A Study on the Metabolic Rate Change Pattern in F2 Hybrid Sturgeon, the Bester (Huso huso × Acipenser ruthenus), during the Early Developmental Stage

The primary goal in aquaculture is to maximize the growth and survival of farmed fishes at a minimal cost, which requires an understanding changes metabolism undergone by different fish breeds during development. In particular, highly intensive production systems, such as recirculating require better oxygen consumption. Ontogenetic phase shifts (i.e., sudden changes) have been observed several species early development, metabolic may help predict consumption stages their Here, I analyzed pattern F2 hybrid sturgeon, bester (Huso huso × Acipenser ruthenus; hereafter, referred bester), its ontogenetic body mass values about 0.2 0.8 g. Thus, undergoes can characterize specific developmental period. Therefore, be appropriately adjusted replenished breeding.
