PENAMBAHAN SILASE JEROAN IKAN PATIN TERHADAP PERTUMBUHAN DAN KELANGSUNGAN HIDUP IKAN LELE (Clarias sp.)

Abstract

Meeting the needs of feed today is experiencing a difficult time due to the high price of feed raw materials, especially fish meal, so that the impact on the price of the ration. Depending on the main source of protein in fish meal will certainly cause the availability of fish meal to be increasingly limited. Therefore an alternative source of protein is needed to reduce the use of fish meal in feed. Utilization of fishery waste into feed material can provide important significance for fisheries production, one of which allows it to be used as an alternative feed material is catfish processing waste on catfish viscera. This study aims to determine the effectiveness of catfish viscera in the manufacture of feed ration so as to produce growth and survival of catfish (Clarias sp.). The experimental design used was a Completely Randomized Design with 3 treatments and 3 replications with A treatment (25% fish meal + 75% catfish viscera silage), B (50% fish flour + 50% catfish viscera silage), and C (75% fish meal + 25% catfish viscera silage). The results of the study conducted, showed the highest relative growth velocity value (%) of test fish in treatment C (222.63%) compared to treatments A (120.35%) and B (164.72%), the value of the feed conversion ratio (RKP) in treatment C obtained results which is relatively low with a value of 1.09 compared to other treatments that is 1.74 in treatment and treatment B with a value of 1.38. There was no significant effect on the addition of catfish viscera to the feed on the survival of catfish, so that there were no significant differences between treatments. Water quality in this study still supports the growth of catfish seedlings that are maintained.

THE CULTURE OF CATFISH (Clarias sp.) FRY IN THE PEAT POND BASED ON PINEAPPLE (Ananas comosus L) TUBER AND BANANA (Musa sp.) STEM CRUDE EXTRACT WITH COMMERCIAL PROBIOTIC MIX

“…In general, the bacteria that live in the intestines of fish have a very important role and have the potential to produce various enzymes. These microbiota are capable of producing proteolytic, amylolytic, cellulolytic, lipolytic and chitinolytic enzymes, which play a very important role in digesting protein, carbohydrates, cellulose, fat and chitin (Bairagi et al, 2002;Fisheries Journal, 14(2), 1002-1010. http://doi.org/10.29303/jp.v14i2.884 Djauhari et al (2024) Gutowska et al, 2004. The enzymes produced by these microbiota are very beneficial because they are used as probiotic supplements when formulating fish feed, especially in the larval stage of fish.…”

“…The treatments given in this study were supplementation without crude extract of pineapple tubers and banana stems as well as commercial probiotic mix (treatment A), supplementation with crude extract of pineapple tubers at a dose of 6%, crude extract of banana stems at a dose of 2% and commercial probiotic mix at a dose of 0.2%. (treatment B), supplementation with crude extract of pineapple tuber at a dose of 6%, crude extract of banana stem at a dose of 2% and commercial probiotic mix at a dose of 0.4% (treatment C), supplementation for crude extract of pineapple tuber at a dose of 6%, crude extract of banana stem at a dose of 2 % and a commercial probiotic mix dose of 0.6% (treatment D) (v/v/w/w) (Djauhari et al, 2024) in catfish fry kept in peat ponds.…”

“…Fisheries Journal, 14(2), 1002-1010. http://doi.org/10.29303/jp.v14i2.884 Djauhari et al (2024) Pineapple tubers and banana stems were blended by adding 0.9% NaCl solvent in a ratio of 1:1 (w/v). Next, the mixture is filtered with a cloth mask and squeezed until a crude extract of pineapple tubers and banana stems is obtained.…”

“…Pineapple tubers contain vitamins A, B3, B6, B12, antioxidants, phenols and flavonoids, soluble sugars, fiber and aroma attractants (Sun et al, 2016) which play a role in improving digestive metabolism and absorption of feed nutrients. Several research results in the field of aquaculture that utilize crude pineapple extract as a source of bromelain enzymes include: Wiszniewski et al (2019) using pineapple extract at doses of 10 and 20 g/kg feed can increase Fisheries Journal, 14(2), 1002-1010. http://doi.org/10.29303/jp.v14i2.884 Djauhari et al (2024) growth, feed efficiency and nonspecific immune response of Acipenser ruthenus. Supplementation of pineapple extract at a dose of 0.2 ml/kg feed produces the best feed efficiency values, protein efficiency ratio, and specific growth rate of vaname shrimp (Litopenaeus vannamei) (Rachmawati & Samidjan, 2018).…”

Growth performance and blood figures of African catfish (Clarias sp.) fed with marine fungal fermented feed

“…Catfish production in 2011-2018 showed a fairly good performance with an average production increase of 47% [1]. Factors that are quite important in fish maintenance are the provision of high nutrition and feed to support growth, reproduction, and fish blood conditions [2]. The high increase in production have a positive correlation with the ever-increasing market needs, so it must be accompanied by the provision of good seeds with optimal use of feed.…”
