Abstract

Ikan layang merupakan salah satu komoditas ekonomis penting di Sulawesi Selatan. Penelitian ini bertujuan untuk mengetahui beberapa aspek biologi reproduksi ikan layang meliputi nisbah kelamin, Indeks Kematangan Gonad (IKG), Tingkat Kematangan Gonad (TKG), ukuran pertama kali matang gonad dan fekunditas ikan layang deles yang tertangkap menggunakan bagan perahu di perairan Kabupaten Barru. Pengambilan sampel dilakukan pada bulan Juni hingga Oktober 2013 di Kelurahan Sumpang Binangae yang merupakan fishing-base nelayan penangkap ikan layang deles. Analisis sampel dilakukan di Laboratorium Biologi Perikanan, Jurusan Perikanan, Universitas Hasanuddin, Makassar. Nisbah kelamin dianalisis menggunakan uji chi-kuadrat, TKG ditentukan secara morfologi, IKG dihitung menggunakan metode perhitungan (Johnson, 1971), ukuran pertama kali matang gonad diperoleh dari ukuran pertama pada TKG III dan fekunditas menggunakan metode gravimetric. Ikan layang deles yang diperoleh selama penelitian sebanyak 213 ekor, dengan nisbah kelamin jantan : betina adalah 2,33 : 1,00.  Secara statistik, nisbah kelamin ikan jantan dan betina bukan 1 : 1 atau dalam keadaan tidak seimbang (α = 0,05 ; X2 hitung = 59,6082;  X2 tabel = 9.488; db = 4).  Ikan layang deles pada perairan Barru diperoleh TKG I sampai V dengan IKG 0.0503– 4.4667 % untuk ikan jantan dan 0.2501 – 7.6677 % untuk ikan betina. Persentase ikan layang deles matang gonad tertinggi ditemukan pada bulan Juli dan September, baik untuk ikan jantan maupun ikan betina, sementara pada bulan Oktober ikan yang tertangkap didominasi ikan yang belum matang gonad. Ikan layang deles jantan matang gonad pada ukuran 142 mm dan betina pada ukuran 128 mm dengan fekunditas berkisar antara 1.512 - 34.875 butir.

Abstract

his research was conducted in November to December 2012 which aimed to estimate thepopulation dynamic of mackerel fish through their age-group, growth, mortality, and yield perrecruitment. Samples were taken from the waters of sub district of Panyula, in the district of EastTanete Riatang, in Bone Region. Age-group was measured using Bhattacharya method with thehelp of Fish Stock Assessment Tools II (FISAT II) software. Growth and natural mortality weremeasured by applying the equations of Von Bertalanffy and Empiris Pauly (respectively). Whereastotal mortality as well as yield per recruitment were estimated by applying Beverton and Holdequation; and catch mortality was estimated by applying the equation of Z=F+M. Results showedthe average total length of 849 mackarel fish that was 121-295 mm. They were divided into 4groups with 306.35 mm asymptotic length, 0,33 growth rate coefficient and theoritical age of 0.0294year. Natural mortality rate, total and catch mortality, and exploitation rate were 0.3672per year; 2,4358 per year, 2,0687 per year and 0.8493 (respectively). This indicated that an overcatch had occurred due to the higher catch mortality compared to the natural mortality as well asthe yield per recruitment, i.e. 0.0865 gram/recruitment. Keywords : Population dynamic, mackerel fish, Bone Strait.

Abstract

White-spotted spinefoot, Siganus canalicullatus (Park, 1797) is one of the most economically importantherbivorous fish captured along the coast of Selayar Islands. The present work was undertaken to assess thelength-weight relationship and Fulton's K condition factors of this fish caught in the waters of the northern coastof Selayar Islands District. Those parameters were calculated separately for both sexes. A total of 498specimens of S. canaliculatus consisting of 265 males and 233 females were randomly collected on a monthlybasis between January and June 2015 from local fishermen using gill nets of various mesh size in the coastalwaters of Desa Barat Lambongan, Kecamatan Bontomatene, northern part of Selayar Islands District. The fishwere brought to the laboratory and, after washing, their total length (L) was measured to the nearest 1 mm usinga fish measuring board and the total body weight (W) was recorded to the nearest 0.01 g using an electronicbalance. Each fish was then cut open and the sex were recorded. The length-weight relationships of males andfemales can be expressed as log W = –4.4220 + 2.7772 log L for males, indicated hypoallometric growthpattern; and log W = –4.6840 + 2.9022 log L for females, indicated isometric growth pattern. Overall, conditionfactor values were higher in males than in females.Keywords: condition factor, length-weight relationship, Selayar Islands District, Siganus canaliculatus, whitespottedspinefoot

Abstract

The skipjack tuna (Katsuwonus pelamis) resource in Bone bay has long been exploited, but information about the sustainable potential of this fish resource in Bone bay waters is still very limited. The aim of this research is to estimate potential of fish resources that include catch per unit effort (CPUE ), the maximum sustainable yield (MSY), optimum effort, exploitation rate and total allowable catch (TAC) of skipjack tuna in the waters of Bone bay. This study uses time series data, namely annual data from the fisheries statistics report at Marine and Fisheries Service, South Sulawesi Province from 2006-2015. The method used to estimate the potential of fish resources in this study is the surplus production method with the Schaefer model. The results showed that the average production and standard efforts in the 10-year period were 14689.7 tons and 914 standard units respectively. The estimation results obtained MSY and optimum effort per year are 22561.4 tons and 1730 standard units, and allowed catches (TAC) of 18049.2 tons per year. The level of exploitation of skipjack tuna resources in the waters of Bone Bay does not over exploited every year except in 2017.Keywords: potential of fish resources, skipjack tuna (Katsuwonus pelamis), MSY, TAC, Bone bay

Abstract

Penelitian ini bertujuan untuk menganalisis diferensiasi morfologi yang terjadi di antara stok ikan kakap putih, barramundi (Lates calcarifer Bloch, 1790) di perairan pantai Kabupaten Bone, Wajo, Takalar, dan Kalimantan Utara. Diferensiasi karakter morfometrik dianalisis menggunakan fungsi dikskriminan. Hasil penelitian menunjukkan bahwa ikan kakap putih dari perairan Teluk Bone, Selat Makassar dan pesisir Pantai Sekatak Kalimantan Utara bersifat monophyletic. Aliran gen dan migrasi di antara populasi atau stok ikan kakap putih sangat terbatas atau hampir tidak ada. Stok ikan kakap putih di pesisir pantai Desa Akkotengeng Kabupaten Wajo dan stok di pesisir pantai dan daerah aliran sungai (DAS) Sungai Saro Kabupaten Takalar melakukan rekruitmen sendiri. Terdapat satu individu ikan kakap putih di perairan pantai Siwa Kabupaten Wajo dan Cenrana Kabupaten Bone (kedua stok berlokasi di Teluk Bone) yang memiliki fenotipe (morfologi) yang mirip dengan ikan kakap putih di perairan pantai Bulungan Kalimantan Utara. Analisis kontribusi 15 karakter morfometrik terhadap fungsi kanonik menunjukkan bahwa karakter yang menjadi penciri di antara stok adalah tinggi badan, caudal peduncle, dan diameter mata. Hasil discriminant function analysis (DFA) menunjukkan bahwa terdapat tiga populasi lokal yang signifikan berbeda secara fenotipe, sehingga dalam pengelolaannya dibutuhkan manajemen yang berbeda.Kata kunci: Asian seabass, barramundi, karakter morfometrik, Lates calcarifer
