One of the issues with green mussels is the high content of the heavy metal Lead (Pb) in their flesh, which is caused by heavy metal accumulation in the waters. The goal of this study was to isolate, characterize, and test the ability of heavy metal Lead-Pb bacteria to biosorb heavy metal Pb in post-harvest green mussels from sediments and green mussels in the Banyu urip Ujung Pangkah Gresik Sea. The stages of the research included sampling, isolation, macroscopic and microscopic characterization, in vitro testing of Pb heavy metal absorbent. The results showed 6 bacterial isolates, namely two from green mussels coded K1 and K2 and 4 bacterial isolates from marine sediments coded S1, S2, S3 and S4. The six bacterial ...

A challenge in green mussel cultivation is the presence of diseases caused by parasites that attach or live on the mussels. This research aims to determine the abundance of ectoparasites and competitors on green mussels in the mentioned waters. The research methods employed both qualitative and quantitative descriptive approaches. The observed research variables included species identification, prevalence and intensity of ectoparasites, as well as diversity and abundance of competitors. The findings revealed the presence of 2 ectoparasite species and 10 competitor species. The highest prevalence of Balanus sp. was recorded in Bagan Tancap I for mussels larger than 4 cm, at 79.6%±6.16 (moderate), while the lowest prevalence was in Bagan Tancap II for mussels smaller than 4 cm, at 33.3%±1.05 (common). The highest intensity of Balanus sp. ectoparasite attacks occurred in Bagan Tancap I for mussels larger than 4 cm, at 7.18 ind/mussel (moderate), and the lowest intensity was in Bagan Tancap II for mussels smaller than 4 cm, at 1.75 ind/mussel (low). The intensity of sea snail egg infestations ranged from 1 to 2 ind/mussel, with no significant difference (P>0.05). The highest competitor abundance was found in Bagan Tancap I with the species Nereis sp., at 0.57 ind/mussel, and the highest competitor diversity was also observed in Bagan Tancap I with the species crab at 36.292 ind/mussel. Considering the prevalence and intensity values of Balanus sp. ectoparasites on green mussels in the waters of the Java Sea in Kecamatan Sidayu, it is still suitable for green mussel cultivation.

High demand of this fish has been triggering many aquaculturist to culture C. stiata. Feed was the important factor for fish growth. Silkworm has high protein content, low fat and can be used as natural feed for finfish. This study investigate the silkworm feed in C. striata. The treatment of this research were A (100 % pellet); B (100 % silkworm); C (combination of 75 % pellet and 25 % silkworm); D (combination of 50 % pellet and 50 % silkworm); and E (combination of 25 % pellet and 75 % silkworm). The variables measured in this study were relatif growth, specific growth rate, feed efficiency, feed conversion ratio, and survival rate. The result show that silkworm gave the high growth performance, feed efficiency and survival rate of the snakehead (Channa striata) compared with the control.

The livelihoods of most residents are traders, builders, factory workers, laborers, private employees and teachers. Wiyung which is part of Surabaya City, the second largest Metropolis City in Indonesia, feels the impact of the development of the city. The bad impact is the high pollution both air, soil and water. Air pollution comes from high smoke from motor vehicles and factories. This causes a lack of access to clean and healthy oxygen and a comfortable and beautiful place to stay free from pollution. For this reason, this community service program is implemented with the aim of providing education about a healthy and beautiful environment to residents, especially school age children. School-age children were chosen because they have great opportunities to develop and there are wide open opportunities to hon...

From the milkfish commodity, Gresik is the center of fishery production in East Java. Milkfish belongs to the herbivore group with the type of food from the plant group. Milkfish cultivation in traditional ponds still uses natural food as the main food for the cultivated commodities. Fish food affects the structure of the digestive tract, especially the intestines of fish. herbivorous fish have very long intestines even many times the body length, compared to omnivorous and carnivorous fish. Thus, this study aims to find out more clearly about the structure of the milkfish gut tissue. The digestive tract is related to the process of digestion, absorption and disposal of food waste, so it has an important role in the growth of fish. The research method used was descriptive experimental by making preparations of fish intestinal tissue and staining with Hematoxylin Eosin. The intestines of the fish observed were the front, middle and...

This material contains chitosan as a valuable compound characterized as a non-toxic structural component with several food processing applications or medicinal applications. In this research, mussel shells were processed using different solvents concentrations in several stages: demineralization, deproteination, decolourization, and deacetylation. Our result showed that the C2 samples gained a high degree of deacetylation (31.8±0.21%) with low moisture and ash content and medium weight of yield. Further research is recommended to purify chitosan using various instrumentation and assess its bioactivity.

Kegiatan budidaya ikan umumnya terfokus pada usaha pembesaran ikan, baik dalam areal pertambakan maupun perkolaman, baik tawar hingga bersalinitas. Salah satu komoditas perikanan dari perairan tambak Kabupaten Lamongan adalah ikan nila.
