Abstract

Communities in Pulau Banyak District on average work in the fisheries sector as fishers. Pulau Banyak fishers take advantage of the potential of captured fisheries as their main source of income. The living conditions of fishers are often classified as a marginal group close to poverty. This study aims to examine the socio-economic conditions of fishers in the Pulau Banyak District of Aceh Singkil. The method used is to conduct a field survey using a questionnaire (interview). The location of the research was in Pulau Banyak District, Aceh Singkil Regency. The results of the study show that the social conditions of the Pulau Banyak people work as fishers with a low level of education, at most equivalent to elementary school. The economic condition of the fishers on Pulau Banyak is seen based on their main income and also other income sourced from side income and the income of family members who help fishers. The main source of income for fishers is an average of IDR 1,000,000-1,500,000 per month with an average trip of 6 times a week or 24 times a month with catches of 8 types of fish. While the pattern of fish marketing, the average fishers as much as 64 percent choose to sell to bench shops. The government has an important role in monitoring the marketing pattern of fishery products and implementing policies for optimal and sustainable utilization of fishery resources.

Abstract

The hearing level of fishermen in the Lembeh Strait out of 11 fishermen, there are only 2 fishermen whose hearing is still normal. This is likely the effect of a plain exhaust modification and does not use a muffler. The muffler acts as a sound transmission damper when the exhaust gases exit the engine. The objectives of this study are as follows: 1) redesign of the engine exhaust of the pakura boat; 2) analyze the relationship and influence of rotation per minute with laboratory-scale noise levels; and 3) analyze the relationship and influence of rotation per minute with field-scale noise levels. The method used in this research is experimental laboratory and field, comparising one control group and three treatment groups. The results obtained are that there are three types of redesigned exhausts equipped with mufflers. The most effective exhaust for reducing noise levels is exhaust type B, with a range of values between 79-93 dB in laboratory scale and 90-102 dB in field scale.

Abstract

The decline in seahorse populations in the wild due to high fishing activity and habitat degradation prompted the inclusion of all seahorse species in Appendix II of CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) in 2002. By being included in Appendix II of CITES, data and information on the abundance of seahorse populations become crucial as the basis for determining the quota for fishing and trade. Estimating population abundance of seahorse requires knowledge of habitat area, which can be modeled using the MaxEnt (maximum entropty). In this study, an estimation of the abundance of seahorses was carried out in the waters of Sebong Bay, Bintan Island. MaxEnt modeling was implemented with data on seahorse presence locations and environmental parameter maps consisting of chlorophyll-a as primary productivity parameter, benthic habitat as habitat type parameter, and dissolved oxygen, salinity, and pH as physiological parameters. From this model, the value of the area of suitable habitat for seahorses is 54,6 ha, while the density of seahorse in this area is 60 ind/ha, so it can be determined that the abundance of seahorses in the Sebong Bay is 3.276 individuals. Therefore, seahorse population in Sebong Bay is critically endangered since it is below the number of individuals that required to prevent the loss of quantitative genetic variation in a species.

Abstract

The most attention issue of sustainable fisheries management is related to the availability of catch and fishing efforts data with the spatio-temporal distribution. The monitoring data plays important to evaluate the fish stock status and fishery dynamic in the waters. As dependent-fishery data, logbook data is a reliable data source for estimating the utilization rate of fish resources and designing effective regulation tools in fisheries management areas. This study aims to analyze catch composition, spatial and temporal distribution, and productivity (catch per unit effort) of small-pelagic purse seine fisheries in the Java Sea using fishing logbook data. The result shows the highest It was found that the catch composition of small pelagic purse seines was dominated by longtail tuna/kawa-kawa, scad (Decapterus spp.), and sardinella fimbriata with the highest catches annually occurring in September 2021, March 2020, and November 2019. However, the highest productivity was achieved in September 2021, May 2020 and June 2019, namely 1,290 kg/setting/day, 1,700 kg/setting/day, and 1,660 kg/setting/day, respectively. Regarding spatial distribution, the highest productivity was in the northern and central parts of the Java Sea and the southern parts of Kalimantan.

Abstract

The increase in aquaculture production must be accompanied by effective and efficient feed, thus requiring innovation to obtain the appropriate feed ingredients. This research aims to determine the effect of maggot meal and commercial eel feed on the growth, protein digestibility, and production cost of eel (Anguilla bicolor bicolor) aquaculture. Eels were reared in 15 aquariums measuring 60 × 40 × 40 cm, equipped with water filters, with five treatments and three replications. The treatments consisted of maggot meal + eel feed in the following proportions: A1 (0% + 100%), A2 (25% + 75%), A3 (50% + 50%), A4 (75% + 25%), and A5 (100% + 0%). The feed was given twice a day, morning and afternoon, according to the requirements. Data on growth rate and feed efficiency were collected every two weeks, while protein digestibility and production cost were calculated at the end of the 60-day study period. Treatment A2 showed a daily growth rate of 1.218±0.409%, which approached the growth rate of the commercial feed treatment (A1). Treatment A5 had a growth rate of 0.309±0.218% per day, while treatment A1 had a growth rate of 1.440±0.364%. The best feed conversion ratio (FCR) in each phase was obtained in treatment A1, with a value of 1.862±0.086. The highest FCR was found in treatment A5, with a value of 6.455±1.158 in each phase. The best feed efficiency was observed in treatment A2 at 82.79%, while the lowest digestibility was in treatment A4 at 34.88%. The digestibility of feed in treatment A2 was the highest at 58.42%. According to the research findings, the production cost per kilogram of eel was more cost-effective and required less time in treatment A2, with a feed cost of Rp 105,000/kg. The utilization of a combination of maggot meal and commercial feed shows potential as a feed that can be used to enhance growth rate.
