Abstract

Vaname shrimp is one of the potential cultivation commodities to be developed, because it has quite high economic value and has become an export commodity. In shrimp farming activities, feed is inseparable, where feed is the main factor in aquaculture production. The feed used has a high protein content, but only 75% can be used as feed and the rest will settle on the aquaculture pond substrate. The remaining feed that settles will be toxic and even cause death to cultivated biota because it contains ammonia. The nitrification process is a process that can convert ammonia compounds into nitrites to overcome cultivation problems. Some microorganisms that can be utilized in the nitrification process are:Nitrosomonas, Nitrosococcus, Nitrospira, Nitrosolobus, andNitrosovibrio. One of the commercial probiotics uses a dose of 0.1 - 0.2 ppm 1-2 times in a span of one week, sprinkled evenly on the pond by aeration first because the product is in powder form. Dosage can be increased or decreased according to shrimp and environmental conditions.

Abstract

Mangrove crab is one of the fishery commodities that has high economic value and gets a lot of demand from local, regional and foreign markets. This study aims to determine the frequency of appropriate feeding on the survival and growth of mangrove crabs (Scylla serrata) reared by the silvofishery system. This research was conducted from April to May 2021 in the mangrove area of Randusanga District, Brebes Regency, Central Java. The research container used was cages made of bamboo measuring 50 cm x 50 cm x 70 cm in length, width and height, which were placed in the mangove area. The feed used was trash fish in the form of chopped trash fish with a dose of 5% of the crab biomass. This study used a completely randomized design (CRD) with 4 treatments and each treatment had 3 replications. The treatments tested were 2 times a day, 1 time a day, 1 time 2 days and 1 time 3 days. The data obtained were analyzed using analysis of variance (ANOVA) and further W-Tuckey test. The results showed that the frequency of feeding was not significantly different (p > 0.05) in the survival and growth of mud crabs reared by the silvofishery system. The water quality in the study supports the growth and survival of mangrove crabs during the study is still suitable for cultivation of mud crabs (Scylla serrata).
