = 61.43 cm and the growth coefficient (K) = 0.32 per year. The rate of natural mortality (M) = 0.65 per year, the fishing mortality rate (F) = 0.52 per year, the total mortality rate (Z) = 1.17 per year and the exploitation rate (E) = 0.44. The exploitation rate of common carp fish was still below the optimum value, thus an attempt to catch this fish, could be still improved. Common carp populations caught by mostly fishermen have had a chance to spawning thus common carp fish population in the lake was estimated to still be preserved and could be utilized in a sustainably. Peak recruitment occurred only once in a year, namely in June.

Abstract
Water temperature and oxygen consumption are important indicators of physiological work for Penaeus vannamei. The preferred P. vannamei shrimp farming is indicated by low water temperature and oxygen consumption and this can be achieved by using nanobubble aeration. This study aims to assess the water temperature and oxygen consumption of P. vannamei postlarvae (PL) 8. In this experimental study, PL 8 at a density of 200 inds./L were treated with nanobubble aeration (16 mg/L) and compared with control (without nanobubble). The experiments were conducted with five replications. ANOVA was applied to calculate the significance level of treatments. The result showed the nanobubble influences (p<0.05) on temperature in which treatment (23.070C; 95%CI: 22.9 to 23.3) was lower than control (27.170C; 95%CI: 27.1 to 27.2). The apparent influences were also observed in oxygen consumption (p<0.05) in which the nanobubble can reduce the oxygen consumption up to 66%. To conclude, the nanobubble has shown a positive influence on P. vannamei shrimp farming as nanobubble is able to allow oxygen to last longer in water and reduce oxygen consumption as well.

Published: May 2021

Abstract
Red claw crayfish (Cherax quadricarinatus) is nationally and globally classified as an invasive species. One of the main distribution areas of this species is Lake Lido, Bogor regency resulting from private fish cage development. This invasive species is highly possible as either competitor, predator, pathogen, or parasite carrier to the native species that are harmful to the lake water ecosystem equilibrium. Unfortunately, there is still a lack of policy management to limit the potential of its wider distribution. The research aims to analyze policy priorities in managing invasive species of C. quadricarinatus in Lido lake Bogor. The Analytical Network Process (ANP) was then utilized as the method for this research. Based on ANP analysis, the top-three-priority policy criteria for managing C. quadricarinatus are the presence of competitor inferior species, the economic value of resources and community involvement. Overall, the most priority alternative policy for managing the red claw crayfish in Lido lake is allowing the community to utilize it with tied monitoring and suppressing of population growth. The rater agreement among the stakeholder of this alternative policy is high (0.61) that expresses the stakeholders’ similar expectations.

Abstract
Study on freshwater ecology have been long focused on subtropical habitats with few references to tropical regions including Indonesia. Zooplankton, in particular, is an important component of aquatic ecosystem as they are key player of aquatic food webs, thus a solid understanding of their community structure can be of direct benefit to freshwater ecosystem management. The spatial patterns of zooplankton diversity in Lake Tondano, Celebes Island – Indonesia were studies in 2013, with the main aim was to understand how local environmental and habitat heterogeneity driving the zooplankton community structure. We performed field samplings to collect zooplankton using a vertical tow with a 156 μm mesh plankton net from 1 meter above sediment to the surface and to measure environmental parameters using portable multi probes water quality checker from three different water columns. The sampling sites were selected to include different habitats within the lake to look at diversity of the entire zooplankton communities including Rotifers, Cladocerans, and Copepods in Lake Tondano, Indonesia. A total of 21 species of cladocerans, 31 copepods, and 60 rotifers were identified from Lake Tondano. Our result indicates a relatively low number of cladocerans which is may be associated with high predatory pressure from planktivorous fish, especially within the open pelagic zone.

Published: May 2021

AbstractThe LB SPR approach is needed to predict the ability of stock reproduction as a function of recruitment and stock sustainability. Therefore, we try to apply this technique for demersal exploited stock (Priachanthus tayenus) in Sunda Strait. The length data were collected in 2013, 2015, 2016, and 2019 by a research team from Labuan landing port. Data analysis consists of length frequency, size at maturity, selectivity, and SPR by using software from http://barefootecologist.com.au/lbspr. Results have shown asymptotic Length 320,25 mm, length at maturity (Lm50) 201,4 mm, von Bertalanffy growth rate 0,136, and ratio M/k 1.56. The SPR ofP. tayenusrange from 6-36% (average 16%), and it’s relatively under 40% and potentially unsustainable. The length at selectivity 50 percent (SL50) ranges from 154-261.36 mm and length selectivity at 95% (SL95) from 179-348.48 mm. In the 2013-2019 period, SPR was relatively fluctuating and tended to decrease, as indicated by a decrease in the length of the gonad maturity (50% and 95%) of the population. The spawning potential ratio between 6%-36% (average 16%) from 2013-2019 shown an over-exploited stock and potentially high risk to sustainability stock.
