Abstract

Mudcrab (Scylla serrata Forskal) is one of several dominant species in the fish production from Karangsong coastal waters, Indramayu Regency. However, effort to manage the mudcrab in the waters is still limited. This study aimed to estimate a growth of the mudcrab as a base for crab management at the waters. Monthly sampling of the crab in the study area was conducted according to fisherman catch using bamboo trap for 4 months (Juni-September 2013). Carapace width and weight were employed for calculating frequency distribution, growth pattern, and growth. Growth estimation of the crab was calculated using Von Bertalanffy equation. This study revealed that the carapace width of the mudcrab ranged of 60-138 mm (male), and 74-139 mm (females). Crab’s growth patterns of the mud crab was negative allometric, W = 0.0003L2.8793 (male) dan W = 0.003L2.3210 (female). Through analysis of growth parameter estimation, it was obtained the following equatiosn: Lt = 157.35 [1-e(-0.39(t+0.26)] (male), and Lt = 147.99 [1-e(-0.42(t+0.24)] (female).

Abstract

The release of organic waste into the waters due to the Eel (Anguilla sp.) rearing activity will cause eutrophication. Efforts to reduce organic waste can be done by using local mussel (Pilsbryoconcha exilis) because it has biofiltration capabilities. The purpose of this study was to determine the ability of local mussels in reducing organic waste. The research design used in this study was a randomized block design (RBD), with treatment in the form of differences in waste concentration (50% and 100%), while the group was in the form of differences in the size of the gravestone (small, medium, and large). The results showed that mussel was able to reduce organic matter, the effective time of local mussel (P. exilis) to reduce organic waste from the cultivation of eel (Anguilla sp.) Was in the first 6 days. The most effective treatment is the use of 100% waste concentration and small mussel. This treatment was able to reduce COD values ​​by 66.1 mg/L (28%), turbidity by 187.2 NTU (16%), TSS by 134 mg/L (36%), and ammonia by 0.004 mg/L (24%), and increased biomass by 7.21 grams (3%).

Abstract

Microplastics that pollute waters can accumulate and clog in the digestive tract of fish. It is still not well known whether microplastics can be digested by fish or not. Therefore, this research is important. The purpose of this study was to analyze the ability of digestive fluids in fish to digest microplastics in vitro. This research was conducted from January to April 2021 at the Laboratory of Aquatic Animal Physiology and Environmental Productivity (ProLing), Faculty of Fisheries and Marine Science, IPB University, Bogor. This research consisted of two stages, namely preliminary research (prelim test) and core research (core test). The parameters observed consisted of the digestive fluid performance (temperature, pH, turbidity) and microplastic conditions (size, color, and shape). The measurement results for each parameter of the digestive fluid performance of catfish (carnivore) and tilapia (omnivore) showed that there was no significant change in value for each treatment. Observation of the condition of microplastics after testing also showed no change in microplastics. This proved that in vitro fish digestive fluids were unable to digest microplastics.
