Peningkatan Kinerja Reproduksi Induk Ikan Patin Pangasianodon hypophthalmus yang diberi Pakan Tambahan Cacing Tanah Segar Lumbricus rubellus

Abstract

Budidaya Pematangan gonad induk masih menjadi hambatan utama dalam budidaya ikan patin Pangasianodon hypophthalmus. Penelitian ini bertujuan mengevaluasi pengaruh suplementasi cacing tanah segar dalam pakan terhadap performa reproduksi induk ikan patin menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 3 ulangan, pengujian meliputi kontrol (pakan komersial 1%), serta penambahan cacing tanah segar 1% (CS1) dan 2% (CS2). Hasil penelitian menunjukkan perlakuan CS2 memberikan hasil optimal, dengan capaian Indeks Kematangan Gonad (IKG) 18,93%, fekunditas 193.548–260.869 butir/kg, Fertilization Rate (FR) 85%–89%, Hatching Rate (HR) 80%–85%, dan diameter telur 1,45 mm. Analisis proksimat mengonfirmasi bahwa cacing tanah segar memiliki kandungan protein dan lemak yang lebih tinggi daripada pakan komersial. Disimpulkan bahwa penambahan cacing tanah segar 2% efektif meningkatkan kualitas reproduksi induk ikan patin.

Gonad maturation of broodstock remains a major obstacle in the cultivation of striped catfish Pangasianodon hypophthalmus. This study aimed to evaluate the effect of fresh earthworm supplementation in feed on the reproductive performance of striped catfish broodstock. Using a Completely Randomized Design (CRD) with 3 treatments and 3 replications, the test included a control (1% commercial feed), and the addition of fresh earthworms at 1% (CS1) and 2% (CS2). The results showed that the CS2 treatment provided optimal results, achieving a Gonadosomatic Index (GSI) of 18.93%, fecundity of 193,548–260,869 eggs/kg, Fertilization Rate (FR) of 85%–89%, Hatching Rate (HR) of 80%–85%, and egg diameter of 1.45 mm. Proximate analysis confirmed that fresh earthworms have higher protein and fat content than commercial feed. In conclusion, the addition of 2% fresh earthworms is effective in improving the reproductive quality of striped catfish broodstock.
