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

Vaname is one type of shrimp that is often cultivated in Indonesia. The shrimp farming system model consists of an extensive system (traditional) and an intensive system. This study aims to compare the abundance of plankton, water conditions, growth performance of vannamei shrimp (Litopenaeus vannamei) in intensive and extensive aquaculture systems in the waters of Banyuwangi Regency. Parameters measured include physical and chemical parameters, namely temperature, brightness, pH, dissolved oxygen, salinity, ammonia, and alkalinity, type and abundance of plankton. The research method used is descriptive method. The method of analysis is the abundance of plankton, and analysis of productivity, SR, FCR and growth of vannamei shrimp. The results showed that plankton in intensive pond waters were identified as many as 4 classes, namely phytoplankton class Chlorophyta, Cyanophyta and Chrysophyta, while zooplankton class Protozoa. In traditional ponds, it is not much different, only the Crpytophyta class as an additional identification result. The abundance of plankton in intensive ponds reaches 27,595 individuals per liter, while for extensive ponds the abundance of plankton reaches 37,641 individuals per liter. While the survival rate of shrimp in intensive ponds is around 86%, while in extensive ponds is 67%. The FCR value for extensive ponds is 1.02, while the FCR value for intensive ponds is 1.17. The final average weight of shrimp in intensive ponds was 11.76 g/head and 8.33 g/head in extensive ponds.Keyword : Vaname Shrimp, Intensive Cultivation, Extensive

Abstract

The most important coastal socio-cultural management is the economic management of fishermen. As an archipelagic country, most of its territory consists of oceans, Indonesian fishermen should have a prosperous level of economic life. However, there are still many fishermen who are classified as poor. To improve the socio-cultural elements of the fishing community in Indonesia, a high entrepreneurial ethos is needed. This relates to the management of marine fisheries business. Aspects of short and long term planning must be prepared in detail. Sustainable development is needed to foster better utilization of marine resources. Social conditions are also related to the activities of fishermen in a social organization. Cultural conditions are the use of methods and technologies that have been used for generations to catch fish. Marine aquaculture innovation, providing freedom in a responsible manner, and respecting the rights of everyone can be done to improve the welfare and socio-cultural management of the coast. Socio-cultural transformation will give direction to economic transformation. The effort needed is to increase the knowledge of fishermen. The surrounding companies should provide business opportunities for local communities. Government policies will determine the success of coastal socio-cultural management.Keywords: management, coastal, socio-cultural

Abstract

Indonesia has enormous potential in the field of fisheries, this is because about 70% of its territory is oceans and archipelagic countries. Shrimp farming in Indonesia is a practice that is widely practiced by Indonesians. This is because shrimp is a fishery commodity that has the highest demand. Aquaculture Base Group (ABG) aims to manage communities, who were originally individuals in managing ponds to become groups, because it will make it easier to get support from the government and get more benefits than only individuals. The program is implemented using several methods, namely socializing the importance of cultivation using the ABG method, explaining the advantages of using the ABG method, forming cadres for coordination between extension agents and the community so that communication can be evenly distributed, and distribution for each pond and job desk. As well as the holding of monitoring and evaluation, whether to get more efficient results when using ABG or individual methods. The ABG method is more efficient than using the individual method, including fry and feed can be purchased at a lower price, fry can be done together so that supervision will be easier, management of water sources is more maintained, and biosecurity is easier, and the impact of management be the responsibility of groups not individuals. Conclusion: the use of ABG cultivation method is more efficient, get affordable prices when buying fry and feed, disease management that can be managed together, cheaper electricity, easier biosecurity and more maintained water management (Tandon and Waste Water Treatment Plant) .Keyword : Fishery, shrimp farming, group, sustainable

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

Shrimp aquaculture wastewater after the end of the rearing period has a high total organic matter (TOM) content of up to 87.74 mg/L. If the wastewater is disposed of directly without any efforts to reduce or treatment, it will disturb public waters ecosystem because of the high organic matter. The aim of this study was to determine the rate of reduce of organic matter in pond aquaculture waste. The study was carried out in January 2021. Pond wastewater samples were taken from the Tambak at the end of the maintenance period (120 days of maintenance). The trademarks of the bacterial consortium are EM4, Bio HS, BIO Prisma, Starbio plus, BIO2000, and Biolet. The experimental research was arranged in a completely randomized design with 6 treatments and 4 replications. Each treatment was filled with 2 liters of wastewater plus 6 ml of a liquid bacterial consortium. As for the solid bacterial consortium, 1 gram/L was added. Measurements of total organic matter, temperature, pH, dissolved oxygen, salinity and carbon dioxide were carried out every 24 hours for 72 hours of observation. The results showed that during 72 hours of immersion the highest percent reduction in organic matter was in treatment E (BIO 2000) of 95% (87.74 mg/L to 4.11 mg/L). The lowest percentage decrease was in treatment D (Starbio plus) of 83.4% (87.74 mg/L to 14.54 mg/L). However, in general 6 types of bacterial consortium trademarks can degrade organic matter. The levels of temperature, pH, dissolved oxygen and salinity are in optimum conditions, while carbon dioxide exceeds the threshold caused by the high activity of overhauling organic matter by bacteria. The conclusion was obtained that the trademark of the bacterial consortium BIO2000 was the most effective in reducing organic matter for 72 hours.Keyword : Shirmp wastewater, Tambak, Bioremediation, Organic Matter, Microorganis
