Abstract

The high demand for catfish motivates farmers to increase production by stocking at a high density. The stress response caused by stocking density, which has an effect on fish growth and survival, is one of the challenges associated with catfish farming with high stocking levels. This issue can be resolved by supplementing catfish feed with vitamin E to stimulate growth. This study aims to determine the effect of vitamin E supplementation on catfish growth, feed efficiency, and survival. This study employs the RAL method with five treatments, including feeding catfish seeds with vitamin E levels of 0 mg/kg feed (P1), 50 mg/kg feed (P2), 100 mg/kg feed (P3), 150 mg/kg feed (P4), and 200 mg/kg feed (P5), with each treatment repeated four times. Adding 100 mg of vitamin E per kg of feed resulted in the highest growth rates (1.66 0.05%/day), a feed conversion ratio of 1.2 0.07, and a feed efficiency of 83.46 3.24% when compared to other treatments and was significantly different (p 0.05). The addition of 100 mg of vitamin E to the feed had no discernible effect on survival compared to other treatments. Keyword: Vitamin E, supplementation, growth, Clarias sp.

Abstract

Artemia salina is a natural food that is very important in hatcheries. The need for Artemia as a natural feed for fish or shrimp seeds is high in Indonesia, so it is necessary to develop local Artemia cultivation. One way to do this is to increase the production of Artemia salina cysts by paying attention to the quality and quantity of feed, namely enrichment with ISP (Isolated Soya Protein) flour in the feed given. ISP is a protein isolated from soybeans with the final product in the form of flour, easy to digest and has high nutritional value. Enrichment with ISP flour was carried out with the aim of increasing the protein content that affects the formation of the shell and the size of the good Artemia salina cyst. This study aimed to determine the effect of different protein concentrations using ISP (Isolated Soya Protein) in bran suspension on the diameter of Artemia salina cysts. The research method used was experimental with a completely randomized design (CRD) using 5 treatments and 4 replications. The results showed that different protein concentrations by enriching ISP flour (Isolated Soya Protein) in bran suspension as feed had a significant effect (P<0.05) on Artemia salina cyst diameter in the third week. The administration of ISP with a protein concentration of 40% and 45% showed the highest Artemia salina cyst diameter.
