This study aims to compare the income of fishermen before the COVID-19 pandemic and during the COVID-19 pandemic in Merauke Regency, as well as to examine the problems faced by fishermen during the COVID-19 pandemic in Merauke Regency. This research was conducted from June to July 20121 with the research locations being Lampu Satu beach in Samkai village, Merauke district and Kumbe beach in Kumbe village, Malind district. These two locations were chosen because they are the centers of the largest fishing population in Merauke Regency. Primary data collection using interview techniques, to 40 respondents who were selected by purposive sampling. Each of the 20 respondents in Lampu Satu waters in Samkai sub-district, Merauke district and 20 respondents in Kumbe waters in Kumbe village, Malind district. The research data was analyzed statistically by looking at the trend and time series of fishermen's income in Merauke Regency. Based on the results of research and discussion, it was concluded that the Covid-19 pandemic had an impact on the income of fishermen in Merauke Regency, both for ship owners, captains/captains, crew members (ABK) and for collectors/collectors of the catch. The impact given is in the form of a decrease in income obtained by fishermen by 58%. The decline in income was caused by constraints in marketing the main catch, namely fish bubbles which became an export commodity abroad during the total lockdown of airport and port access in Papua Province from March to June 2020. The decline in income was also caused by the increase in the number of operational costs in activities. arrests such as the cost of vitamins, medicines, masks and medical tests if needed.

Abstract

This research aimed to determine the size structure, length-weight relationship, growth, and mortality of kuro fish (Eleutheronema tetradactylum) that landed on Nusantara Fishery Harbour, Merauke District. The samples were taken off in August-October 2022 at Nusantara Fishery Harbour, Merauke District. The metusedsing was a purposive sampling method. The measured data was the total length and weight body of kuro fish. The size structure and length-weight relationship of kuro fish were analyzed using Microsoft Excel. Meanwhile, the growth and mortality were analyzed using the FISAT II application. The result analysis shows that the range of E. tetradactylum total length landed on Nusantara Fishery Harbour is 430 – 1030 mm with a weight range of 92 – 3613 grams. The length-weight relationship of E. tetradactylum has the allometric negative growth pattern with equation W = 0,0016L2,1167 in August, W = 0,0017L2,1134 in September, and W = 0,0017L2,1077 in October. The analysis of E. tetradactylum’s growth parameter shows the value L∞ = 1053 mm, K = 0,51/year, and t₀ = -0,1201 year. The result mortality analysis of E. tetradactylum shows the total mortality (Z) was 0,78/ year, natural mortality was 0,43/year, fishing mortality (F) was 0,35/year, and exploitation rate was 0,45/year.
