Abstract

This study aimed to map the oceanographic conditions and, based on that, to determine the favorable condition of skipjack tuna fishing ground in Fisheries Management Area (FMA) 713. This condition includes sea surface temperature (SST) and chlorophyll-a concentration. The primary data, such as fishing ground position and fish catch per trip, was collected by following the fishing operations that utilized pole and line (in Bone Gulf and Flores Sea) and purse seine fishing operations (in Makassar Strait). The secondary data, such as SST and chlorophyll-a, was derived from oceanographic satellite image data. The result showed that from January to August 2019, the skipjack tuna tends to occupy off shore areas where the sea surface temperature is between 29 - 29.5 oC and the chlorophyll-a density is between 0.10 to 0.15 mg.m3.

Abstract

This paper provides an explanation of the condition of phytoplankton in the estuary waters of the west coast of South Sulawesi. The study was carried out on four estuaries namely Tallo, Marusu, Polong and Battoe with spatial sampling from inside the estuary to the outside of the estuary. The results obtained were found in three classes, namely Bacillariophyceae class, Cyanophyceae class, and Dinophyceae class with 19 phytoplankton genera. With an abundance of phytoplankton ranging from 352 - 5304 cells / L, the highest abundance is in the Tallo estuary. Meanwhile, the highest diversity index (H ') was found in Tallo estuary and the highest dominance index (D) was in Tallo estuary. Parameters that characterize high abundance estuaries are nitrate and TSS.

Abstract

The first step to establishing appropriate broodstock management and conservation programs and to avoid decreasing genetic variability in this selective breeding program is the development of molecular genetic markers that can be used for evaluation of genetic stock determinations in gene flow rates. However, morphologically it is rather difficult to distinguish between one individual and another. The purpose of this study was to analyze genetic variation to prove differences in intrapopulated crabs. Small crab samples were collected from the district. Kaimana, West Papua. Morphological analysis was carried out by looking at differences in the color and pattern of white spots between one individual and another. The isolation of the crab CO1 gene was carried out by analyzing each individual after grouping it based on morphology. The results of the morphological analysis showed that males had seven color patterns and white carapace patterns while females had five color patterns and white spots on the carapace. However, there is little difference between morphology and genetics, especially in females, where the female is genetically divided into only two major groups. This indicates that there is information on phylogenetic relationships between individuals. The white spot on the carapace is genetically influenced so that it can be used to identify species or varieties, while the carapace color has not been shown to be influenced by the CO1 gene.

Abstract

Eel fish are traded until they are exported to foreign countries such as Japan. This research was conducted during October-November 2019 in Sopu Village Nokilalaki District Sigi Regency Central Sulawesi. The purpose of this study was to determine the production and income of Eel Fish and to analyze the marketing price and the factors that influence the marketing price of Eel Fish in Nokilalaki District Sigi Regency Central Sulawesi. The method used is a combination of qualitative and quantitative methods using the income formula and multiple linear regression formula. The results of this study are, the production of Eel Fish in October 2019 was 93 fish. The income from selling Eel Fish ranges from nominal Rp.600,000 to Rp. 2,500,000 per month. There are several factors that influence the marketing price of eel Fish they are, production costs, number of fish sold, distance of sales location, number of consumers, competitors, and basic income. There is a significant influence of the dependent variable (Marketing Price) with the independent variable (the six factors that influence). The significant influence percentage was 55.1% with the intertwined relationship seen from the value of R approaching 1 which was 0.742. Of all the factors, only the number of consumers (X4) significantly affected the marketing price of Eel Fish in Sopu Village Nokilallaki District Sigi Regency Central Sulawesi.

Abstract

This study aims to estimate the potential of fish resources which include catch per unit effort (CPUE), Maximum Sustainable Yield (MSY), optimum efforts, exploitation rates and total allowable catch (TAC) of Rabbitfish in Makassar waters. This study uses time-series data, namely annual data from the fisheries statistics report at the Office of Marine and Fisheries Service, South Sulawesi Province from 2007 until. 2016. The method used to predict fish resource potential in the study is the Surplus Production method referring to the Schaefer model. The results of the study showed that the average production and standard efforts in the 10-year period were 78.8 tons per year and 1304 standard units per year respectively. The estimation results obtained by MSY and the optimum efforts of rabbitfish per year were 104 tons and 1142 standard units, respectively and total allowable catches (TAC) are 82.979 tons per year. The level of utilization of rabbitfish resources in Makassar waters in the last three years has been overexploitation.
