Cannibalism mitigation in striped murrel, Channa striata, with hatchery seed weaned on pellet diet: A review

Abstract

Striped snakehead is one of the important food fish of high commercial value due to preference for its meat quality, therapeutic and antinociceptive properties. The species is distributed in many countries in South Asia to South‐East Asia. The current production of the species is largely contributed from the capture fisheries as there are several inherent problems associated with its farming. The major bottlenecks for aquaculture production are insufficient knowledge on reproductive biology, captive breeding, higher mortalities of larvae in nursing phases, intracohort cannibalism and non‐acceptance of artificial diet. The available information on these issues is sparse, often anecdotal and needs comprehensive up‐scaling. To address this gap, this review compiles the available information on this species to have a better understanding of reproductive biology, captive spawning, larval rearing, cannibalism mitigation, nursery rearing of seed in different rearing systems, and most important being weaning seed on the artificial diet so that this species could be cultured on artificial diets in the grow‐out systems. It is expected that this review would provide useful information for the production of feed‐weaned hatchery‐seed.

Hatching success and growth of Snakehead (Channa lucius Cuvier, 1831) larvae and fry at different pH levels

“…All tanks were continuously aerated and changed every three days with 20-30% of the tank volume. The rearing period was 30 days in order to limit changes in feed requirements and the cannibalism of the Snakehead fish in the larger stage in captivity (Raizada et al, 2022), which may affect the results. After every ten rearing days, ten fish from each plastic tank (30 fish of each pH level) were weighed using an electrical analytical balance calibrated to 0.01 mg and measured on a divided ruler of a millimeter unit to calculate their growth performance.…”

Pemanfaatan Ikan Gabus (Channa striata) dalam Pengobatan Osteoarthritis

“…Ikan ini dapat dengan mudah ditemukan di berbagai perairan terbuka di Indonesia, terutama di pulau Jawa, Sumatera, Kalimantan, Sulawesi, Bali, Lombok, Singkep, Flores, Ambon dan Maluku. Klasifikasi ikan gabus adalah sebagai berikut [16]: Kingdom : Animalial Kelas : Actinopterygii Ordo : Perciformes Famili : Channidae Genus : Channa Spesies : Channa striata Ikan gabus berbentuk hampir bulat, panjang dan lebih padat. Bagian belakang ikan cembung, sedangkan perut cukup rata dengan kepala seperti ular.…”

“…Ikan gabus juga memiliki sirip punggung dan duri keras di dalamnya. Ikan ini bisa mencapai panjang 90-110 cm [16]. Kandungan ikan gabus berupa 25,55% protein dengan kadar albumin yang tinggi serta kandungan mineral Zn, asam amino esensial serta non esensial [17].…”

Pemanfaatan Ekstrak Ikan Gabus (Channa striata) untuk Penyembuh Luka pada Pasien Diabetes Mellitus (Ulkus Diabetikum)

“…Bagian belakangnya cembung, bagian perut cukup rata dan kepala seperti ular. Identifikasi dari ikan gabus sebagai berikut [28]: Kingdom : Animalial Kelas : Actinopterygii Ordo : Perciformes Famili : Channidae Genus : Channa Spesies : Channa striata Berdasarkan penelitian yang dilakukan oleh Prasatari dkk (2017), menyebutkan bahwa dari 15 jenis asam amino yang dikandung oleh protein ikan gabus (Channa striata), terdapat 9 jenis asam amino esensial. Senyawa albumin yang dikandung dalam ikan gabus digunakan untuk antioksidan disel β pankreas yang mana ekstrak ikan gabus ini akan meregenerasi jaringan pankreas yang rusak akibat diinduksi aloksan [7], [12], [18].…”
