Abstract

The study on the biological aspects of Charybdis hellerii (A. Milne-Edwards, 1867) in the world and Indonesia were very limited. This study aims to measure the sex ratio, gonad development, carapace width and body weight relationship, condition factor, the first size sexual maturity, and fecundity. This study was conducted from July to September 2020 in the western of the Tiworo Strait, South Konawe, SoutheastSulawsei. The C. hellerii samples were bycatch of the blue swimming crab using collapsible traps. The results of sex ratio based on a period show significantly different (p<0,05) with a ratio of 1:1, except Agust. Gonad development males and females dominated mature, while ovigerous females dominated immaturely. The carapace width and body weight relationships between males and females exhibited a strong and positive relationship (r>0,75) with a pattern of growth allometric negative. Condition factor males significantly different (p<0,05) from females and ovigerous females. The first size carapace width sexual maturity male and female respectively were 61,86 mm and 48,90 mm. Fecundity of C. hellerii ranging from 18706 to 506876. These data on biological aspects can contribute to the sustainable management of C. hellerii in the Tiworo Strait.

Abstract

This study aims to determine the operating techniques of bottom longline fishing gear and determine the added value created by bottom longline fishing gear. This research was carried out in Bahari Village, Sampolawa District, South Buton Regency in July 2022. The method used in this study was the census method. Data collection was carried out through interviews, observation, documentation and literature studies. Data analysis uses the added value formula, namely NT=G+Pt+Pj+π. The results of the study concluded that the bottom longline fishing technique in Bahari Village was to go to the fishing location, place bait on each hook, release the bottom longline at a depth of 10-20 meters with fishing gear lengths varying from 900-1100 meters with a total of ±200 hooks for each fisherman and 3 units of buoys and left in the sea for 2-3 hours, as well as hauling (lifting fishing gear). This fishing gear is operated at low tide. The added value created by bottom longline fishing gear, the lowest value is Rp913.000,-/trip and the highest is Rp1.351.000,-/trip and the average is Rp1.179.850,-/trip, the added value obtained from the sum of Salaries, Depreciation, Taxes and Profits

Abstract

This study aims to determine the factors that influence fishermen to sell their fish catch in outside of the Kendari PPS company. The population in this study were fishermen who sold their catch within the Kendari PPS company and outside the Kendari PPS company totaling 80 vessels with a size of 30 GT, sampled by accidental sampling to meet 35 respondents. The data collection techniques used were observation, interviews, and documentation from respondents which were then tabulated and analyzed using Multi Criteria Analysis (MCA) to achieve the research objectives. As a result, there are 6 factors that influence fishermen to sell their catch outside PPS companies, namely price, company provisions, facilities, sources of capital, completeness, and ease of access. Of the six factors, the price difference indicator appears as the most dominant factor influencing. Thus to be able to meet the number of fishermen who sell outside PPS, the main variable that needs to be considered is the occurrence of price differences.

Abstract

This study aims to determine the relationship between the time length for looping the net and pulling the corrugated rope on the production of purse seine fishermen in Kakenauwe village, Lasalimu district, Buton regency. The experiment was carried out from June to July 2021 in Kakenauwe Village, Lasalimu District, Buton Regency. The experiment used a random sampling technique with a total of 20 purse seine fishermen. The data collection process was carried out by means of observation, interviews, documentation, and literature studies. The data obtained were analyzed using the Cobb-Douglas formula and F test. The results of the analysis showed that the amount of production at the time length of setting and pulling the corrugated line in the purse seine fishing business from the calculation was strongly influenced by changes in the time length and the pulling of the corrugated line was 83.3 kg/minute. The second results showed that, based on the results of the f test the relationship between the length of time the net is encircled and the pulling of the crimped rope to the total production of purse seine fishermen simultaneously was significantly effect on the total production of purse seine fishermen because the calculated f value was more higher than the f table value (F table = 0.05 > 0.01)
