Minapaddy is not something new again among farmers and fish farmers. Minapaddy cultivation taking into consideration the local wisdom in a region. Fish species cultivated in rice mina system, especially in the area of West Java, namely Cyprinus carpio, Oreochromis mossambicus, Oreochromis niloticus, Osteochilus vittatus. This research was to analyzing added value of derivative fish seed from system minapadi viewed from the socio-economic aspects. The method used feasibility analysis and described quantitatively. Based on research results of derivative value-added fish seed from the seed to the system minapadi namely freshwater aquaculture for fish seed consumption. other derivative products of salvage seeds processed into “baby fish” and the ornamental fish feeds. Minapadi can minimize the risk of losing a source of income for farmers and fish farmers.

Gill net is one of the fishing gear used by Jatigede Reservoir fisherman. The purpose of this research is to analyzed the feasibility of fish catching business with gill net in Jatigede Reservoir. This research was conducted by used data collection method (observation, questioner, literature study) and method of data analysis (feasibility business analysis). The benefits of this research is expected to be informations and references for the research who will expand a fishing business with gill net at Jatigede Reservoir. The result of feasibility of fish catching business with gill net at Jatigede Reservoir is profit value Rp. 70.890.000, Break Event Point price and production (all species of fish) Rp. 4.154/kg and 2.136kg in a year, Benefit Cost Ratio 3,37, Payback Period 2 months and Net Present Value >1 Rp. 52.820.243, the fish catching business using gill net at Jatigede Reservoir is feasible to be developed.

Research on domestication of Marble Goby [Oxyeleotris marmorata (Bleeker, 1852)] has been conducted from September 2014 until March 2015 at Research Station, Faculty of Fisheries and Marine Science, Padjadjaran University. The aim of the research is to find out optimum feed rate that produce highest growth. This research used experimental method, there are three treatments feeding living tilapia rates of 2%, 3% and 4%, respectively. Observed parameters are growth rate and water quality. The results showed that the growth rate with feeding rate of 2% to 4% of Marble Goby increase 0.52 g · d^–1 to 0.82 g · d^–1 at the second month. However, at the third month, its growth rate tends to decrease to be 0.32 g · d^–1 to 0.44 g · d^–1. Feeding up to 4% is not yet generating the optimum amount of feed to get fish growth maximum. The quality of water i.e temperature, pH and dissolve oxygen are still in optimum range. But the light penetration is below its optimum range.
