Abstract

Sorong City is located in a strategic area in Southwest Papua Province. The development of the fisheries sector in Sorong City is increasing, and various efforts are being made by the Regional Government, one of which is to support Fish Landing Base (PPI) facilities that are needed by fishermen as a place to land their catch, which is then purchased by collectors or consumers. The types of fish that are generally landed in PPI Sorong City are generally large, medium, and small pelagic fish. Yellow trevally (Selaroides leptolepis), known locally as Oci fish, is one of the most popular fish types in Sorong. This study aimed to determine the relationship between the length and weight of yellow trevally (Selaroides leptolepis) as a basis for fisheries resource management. The research was conducted at PPI Sorong City in July, August, and September 2022. The samples used were obtained from Selar Fish landed in PPI Sorong City, which were then measured and weighed. The results obtained in July were b= 2.32, which was negative allometric; in August, b= 2.60, which was negative allometric; and in September, b= 3.10, which was positive allometric.

Abstract

The development of mirror carp (Cyprinus carpio) farming in Indonesia has progressed very rapidly, as can be seen by the increasing number of varieties of mirror carp produced from various regions with their respective specifications and advantages. Along with the need for carp that are more resistant to environmental changes and disease attacks, the development of the Majalaya carp variety subsequently produces Mantap carp fish that are disease-resistant, and growth in the growth segment is faster. The aim of this study was to disseminate technical information on Mantap fish carp culture to the public so that it can be used as a reference source for the community, especially for cultivators who are interested in developing this fish. In this study, primary and secondary data were collected. Based on the results of a fecundity study, one female broodstock produced 104.496 kg broodstock-1, the average percentage of egg fertilization (FR) was 89,64%, the average hatching rate (HR) was 61,37%, and the average survival rate (SR) until the size of the seed size 2-3 cm reaches 60%.

Abstract

Foreign fish in waters that are not their habitat can have a major impact on the balance of the ecosystem. One of the foreign fish living in Indonesian waters is the red devil foreign fish. The presence of red devil foreign fish (Amphilophus citrinellus) in Indonesian waters reduces biodiversity and is harmful to aquatic ecosystems. This study aimed to assess the negative impact of Amphilophus citrinellus in the Sanguling Reservoir, West Bandung Regency. This study used the desk study method and direct observations in the field. Data were collected using literature review and interview methods. The finding of red devil foreign fish species with the Latin name Amphilophus citrinellus in the Sanguling Reservoir provides information related to the negative impact of invasive foreign fish. This information can be used as a basis for developing regulations that are focused and directed towards invasive species, as well as to increase the active role of several sectors, such as research, and developing mitigation of the impacts caused by invasive species so that the Sanguling Reservoir ecosystem is maintained.

Abstract

Many farmers and fishermen from the north coast of Java Island (Pantura) migrated to the south coast of Java to try their luck as fishermen in the Cilacap Ocean Fisheries Port (PPSC). The urbanization of Pantura residents to Cilacap has been ongoing for more than 50 years. This study aims to determine the contribution of Pantura residents to the capture fisheries sector in the PPSC. Data were collected through observation, interviews, surveys, and documentation. Data analysis used descriptive analysis with reduction and interpretation as well as ANOVA and simple linear regression analysis. Based on the survey results, 90% of respondents stated that the reason for Pantura residents to migrate to Cilacap was to increase their income. According to 93.3% of respondents, their arrival at PPSC contributed to the capture fisheries sector in the Cilacap Regency. The results of the ANOVA test show a significance of <0.05, which means that there is an influence from the arrival of Pantura residents in increasing capture fishery production in PPSC. The correlation between the arrival of Pantura residents in PPSC and the increase in capture fishery productivity was 43.5%, with an influence level of 18.9%. Thus, the role of Pantura residents is very important in increasing capture fishery production in Cilacap.

Abstract

This study aimed to determine the type, composition, and abundance of zooplankton in the waters of Kampung Nafri. Zooplankton were identified using zooplankton sample identification guidelines, and zooplankton abundance analysis was performed using the Sedgewick Rafter. Purposive sampling was used in this study. Zooplankton sampling was carried out horizontally on the surface of the water using a plankton net which was carried out in the morning around 08:00 - 10:30 WIT at 3 stations. Sampling at each station was done 2 times repetition and the water parameters were done 3 times repetition. In situ measurement of water quality parameters, such as salinity, pH, current speed, and temperature Based on the identification results, there are 11 types of zooplankton that inhabit the waters of Kampung Nafri. The highest value of zooplankton species composition in Nafri Waters was Naplius sp., which was 63%, and the lowest was Temora sp. and Corycaeus sp. by 1%. The highest abundance of zooplankton species in Nafri Waters was Nauplius sp. (Copepoda larvae), with a total abundance of 9,900 ind/l, and the lowest was Corycaeus sp. and Temora sp., with a total abundance of 200 ind/l.

Abstract

Kolaka Regency is one of the fisheries producers in Southeast Sulawesi Province. The economic value of capture fisheries in Kolaka Regency also continues to increase from year to year. Unfortunately, this increase is not followed by an improvement in the economy of small-scale fishermen. Many factors influence this. One of them is the still high practice of using simple fishing gear and the management of fisheries businesses that are not yet qualified. Lawulo Village has people whose main livelihood is fishing. In general, they use gill nets in their capture fisheries business. This study uses multiple linear regression analysis intending to know the factors that influence the income level of gillnet fishermen. The data used is primary data obtained from interviews with fishermen. The results showed that four factors significantly influenced the income level of basic gillnet fishermen, namely age and education level. The variable number of family dependents and business experience did not significantly affect the income received by fishermen.
