Kinerja Pertumbuhan Ikan Nila (Oreochromis sp.) dengan Penambahan Mineral Tembaga (Cu) pada Pakan

Abstract

Tembaga (Cu) termasuk ke dalam mikromineral yang dibutuhkan dalam jumlah sedikit pada tubuh, akan tetapi berdampak terhadap metabolisme dan kesehatan ikan. Penelitian ini bertujuan untuk mengetahui pertumbuhan ikan nila (Oreochromis sp.) yang ditambahkan mineral tembaga (Cu) pada pakan.Terdapat empat perlakuan berbeda, yaitu Cu 0 (pakan tanpa penambahan mineral Cu), Cu 1 (pakan dengan penambahan mineral Cu 1 mg kg-1), Cu 2 (Pakan dengan penambahan mineral Cu 2 mg kg-1), Cu 3 (Pakan dengan penambahan mineral Cu 3 mg kg-1). Ikan nila berukuran 8,75±0,02 g sebanyak 15 ekor dipelihara dalam akuarium ukuran 60×50×40 cm dengan ketinggian air 30 cm selama 60 hari. Ikan diberi pakan tiga kali sehari secara at satiation. Hasil penelitian menunjukkan bahwa parameter kinerja pertumbuhan ikan nila yang diberi penambahan mineral tembaga (Cu) menunjukkan hasil berbeda nyata (P<0,05) terhadap ikan nila kontrol. Berdasarkan hasil penelitian, dosis terbaik penambahan mineral tembaga (Cu) pada ikan nila yaitu 2 mg kg-1 pakan.

Copper (Cu) is included in the microminerals that are needed in small amounts in the body, but have an impact on the metabolism and health of fish. This study aims to determine the growth of tilapia (Oreochromis sp.) which are added with copper (Cu) minerals in their feed. There are four different treatments, namely Cu 0 (feed without the addition of Cu minerals), Cu 1 (feed with the addition of Cu minerals 1 mg kg-1), Cu 2 (Feed with the addition of Cu minerals 2 mg kg-1), Cu 3 (Feed with the addition of Cu minerals 3 mg kg-1). Tilapia measuring 8,75±0,02 g as many as 15 fish were kept in an aquarium measuring 60×50×40 cm with a water height of 30 cm for 60 days. Fish were fed three times a day at satiation. The results showed that the performance parameters of the growth of tilapia given the addition of copper (Cu) minerals showed significantly different results (P <0,05) compared to the control tilapia. Based on research results, the best dose of copper (Cu) mineral addition to tilapia is 2 mg kg-1 feed.
