Hubungan panjang-bobot dan faktor kondisi ikan selangat dianalisis dari ikan contoh yang dikumpulkan dari nelayan pada Juni hingga Agustus 2022 di Pantai Senggarang, Tanjungpinang. Penelitian bertujuan untuk menentukan pola pertumbuhan dan faktor kondisi ikan selangat. Sebanyak 422 ekor ikan contoh diukur panjang baku (mm) dan ditimbang bobotnya (g). Hasil penelitian menunujukkan bahwa nilai b sebesar 3,04 yang mengindikasikan pola pertumbuhannya isometrik. Nilai faktor kondisi berkisar pada 0,84 hingga 1,04. Pola pertumbuhan dan faktor kondisi tidak konstan, bervariasi musiman, berkait dengan banyak faktor seperti siklus reproduksi, ketersediaan makanan, dan faktor lingkungan dan habitatnya.

A total of 106 fish species belonging to 46 families and 12 orders were captured by beam trawl, fyke-net, and trap in wet and dry seasons. Perciformes was dominant and all of niche habitat inhabited by fish. The diversity of fishes was related with mangrove ecosystem around the Bintuni Bay. Fish communities divided into seven groups according to bioecological category and the group of marine-estuarine species was dominant. Spatial and temporal distributions of fish were varying related to aquatic environmental heterogeneity. A hypothetical trophic web was built based upon the different types of food resources used by each group of fish. Complexity of food web shows that estuary of Bintuni Bay is the feeding ground for many fish species.

The purposes of this study were to identify food item and determine the feeding habit of the javelin grunt in The Pabean Bay, West Java. Fishes were collected monthly from June to December 2016 using gill nets and trap nets. Observation food is in vitro by conducting an examination of the stomach and the intestines of an example and refer on the books of the identification by Carpenter and Niem. Analysis of fish diet includes index of relative importance, niche breadth, and niche overlap. Fishes were grouped into three groups based on the size length. The result showed that the javelin grunt was crustacivore. Generally, the diet of javelin grunt consists of Acetes sp., Penaeus sp., Portunus sp., Clupeid, Ambassid, Sciaenid, Gobiid, Sillaginid, and unidentified organisms. Penaeus sp. was the main food and could be found on each size of group in monthly observat...

Ikan ditangkap dengan jaring insang berlapis, jaring udang, dan sero setiap bulan dari April 2016Maret 2017. Komposisi makanan dan strategi makan dianalisis dengan IRP (Indeks Relatif Penting) dan metode strategi makan modifikasi Costello. Ikan Gobiidae yang tertangkap selama penelitian berjumlah sembilan spesies, yaitu Acentrogobius caninus (dengan kisaran panjang total 46115 mm), Acentrogobius cyanomos (49108 mm), Boleophthalmus boddarti (95189 mm), Glossogobius aureus (70210 mm), Oxyurichthys tentacularis (88130 mm), Parapocryptes serperaster (112198 mm), Paratrypauchen microcephalus (100150 mm), Pseudapocryptes elongatus (88190 mm), dan Taenioides cirratus (160 mm). Berdasarkan analisis makanan, ikan A. caninus, A. cyanomos, dan G. aureus dikelompokkan ke dalam ikan krustasivora, sementara ikan B. boddarti, P. serperaster, P. microcephalus, dan P. elongatus termasuk ikan pemakan fitobentik. Ikan A. caninus, G. aureus, dan A. cyanomos memiliki strategi makan spesialis dengan menu makanan utama berturut-turut adalah Metapenaeus sp. Metapenaeus sp., dan Acetes sp.
