Abstract

ABSTRACT It has been widely known that the Indonesian enormous fish diversity has reached over 300 species of both breams and sea breams (DKP, 2007). The diversity itself, based on LIPI (2010) has contained about 4000-6000 species all over the territorial waters. There are over 2917 species of breams identified in South East Asia (Kottelat et al 1993). This study is aimed at investigating the diversity of species of hauls of the trawl fishermen on fish disembarkation in Muara Kakap. The method of the study is purposive random sampling with random interviewee. The data was collected as primary and secondary data. The primary data was the fishermen hauls including the number and type. The secondary data was the number of regular hauls, annual hauls, decreasing hauls, the caught-hauls data from Marine and Fisheries Office of West Kalimantan Province as well as the data of rainfall and tide from BMKG. This study was conducted on March until May 2019. Based on the research findings, obtained 26 species of 21 families. 5 species of daily hauls are gelame ketupat (Nibea soldado), ikan selangat (Anodotosma chacunda), ikan gelame bungketo (Pennahia anea), ikan belanak (Mugil dussumieri). The biggest of family Scianidae were found 3 species while Lutjanidae 2 species. The diversity index during the study (H"™) was 2,47 classified as average while domination index (C) was 0,12 which means none of the species are dominating.

Abstract

ABSTRACTInformation about the stock of mangrove crabs (Scylla tranquebarica) in West Kalimantan is still very minimal, especially in Kubu Village, Kubu District. The purpose of this study is to estimate the stock of S. tranquebarica the catch of the fishermen from the Village of Kubu sub-District, Kubu Kubu Raya District of West Kalimantan Province. The method used for sampling was the Census method in which the samples to be observed were all the catch of mangrove crabs in 2 (two) collectors in Kubu Village. Sampling of S. tranquebarica was carried out at once time interval in biweekly for 4 (four) months. This study was conducted in September-December 2018. Based on the results of the study, S. tranquebarica which was caught during the study were 413 crabs, in which male crabs were caught of 301 crabs and female crabs of 112 crabs. The distribution of the frequency width of the carapace of male crabs observed ranges from 95-60 mm with a weight of 185-1279 grams, while the females range from 100 to 150 mm and the weight of the 214-962 grams. The relationship of the width and the weight of S. tranquebarica male is allometrik positive, the female is isometric. The width of the asimptotik (L∞) S. tranquebarica males 242 mm, females 165 mm, coefficient of growth (K) male 0.15 per year, the female 0,39 per year. The natural mortality of males 0.236 females 0.492 male arrest mortality of 0.421 females 0.483. The exploitation rate of male crabs is 0.640 per year while females are 0.495 annually which means that males crabs have been over-exploited while females have not been over-exploited.
