Problems solved by technology

[0004] Technical problem to be solved: The purpose of this study is to explore a method for aquaculture of grouper in inland areas through artificial seawater. The nutrient composition difference of the grouper under the condition of artificial seawater and natural seawater culture, draws the growth performance of the oblique-banded grouper cultivated by this invention is better, and the nutrient composition is higher than that of the grouper cultivated in natural seawater

Abstract

The invention discloses a method for cyclically cultivating Epinephelus coioides with artificial seawater indoors, which comprises the following steps of preparation of artificial seawater, preparation of cultivation water, selection of fry, regulation and control of water quality, selection of feed, daily sewage suction and water change, and cleaness maintenance of the bottom and walls of a pond. The method is efficient and environment-friendly; Epinephelus coioides obtained according to the method can be high in quality and yield, and healthy, in addition the cultivating survival rate is high, and the feed coefficient is low.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to the preparation of artificial seawater, the setting of optimal breeding conditions and the operation flow in the breeding process. Background technique [0002] Slanted grouper (Epinephelus coioides), commonly known as blue spot, belongs to the order Perciformes, the family Acididae, the grouper subfamily, and the genus Grouper. Its adult fish often inhabit sea areas on rocky reefs and sandy mud bottoms, and juvenile fish mostly appear in Near the intertidal zone, it is a warm-water middle and lower layer fish, mainly distributed in the Indian Ocean, the Red Sea, the Mediterranean Sea, the western North Pacific Ocean and Southeast Asia. It is an important cultured species in my country and has high economic value. [0003] At present, grouper farming is mainly concentrated in coastal areas, and natural seawater and climate resources are used for farming. The consumption dema...
