Pemanfaatan Kubis sebagai Bahan Pakan Buatan untuk Pertumbuhan Benih Ikan Lele Mutiara (Clarias gariepinus)
Abstract
Pearl catfish has the main advantage of fast growth. To maximize this growth, one
of the things that must be considered is the feed given. The use of factory feed for
catfish seeds is common, so it is necessary to use feed raw materials that are
around to be used as raw materials for homemade feed. Vegetable waste such as
cabbage and tofu dregs can be used as fish feed which is processed into pellets.
Cabbage vegetable waste, tofu dregs, bamboo shoots and bran have protein and
carbohydrates that can be used for fish growth. This study consisted of 2 stages,
namely stage 1 analyzing the comparison between factory feed and homemade
feed and stage 2 analyzing the difference in dosage of homemade feed on the
growth and efficiency of pearl catfish (C. gariepinus) seed feed. Data were
analyzed using 2 independent samples (unpaired) t-test and ANOVA test. The
results showed that the provision of factory feed and homemade feed did not have
a significant effect on the growth of length, weight, and feed efficiency of catfish
fry. Catfish seeds can be fed homemade feed with ingredients from fermented
cabbage waste, tofu dregs flour, rebon flour, bran flour, plus vitamins and
minerals. The results of the analysis of variance in the treatment of different feed
doses (4%, 5%, 6%, 7%, and 10% per fish body weight), had a significant effect
on the growth of catfish length and weight, and had no significant effect on feed
efficiency. The higher the dose given for the maintenance period of 30 days of
catfish fry gave a good effect with the best dose of 10% per fish body weight
