Mangrove crab (Scylla serrata) is one of the fishery commodities that have higheconomic value. In addition, mangrove crab is one of export commodities to several countries such as United States, Europe, Australia, Japan, Hongkong,Taiwan, Singapore and South Korea. In general, the fishing activities of mangrove crabs in the general waters of many fishermen use different baits,it's just not known which bait is best for catching mangrove crabs. The purpose ofthis study is to determine the effect of using different types of bait to the mangrove crab catch by using bubu and know the type of bait that is most effective against the catching of mangrove crab. This research method used Completely Randomized Design (RAL) with three treatments and three replications: P1 = shredded fish, P2 = Shark skin bark, and P3 = Chicken head bait. The parameters in this study are the number of catches, the feed response and the water quality parameters, the results of this study indicate the number of catches P1 = 55.55%, P2 = 22.22% and P3 = 33.33%. While feed response time in this research P1 = 1.61, P2 = 12.03, and P3 = 11.74. From the results of this study showed the use of different baits have a very significant effect on the number of mangrove crabs (scilla serata). While the feedback response also shows the results are very real (Fcal> Ftab).

Mangrove forest is tropical coastal vegetation that grow on muddy and sandy soils which affected by sea tides. One of important commercial species that live in mangrove ecosystem is the mud crab (Scylla serrata). Feed and water quality have been considered as critical components for supporting the growth both of weight and carapace length of this species. This study was conducted from January to February 2017 in the area of ??Ecotourism Kampung Kepiting, Bali. The influence of different natural feed such as Jerbung shrimp (Penaeus merguiensis), Mollusca, lemuru fish (Sardinella lemuru) and sea worms (Nereis sp.) on the growth performance of the mud crab were investigated. Water quality parameter data such as pH, DO, temperature, salinity and ammonium were also collected. The obtained data were analyzed by using variance analysis of Statistical Product and Service Solutions (SPSS) version 21. The result showed that the use of different types of feed have no effect on  the length of carapace, but it has significantly influence on  the specific growth rate of mud crab. Finally, different types of the given feeding were still resulted in the save range of water quality parameters for mud crab culture.

The mortality of tinfoil barb during transportation is relatively high due to the oxygen consumption rate and excretion of these fishes. Therefore, the use of an appropriate anesthetic drug becomes one of the solutions for solving this transportation problem of tinfoil barb. One of the natural anesthetic drugs with potential to be studied is Chromolaena odorata leaves. The purpose of this study is to evaluate the effectiveness of anesthetic compounds from Chromolaena odorata leaves in the closed transportation of tinfoil barb. The experimental design used was a non-factorial completely randomized design that consisted of four treatments and three replications,then followed by a Tukey test to see if there was a significant difference. The experimental treatments were A (0 ml/L of leaves filtrate), B (80 ml/L of leaves filtrate), C (90 ml/L of leaves filtrate), and D (100 ml/L of leaves filtrate). The observed parameters were fish behavior towards unconscious condition, onset time, immotilization time, survival rate, and water quality. The results showed that the shortest onset time was obtained from treatment D (100 ml/L leaves filtrate), namely 58 minutes towards unconscious condition, then the longest immotilization time was also shown by treatment D, which was 371 minutes. The highest survival rates were also shown by treatment D which were 94,33% during transportation and 76,33% during culture. The water quality parameters during the experiment were in an optimum condition of tinfoil barb. Keywords:AnestheticChromolaenaodorataTransportationTinfoil barb
