Kegiatan budi daya ikan perlu dilakukan guna untuk memenuhi kebutuhan dan mencegah kepunahan, terutama yang bernilai ekonomis penting seperti ikan gurami. Tujuan penelitian ini menganalisavariasi padat tebar benih ikan gurami (Osphronemus gouramy Lac.). Penelitian dilaksanakan di Pusat Ikan Hias Mentaos Pokdakan Mina Satu Hati Jl. Mentaos Timur Rt.01, Rw03, Desa Mentaos, Kecamatan Banjarbaru Utara, Kota Banjarbaru.. Rancangan yang digunakan Rancangan Acak Lengkap dengan 3 perlakuan 3 ulangan. Perlakuan A padat penebaran 7 ekor/L (35 ekor/akuarium), perlakuan B padat penebaran 8 ekor/L (40 ekor/akuarium), dan perlakuan C padat penebaran 9 ekor/L (45 ekor/akuarium). Parameter pertumbuhan panjang mutlak, pertumbuhan bobot mutlak, kelangsungan hidup, konversi pakan dan kualitas air. Data dianalisis menggunakan uji normalitas, uji homogenitas dan analisis sidik ragam (ANOVA). Hasil penelitian pertumbuhan panjang mutlak tertinggi pada padat penebaran 7 ekor/L sebesar 0,61 cm, pertumbuhan bobot mutlak padat penebaran 8 ekor/L sebesar 0,32 g, kelangsungan hidup padat penebaran 7 ekor/L sebesar 30,48%, dan konversi pakan padat penebaran 8 ekor/L sebesar 0,13 g. Kualitas air masih dalam kisaran layak untuk pemeliharaan benih ikan gurami.

Kata kunci: Benih gurami, padat penebaran, pertumbuhan, kelangsungan hidup.

Abstract

Fish farming activities need to be carried out to meet the needs and prevent extinction, especially those of important economic value such as gouramy. The purpose of this study was to analyze the variation in stocking density of gouramy (Osphronemus gouramy Lac.). The research was conducted at the Mentaos Ornamental Fish Center Pokdakan Mina Satuhati Jl. East Mentaos Rt. 01, Rw 03, Mentaos Village, North Banjarbaru District, Banjarbaru City. The design used was a completely randomized design with 3 treatments and 3 replications. Treatment A with a stocking density of 7 fish/L (35 fish/aquarium), treatment B with a stocking density of 8 fish/L (40 fish/aquarium), and treatment C with a stocking density of 9 fish/L (45 fish/L). Parameters of absolute length growth, absolute weight growth, survival, feed conversion and water quality. Data analysis used normality test, homogeneity test and analysis of variance (ANOVA). The results showed that the highest absolute length growth at a stocking density of 7 fish/L was 0.61 cm, the absolute growth at a stocking density of 8 fish/L was 0.32 g, survival at a stocking density of 7 fish/L was 30.48%, and conversion of 8 fish/L stocking solid feed of 0.13 g.The water quality is still within the acceptable range for the maintenance of gouramy seeds.
