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.

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.

Abstract

The value of conversion rate and feed efficiency is a parameter for determining the quality, treatment, or feed given to the growth of Silver Pompano (Trachinotus blochii). The purpose of this study was to determine the effect of feeding frequency on feed conversion and efficiency and survival of Silver Pompano. The research method used was a Completely Randomized Design (RAL) with 3 treatments (Control namely feeding once a day, A was feeding 2 days, and B was feeding once every 3 days) with 3 replications. The best results were K treatment at 2.11 g (feed conversion ratio), 47.32% (feed efficiency), and 100% (survival). The conclusion of this study is that the treatment given during the study by ANOVA analysis did not give a significant effect on the conversion value and feed efficiency. Feeding with a frequency of 1 time a day (control) shows the best weight growth and can be applied to cultivation.   Keywords: conversion rate, feed efficiency, Silver Pompano

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) .

Abstract

Pomfret (Tracinotus blochii) is a new commodity currently the mainstay of Indonesian marine aquaculture. Pomfret's exports totaled 2,150 thousand tons in 2018. From 2017 to 2018, this number increased by 100 percent from the export volume produced in Indonesia, which was 1,075 thousand tons. Of course, there are problems that are frequently encountered in the development of cultivation, such as the attack of ectoparasite worms. In this study, the silver pompano was found to be infested with the Pyragraphorus hollisae worm. The purpose of this study is to determine the prevalence and intensity of the ectoparasite worm Pyragraphorus hollisae in silver pompano (Trachinotus blochii) in Lampung waters, Sumatra, Indonesia. This is an experimental laboratory study, and the study design is a cross-sectional study. The purposive sampling method was used to collect silver pompano. The intensity and prevalence of the P. hollisae ectoparasite worm that infested the silver pompano (Tracinotus blochii) in Lampung waters were the main parameters observed. Physical and chemical parameters are used as supporting parameters in this study. In the light category, the P. hollisae ectoparasite worm that infested silver pompano from Lampung waters had an intensity value of 1.38 individuals/head. The prevalence of P. hollisae worms in silver pompano (Trachinotus blochii) in Lampung waters was 86.7 percent in the usual category.
