Abstract

Pangasius is a freshwater fish included in the main commodity by the Ministry of Marine Affairs and Fisheries, Indonesia. Siamese catfish production ranked 4th in freshwater fish commodities in 2016 after goldfish, tilapia, and catfish. Pangasius has a lack of EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) if compared with fish from the sea. Application of additional different levels of soybean oil in commercial fish fed to enhance EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) in Perkasa pangasiid flesh. This study was conducted to determine the effect of adding soybean oil with different levels of commercial fish feed given to Perkasa striped catfish on growth performance, feed efficiency, EPA (Eicosapentaenoic acid), and DHA (Docosahexaenoic acid). This experimental study used a Complete Randomized Design (CDR) with triplicates and five treatments with additional levels of soybean oil in commercial fish fed: (a) 0%, (b) 2%, (c) 4%, (d) 6%, and (e) 8%. The result showed that treatment of (e) is the best treatment for increasing the EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) in Pangasius flesh. However, additional different levels of soybean oil in the commercial fish feed have no negative effect on growth performance and feed efficiency in Perkasa pangasiid.

Abstract

Carrageenan is a polysaccharide extracted from the seaweed, Kappaphycus alvarezii. Carrageenan serves as a food additive, functioning as both a stabilizer and a gelling agent in vanamei shrimp otak-otak (a type of Indonesian fish cake). This study aimed to determine the effect of different carrageenan concentrations on the sensory acceptance and chemical characteristics of the vannamei shrimp otak-otak. The study was conducted using an experimental method with five treatments: carrageenan addition of 0% (A), 0,5% (B), 1% (C), 1,5% (D), and 2% (E). Preference was assessed using a hedonic test covering appearance, aroma, texture, and taste, as well as a chemical test measuring moisture, ash, fat, protein, carbohydrate, and crude fiber content. Based on the analysis of 20 semi-trained panelists, the most preferred treatment was the addition of 1% carrageenan, with average scores of 7.4 (liked) for appearance, 7.1 (liked) for aroma, 7.5 (liked) for texture, and 7.3 (liked) for taste. Chemical analysis showed 54.66% moisture, 2.34% ash, 8.08% protein, 0.01% fat, 34.91% carbohydrate, and 2.72% crude fiber. The addition of 1% carrageenan was identified as the most favorable concentration compared with the other treatments.

Abstract

The grouper (Epinephelus sp.) is a marine fish species that is widely cultivated commercially for hatchery and grow–out purposes and shows a promising production prospect. The structure and development of fish intestines are influenced by internal and external factors, such as water quality, feed quality, and feed quantity. However, even though the protein content in the diet is relatively high, the growth performance of Epinephelus lanceolatus × Epinephelus fuscoguttatus remains low. This study aimed to determine the effect of papaya simplicia supplementation on grouper growth, specifically absolute weight gain and protein efficiency ratio. The experiment used a Completely Randomized Design with five treatments and three replications (A: papaya simplicia 5%, B: 3.75%, C: 2.5%, D: 1.25%, and E: 0% as the control). Groupers were reared in floating net cages in Pangandaran Regency, Indonesia. Supplementation of papaya simplicia at 3.75% and 5% increased the number of necrotic cells (169 and 183 cells, respectively), as well as the number of goblet cells. The addition of papaya simplicia at 5%, 3.75%, and 2.5% increased the absolute weight gain to 161.36 g, 152.19 g, and 152.09 g, respectively. Supplementation at 5% and 3.75% also increased the protein efficiency ratio to 3.18% and 3.19%, respectively.
