PENAMBAHAN LIMBAH IKAN PATIN (Pangasius sp.) PADA PAKAN TERHADAP KADAR ALBUMIN DAN PERTUMBUHAN IKAN GABUS (Channa striata)

Abstract

Snakehead fish (Channa striata) is one of fish type that has the potential to be
cultivated. The albumin levels in snakehead fish are the main attraction for consumers.
Albumin which usually comes from human blood has a fairly expensive price.
Therefore, an alternative is needed to produce albumin at a lower cost. One of the
efforts that can be done is to increase the growth as well as the albumin content in
snakehead fish through feeding rich in protein content. One source of high protein that
is still not widely used by the community comes from fish waste where it is known
that fish waste contains high protein and has the potential to be a source of fish feed
raw materials. This study aims to determine the best dose of catfish offal flour in feed
to increase albumin levels as well as growth in snakehead fish and help reduce
pollution levels from fish waste. The experimental design carried out was a completely
randomized design (CRD) consisting of 4 treatments and 3 replications consisting of
P1: 0%, P2:10%, P3:20%, and P4:30%. The results showed that P1 was the best result
with albumin levels of 12.73 mg/mL, absolute length growth of 1.17 cm, absolute
weight growth of 1.2 g, and survival of 79.17%. The maintenance water quality
measured during the study was the temperature ranged from 26.5-27.4°C, pH ranged
from 6.7-7.1, and dissolved oxygen ranged from 5.25-5.56 mg/L.
