Abstract

The increasing demand for catfish (Clarias sp.) consumption necessitates a sustainable supply of broodstock and seed for aquaculture. One of the main constraints in meeting this demand is the low gonadal maturation rate of catfish outside the natural spawning season. Reproductive hormones play a central role in regulating gonadal maturation through the action of estrogen hormones, particularly 17β-estradiol, which stimulates vitellogenesis or the synthesis of vitellogenin (egg yolk), a major component of oocytes. The increase in vitellogenesis and oocyte size is positively correlated with the level of gonadal maturity. Soybean is a natural source of phytoestrogens that function similarly to estrogen and is rich in linoleic acid, which can stimulate the production of 17β-estradiol. This study aimed to determine the effect of soybean flour supplementation in feed on the Gonadal Maturity Level (GML), spawning success, Gonadosomatic Index (GSI), and Hepatosomatic Index (HSI) of female catfish broodstock. The experimental treatments included a control group (without soybean flour), TK 5% (supplementation of 5% soybean flour per kg of feed), and TK 10% (supplementation of 10% soybean flour per kg of feed). The results showed no significant differences among treatments in terms of GML, spawning success, GSI, or HSI of female broodstock. However, a potential increase in GSI was observed with higher soybean flour supplementation, with the highest GSI value recorded at the 10% dosage level.

Abstract

Feed is one of the key factors in fish culture, including the use of plant-based ingredients such as soybean meal as an alternative protein source that may affect the physiological condition of organs, particularly the liver. This study aimed to analyse the effect of soybean meal supplementation in feed on the liver histological response of catfish (Clarias sp.). Liver histological characteristics were evaluated in three treatment groups: a control group (without soybean meal supplementation),  5% soybean meal-supplemented diet, and 10% soybean meal-supplemented diet. The results showed that the control group exhibited a relatively normal liver histological structure, characterised by an orderly arrangement of hepatocytes, centrally located nuclei, and clearly visible sinusoids. In the 5% soybean meal treatment, more pronounced histological alterations were observed, particularly cytoplasmic vacuolization of hepatocytes, indicating moderate to severe steatosis. Meanwhile, hepatocyte vacuolization was also observed in the 10% soybean meal treatment, but with a severity ranging from mild to moderate compared with the 5% treatment. These findings indicate that dietary soybean meal supplementation affects liver histology in catfish through a non-linear response pattern. The 5% dose caused greater tissue alterations than the 10% dose, which may be associated with the adaptive response of hepatocytes to feed exposure. These findings indicate that the use of soybean meal in fish feed should consider an appropriate dosage to maintain liver health.

Abstract

Program pengabdian kepada masyarakat ini dilaksanakan di Desa Blaru, Kecamatan Badas, Kabupaten Kediri, dengan tujuan meningkatkan kapasitas pembudidaya ikan melalui pelatihan aplikasi probiotik rabal pada pakan dan pengelolaan kualitas air. Metode kegiatan meliputi penyampaian materi, praktik lapangan, serta evaluasi pengetahuan peserta melalui kuisioner pra dan pasca pelatihan. Hasil analisis menunjukkan adanya peningkatan signifikan pada aspek pengetahuan. Pemahaman peserta mengenai pengaplikasian probiotik rabal pada pakan meningkat dari 61,11% menjadi 100%, sedangkan pada pengelolaan kualitas air meningkat dari 5,56% menjadi 100%. Profil peserta didominasi oleh laki-laki usia produktif dengan latar pendidikan menengah serta pengalaman budidaya lebih dari tiga tahun. Kegiatan pengabdian kepada masyarakat berbasis praktik lapangan ini efektif dalam mentransfer pengetahuan dan teknologi tepat guna kepada masyarakat.
