Abstract

Pelagic fish resources have a very important role in regional economic development. The assumption that fish resources are common property so that everyone is free to catch (open access) is a problem with overfishing in East Java waters. The purpose of this study is to determine the superior commodity of small pelagic fish, the status of exploitation of superior  fish resources and to compile a scenario of sustainable management of superior resources. The method in this research is quantitative descriptive method with data analysis used including Location Quotient (LQ), Schaefer (1954), Fox (1970), Walter Hilborn, and programming STELLA (System Thinking, Experimental Learning Laboratory with Animation). The research result of the superior species in the province in the south of East Java) is sardin, while the superior fish in the regency is s Rainbow runner. The status of fisheries at the level of superior fisheries exploitation in South East Java, the level of exploitation of ssrdin fish is 240% with the status of Depleted. Finally, the level of exploitation for s Rainbow runner fish is 689%, which means that they are included in depleted. The scenario of sustainable management of pelagic fisheries for the next 10 years, namely 2018 - 2027 for lemuru fish, the highest biomass reserves will be obtained in 2027, using a fixed effort allocation which has biomass reserves of 179% and the potential value of sustainable reserves of 8,438.48 tonnes. The results showed that the superior commodities of small pelagic fish in North East Java were mackerel fish. The superior fish commodity in the Regency / City is obtained by Finny scad fish. The level of exploitation for mackerel is 127% with the status of Over Exploited, and the level of exploitation for Finny scad is 131% with the status of Over Exploited. The scenario for the management of the superior mackerel commodity, the highest biomass reserve in 2027 is the allowable fishing effort allocation (fJTB) of 129%.Key Words: STELLA ,Superior commodity, Fishery status, Sustainable potential

Abstract

Red tilapia is one of the commodities that can be cultivated in the running water pond. With the technology of running water ponds that depend on feeding. The cost of feed in production ranges from 60-70% of the total cost. Therefore, innovation in feed is needed to reduce production costs. Then an experiment was carried out aimed at finding out the efficiency in feeding maggot and pellet feed in red tilapia in the running water pond system. Some experiments were carried out by giving full feed pellets and substitution in maggot feed 50%. This research was conducted 75 days from March 2, 2020 to May 15, 2020. Observed parameters were production technique from stocking to harvest, frequency and dose, feed conversion ratio, daily weight gain, survival rate, and parameters water quality (pH, temperature, dissolved oxygen and water discharge). Daily average weight observations are carried out once a week. By providing different feeds, FCR is higher and pellet feed is superior to maggot and pellet combination feed. Pellet feeds produce FCR 2.8 and maggot and pellet combination feeds produce 3.79. With the loss of using maggot mixed feed IDR 15.709.111. Based on these results maggot feed experiments given did not provide a better effect than giving full pellet feed.Keywords: Experiment, red tilapia, different feeding, maggot, FCR, Financial Analysis.

Abstract

Catfish (Clarias sp.) is one of Indonesia's leading fishery commodities whose production continues to be increased. Humic acid is known to help increase growth in several types of fish and is expected to be applied to catfish. This study aims to determine the effect of humic acid in commercial feed on the growth and total number of bacteria in the digestive tract of catfish (Clarias sp.). A total of 300 catfish with an average length of 5.76 ± 0.21 cm and an average weight of 27.92 ± 0.39 g were used in 5 treatments (4 replicates/treatments) of humic acid supplementation in feed with different doses, namely P1 (without humic acid/control), P2 (0.5 %), P3 (1.0%), P4 (1.5 %), and P5 (2.0 %). Maintenance was carried out for 40 days by feeding treatment 3 times a day as much as 5% of body weight. Parameters observed were absolute length growth (cm), absolute weight growth (g), specific growth rate (%), and total bacteria in the digestive tract (colonies/g). Based on the results of the study, it was found that the treatment had a significant effect on the growth and number of bacterial colonies with the optimal dose of humic acid of 0.5.Keyword : Behavior, Doses, Control, Colony

Abstract

Eel (Anguilla sp.) is one of the important commercial fish in some countries particularly in East Asian countries such as Japan, South Korea, China, and Taiwan. The need of eel fry or frequently called as glass eel still relies on the natural capture. The issue of natural captured fish is the high level of bacterial infections and diseases. The dependence of glass eel from the nature provides an indication of infections of parasites and bacteria in glass eel. The existence of parasites and bacteria as microorganisms which are potential as pathogenic agents in the cycle of eel culture can be a serious obstacle, so that the glass eel handling needs a particular attention since the capturing proses from the nature. Therefore, identification of parasites and bacteria in the capture location of glass eel was necessarily conducted in Pelabuhan Ratu Bay, Sukabumi, West Java. The glass eel sampling was conducted in May-June 2019, in 3 locations of estuary with the highest capture yield namely Cimandiri River, Cikaso River and Cibuni River. The number of samples taken were 30 eels at each river location with 2 replicates, so that the total eel samples which were taken were 180 eels. Identification of parasites was conducted by examination of ectoparasite and endoparasite and dentification of bacteria was conducted by conventional method (biochemical method). Based on the result of identification, there was no parasite found in the glass eel samples, while bacteria found as many as 12 species and 3 dominant species namely Listeria sp. found in 40 eel samples with prevalence of 22.2%, Aeromonas hydrophila found in 28 eel samples with prevalence of 15.6%, and Staphylococcus spp. found in 22 eel samples with prevalence of 12.2%.

Abstract

Baung fish is one of the local fish in West Kalimantan which has high economic value. One of the problems that arise in the maintenance of baung fish larvae is the low survival and growth rate, the most strategic solution is to determine the right type of feed according to the feeding habits of the baung fish larvae. The purpose of this study was to obtain the type of natural food that was most effective in rearing the larvae of fish. The research design used a completely randomized design (CRD) with 4 treatments and 3 repetitions. Treatment types of natural feed used in this study were Artemia (A), Water Fleas (B), Silkworms (C) and Pellet Flour (D), and arranged randomly. The results of the research through analysis of variance (Anova) show that all treatments can have a significant effect on the absolute length growth rate variable and the survival rate variable. Based on Tukey's further test, the treatment that had the best effect on the growth rate of absolute length was treatment C, namely 9.20 ± cm, while the treatment with the highest effect on survival rate was treatment A which was 98.8Keywords: Natural Feed, Baung Fish, Growth, Survival
