Abstract Eel has a savory meaty taste and contains high levels of Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA). The purpose of this observation was to determine intensive rearing techniques for eel (Anguilla bicolor bicolor) at the UPTD KPSDKP for Conservation and Supervision of Marine Fishery Resources of Sicincin, West Sumatra. The preparations conducted for rearing the eel consist of providing seeds, pond preparation, water supply, feed management, water quality control, disease control, growth sampling, and harvesting eel for consumption size. The eel seeds were obtained from natural catches of glass eel in the Cimandiri river, Pelabuan Ratu, West Java. Preparation of the eel pond included cleaning the concrete pond, filling the water by observing the water input into the eel pond. The provision of water for eel rearing was obtained directly from the Kapalo Ilalang Sicincin irrigation channel to the holding tanks before flowing to the eel rearing pond. Feeding management was carried out 2 times a day, namely the percentages of feeding in the morning (35 %) and at night (55%) with a feeding rate of 3%-5%. The feed provided to these eels was in the form of a paste made of powdery pellets. Measurements of water quality for eel rearing during observations were temperature (27-29°C), pH (6-7), DO (5.9-7.8 ppm), salinity (3-4 ppt) and NH3 (0.02-0.07 mg/l). In our observations, parasites shaped like cotton were discovered, which attacked the eel body, causing death. In growth sampling, the measurement of the length and body weight of the eel once a month is necessary to be done.

The cassava residue was selected as carbon source to study the effect of biofloc technique (BFT) on water quality control, growth performance and seedling emergence in a 40 L culture water of litopenaeus vannamei nursery culture system. The BFA groups included Graded level of C/N (15/1, 20/1 and 25/1) with three parallel samples, compared to the control groups. At the end of the feeding trial 15 days, 10.7%, 14.4% and 46.8% significantly decreased in NH4+-N concentration of the graded level of C/N (p<0.05); 80.2%, 96.0% and 96.2% distinctly decreased in NO2--N concentration (p<0.05); 81.4%, 57.8%, 151% obviously increased on seedling emergence (p<0.05) and 52.2%, 80.8%, 18.2% obviously increased on body weight (p<0.05). The present study elucidates that in the nursery system adding cassava residue as carbon source the culture water quality was evidently improved and heterotrophic bacterium, phytoplankton and zooplankton was also effectively obviously promoted.

This article mainly starts with the concept and basic characteristics of China’s marine fishery resources. On this basis, it analyzes the utilization status of China’s marine fishery resources and the problems existing in the management of marine fishery resources for discussion, and finally proposes effective ways to strengthen the management of marine fishery resources, aiming at providing help for the sustainable development of China’s marine fishery resources.
