Optimalisasi Suhu terhadap Kinerja Penetasan Telur dan Kelangsungan Hidup Larva Ikan Koridoras Adolfoi Corydoras adolfoi

Abstract

Budidaya ikan koridoras adolfoi saat ini sudah banyak dibudidayakan oleh masyarakat umum, namun informasi dan teknik budidayanya masih belum banyak diketahui sehingga hasilnya belum optimal. Proses inkubasi telur ikan koridoras adolfoi saat ini masih sering terdapat kendala di pembudidaya terutama dalam proses inkubasi telur yaitu waktu penetasannya berjalan lambat, derajat penetasannya rendah, dan kelangsungan hidup larvanya rendah. Tujuan dari penelitian ini adalah bertujuan untuk mendapatkan suhu optimum terhadap kinerja penetasan telur dan kelangsungan hidup larva ikan koridoras adolfoi. Percobaan ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan perbedaan suhu, kontrol (24–26 °C), P1 (27–28 °C), P2 (29–30 °C), dan P3 (31–32 °C) dengan 3 ulangan. Waktu penetasan tercepat diperoleh pada perlakuan P2 (58±1,00 jam), lama waktu penyerapan kuning telur tercepat diperolah pada perlakuan P2 (44,67±1,53 jam), daya tetas telur tertinggi diperoleh pada perlakuan kontrol yaitu 84,67±5,03%, dan kelangsungan hidup larva didapatkan hasil tidak berbeda nyata yaitu (100±00). Kesimpulan, suhu optimum pada parameter derajat penetasan, waktu penetasan, lama waktu penyerapan kuning telur, dan kelangsungan hidup larva yang mampu medapatkan hasil terbaik pada suhu 24–26 °C.

Corydoras adolfoi fish cultivation is currently widely cultivated by the general public, however information and cultivation techniques are still not widely known so the results are not yet optimal. The process of incubating the eggs of the Corydoras Adolfoi fish currently still often has problems for farmers, especially in the egg incubation process, namely the hatching time is slow, the hatching rate is low, and the survival of the larvae is low. The aim of this research is to obtain the optimum temperature for egg hatching performance and survival of adolfoi corydoras fish larvae. This experiment used a Completely Randomized Design (CRD) with 4 different temperature treatments, control (24–26 °C), P1(27–28 °C), P2 (29–30 °C), and P3 (31–32 °C) with 3 repetitions. The fastest hatching time was obtained in the P2 treatment (58 ± 1.00 hours), the fastest egg yolk absorption time was obtained in the P2 treatment (44.67 ± 1.53 hours), the highest egg hatchability was obtained in the control treatment, namely 84.67 ± 5.03%, and the results obtained for larval survival were not significantly different, namely (100 ± 00). In conclusion, the optimum temperature parameters for degree of hatching, hatching time, length of time for egg yolk absorption, and larval survival are capable of getting the best results at a temperature of 24–26 °C.
