Breeding and Aquaculture of Acrossocheilius hemispinus

The broodstock rearing, artificial breeding and growth characteristics of wild-caught Acrossocheilius hemispinus from waters in Nanping and Longyan areas in the province were studied. During the experimentation, the fish grew and developed normally from fertilized eggs to reach sexual maturity either in ponds or in cement pools with artificial feeding. Although, the in-ground pond aquaculture seemed superior to its counterpart. In 2015-2016, fertilized eggs of the fish were obtained by artificially induced spawning, extrusion and insemination with the average spawning, fertilization, and hatching rates of 78.9%, 74.8%, and 73.7%, respectively. Running water, oxygenation, or a combination of running water and oxygenation was conducive to successful egg hatching. The average length of a larva was approximately 3 cm after 39 to 51 d of cultivation. The larval survival rate was 70.9%. The growth curves of the larvae, juvenile, and young A. hemispinus were related to the full-length (Y_L), day age (X), and weight (Y_H) of the fish in the exponential functions of Y_L=1.4605e^0.0271x (R²=0.9982), Y_H=0.0217e^0.0967x (R²=0.9876), and Y_L=0.0059Y_H^3.4886 (R²=0.9868), respectively.
