Abstract

ABSTRACTIn general, fisheries in Indonesia is still dominated by small-scale fisheries, one of themis the purse seine fishery based in Tamperan Fishing Port. This study aims to determine aspects of purse seine fishery based on Tamperan Fishing Port such as vessel size and fishing gear, FADs , fishing ground and catches. The study was conducted in 2012 in Tamperan Fishing Port with measurement methods and direct observation and interviews with owners, skippers and crew. The results showed that the vessel of small-scale tuna purse seine fishing based in Tamperan Fishing Port have tonnage between 28-45 GT and made of wood with length 17.21-28 m, width 6-7 m, and depth 2-3 m. Nets is used have length between 250-300 m and width 8-10 m. Fishing ground is FADs at coordinates 10º-12º S and 100º-110º E, 60-100 miles from the Pacitan Bay with distance to the location of FADs about one day. The catch is dominated by skipjack about 57.27%, followed by scad26.31% and juvenile yellowfin 10.05%.Keywords: Purse seine, small scale tuna fisheries, Tamperan-------ABSTRAKSecara umum, perikanan tangkap di Indonesia masih didominasi oleh usaha perikanan skala kecil, salah satunya adalah nelayan pukat cincin yang berbasis di PPP Tamperan. Penelitian ini bertujuan untuk mengetahui aspek penangkapan perikanan pukat cincin yang berbasis di PPP Tamperan berupa ukuran kapal dan alat tangkap, rumpon, daerah penangkapan dan hasil tangkapan. Penelitian dilakukan pada tahun 2011 di PPP Tamperan Pacitan dengan metode pengukuran dan pengamatan langsung di lapangan serta wawancara dengan nelayan pemilik, nakhoda dan awak kapal. Hasil penelitian menunjukkan bahwa armada pukat cincin perikanan tuna skala kecil yang berbasis di PPP Tamperan memiliki ukuran tonase antara 28-45 GT dan terbuat dari kayu dengan ukuran panjang antara 17,21-28 m, lebar 6-7 m, dan dalam 2-3 m. Jaring yang digunakan memiliki panjang antara 250-300 m dan lebar 8-10 m dengan menggunakan rumpon. Daerah penangkapan berada pada koordinat 10º-12º LS dan 100º-110º BT dan berjarak sekitar 60-100 mil dari Teluk Pacitan dengan lama perjalanan menuju lokasi rumpon sekitar 1 hari. Hasil tangkapan didominasi oleh cakalang sebesar 57,27%, diikuti oleh layang 26,31% dan yuwana madidihang 10,05%.Kata kunci: Pukat cincin, perikanan tuna skala kecil, Tamperan

Abstract

Research on the reproductive biology of fish can provide information on spawning frequency, spawning success, spawning time, and size at first maturity. This research aimed to determine the reproductive biology of common dolphinfish (Coryphaena hippurus Linnaeus, 1758) landed at the fish landing site (PPI) Kedonganan, Badung, Bali. Sampling was conducted in May - September 2018. A total of 42 female common dolphinfish with length ranged between 41-110 cm FL were obtained from hand-line fishery based on FADs. Ovaries were prepared using the paraffin method and Harris Haematoxylin-Eosin staining for histological observation. The results showed that the gonad maturity level in adult females was: spawning (38.10%), spawning capable (35.71%), regressing-potentially reproductive (4.76%), regressed 1 (2.38%), regressed 2 (2.38%), and regenerating (2.38%). Immature female: immature (9.52%) and developing (4.76%). Oocyte diameter ranged between 43,20 – 864,66 µm with an average of 430,99 µm. Fecundity in fish size 49-75 cm FL ranged from 30,720-433,080 eggs / fish with an average of 129,594 eggs / fish. The difference in the level of oocytes in the ovaries at the same time showed that female common dolphinfish in the southern Bali waters has an asynchronous ovary development and indeterminant fecundity with multiple spawning strategies and size at first maturity (Lm50) was 43.2 cm FL. Keywords: common dolphinfish, gonad histology, size at maturity

Abstract

Understanding the vertical distribution of large pelagic fish, swordfish in particular, could improve our knowledge on its fisheries strategy, management and resource conservation. However the methods often require expensive tools and resources, which probably most scientists from the development countries couldn’t afford. Thus developing model on the diel vertical movement behavior of swordfish using number of hook between float (HBF) and complete-set temperature and depth recorder (TDR) data could be an alternative. In general context, capture depth distributions are a good indicator of the natural depth distribution of the fish if the entire depth range of the species is targeted by longline gear. The proposed sinusoidal model suggested that swordfish showed a diel pattern in depth distribution, marked by remained in the surface and mixed layer waters at night and dived into deeper waters during the day. Keywords: swordfish, behavior, HBF, TDR, sinusoidal model
