Abstract

ABSTRACT This study aims to determine the level of diversity of fish caught by fishermen on the coast of the Desa Mendalok. The study used purposive random sampling method by selecting random fishermen based on the fishing gear used, those were 2.5 inch trawl, 7 inch trawl and 3 layer trawl. The study was conducted weekly from September to November 2018. The data collection includes primary data and secondary data. Primary data was obtained from catch fishermen,  namely the number and fish species. Secondary data include mendalok village profile, fisheries data marine and fisheries agency of of west Kalimantan Province and rainfall and tides from Meteorological, Climatological and Geophysical Agency. The result showed that there were 35 species fish caught belonging 23 families. The result of this study showed gelama panjang fish (Otolithes ruber), tudung tempayan (Drepane punctata), and bulu ayam fish (Thryssa setirostris) for high frequency fish caught. Sciaenidae and Dasyatidae were the dominant family.  Keywords : Type composition, Trawl, Sciaenidae, Dasyatidae

Abstract

This research focuses on the bioecology of Asian Redtail Catfish (Hemibagrus nemurus) in the downstream of the Kapuas River, Radak Village, Terentang Sub-district, Kubu Raya District. It was conducted from June to September 2020. It aims to identify the relationship between biological aspects including distribution and food habits with the habitats of catfish in the downstream of Kapuas River. It used a purposive random sampling method by selecting the research location based on differences in the environmental setting. The research area was divided into three stations consisting of Station I, which is far from residential areas and bordering secondary forest. Station II is the meeting point of Kapuas River and the Creek of Radak River. Then, station III is close to residential areas. The distribution of catfish could be found in all three stations at a certain time with the highest abundance at station II. The food habit of catfish was considered carnivorous with a length of RGL <1 with the main food of shrimps with an IP percentage of 41.55%, followed by fish and insects as complementary foods with an IP percentage of 27.45% and 19.6% respectively. The ISC value of catfish ranged from 0.8-1.9%. The water condition in the downstream of the Kapuas River is still balanced for the life of catfish.

Abstract

ABSTRACT The beardless barb (Anematichthys apogon) is one of the dominant fish species in the Telabang River, Subah Village, Tayan Hilir, Sanggau Regency. However, there is little biological information, one of the important aspects of reproduction to help plan fisheries management. The main objective of this study was to determine some aspects of the reproductive biology, namely sex ratio, growth pattern, and fecundity. Biweekly sampling was conducted by using purposive sampling method from Juli to September 2018. The result showed that significant sex ratio was 2,2 : 1 (male : female). The significant different of sex ratio from the total length structure are fish measuring 60-69, 70-79, 80-89, 100-109, 110-119, and 120-129 mm. The relationship of total length and total weight was showing positive allometric of growth pattern for males (b = 3,44) and the combination of males and females (b = 3,41), meanwhile found the isometric pattern of growth for females (b = 3, 07). The total fecundity was about 430-1.703 eggs and relative fecundity is about 42 to 199,65 eggs/gram total weight of fish. The relationship between total fecundity with length and total weight showed that total fecundity had no relationship to the length and total weight of the beardless bard.  iiKeyword : Reproductive Biology, Fecundity, Allometric, Isometric.

Abstract

One of the fisheries commodities that are currently the mainstay of Indonesia's exports is lobster ( Panulirus spp ). Lobster is a very potential fishery product, because lobster has a high selling value and high nutrition. This research was conducted for four months, from December 2019 to March 2020 and the object under study was the pakistani lobster (Panulirus polyphagus).This research was conducted to estimate pakistani lobster stock in the beach area of Sebubus Village, Paloh District, Sambas Regency. Based on the results of the research, the ratio of male to female sex was 2.1: 1. The relationship between length and weight produces a negative allometric growth pattern. The growth rates of male and female Pakistani lobsters were 103.95 mm and 98.4 mm. The growth coefficient of  male and female lobsters is 0.51 per year and 1.01 per year. Natural mortality of male and female lobsters is 0.66 per year and 1.05 per year and lobster mortality is caused by natural mortality factors. The exploitation rates for male and female lobsters are -0.13 per year and  0.39 per year, so the exploitation of lobsters is under fishing because the E value is below 0.5. The pattern of recruitment in male lobsters has one peak, namely in March and in females there are three peaks, namely in Juli, September and October.
