Studies on the artificial propagation of hybrid bream in brackish water
Hybrid bream (BBTB) is a high-quality bream derived from a hybrid lineage of blunt snout bream (Megalobrama amblycephala, 2n = 48, BSB, ♀) × topmouth culter (Culter alburnus, 2n = 48, TC, ♂). In this study, to explore the laws of artificial propagation of BBTB in a brackish water environment, 150 pairs of BBTB with an average weight of 1000 g were selected as brood fish, and a successful artificial propagation experiment was carried out at the Freshwater Fish Nansha (Nanfan) Breeding Center (2‰–5‰ brackish water). The fertilization and hatching rate was 86% and 78%, respectively, and a total of 1 800 000 larvae were obtained. After 26 days of cultivation, 400 000 larvae survived, showing a survival rate of 22%. This study is of great significance regarding the basic theories and applications of fish genetics.
