tailieunhanh - Study of biological characteristics and seed production techniques of channa lucius Cuvier 1831

Goal It is to provide scientific arguments about the biological characteristics, and reproductive and rearing techniques of Channa lucius. The success of the project will contribute greatly to the development process of Channa lucius hatchery to supply artificial fish for aquaculture systems and renewable fish resources in the wild in the Mekong Delta as well as in the whole country. | MINISTRY OF EDUCATION AND TRAINING CAN THO UNIVERSITY ABSTRACT OF DOCTORAL DISSERTATION AQUACULTURE AND FISHERIES CODE 62 62. 03. 01 TIEN HAI LY STUDY OF BIOLOGICAL CHARACTERISTICS AND SEED PRODUCTION TECHNIQUES OF CHANNA LUCIUS CUVIER 1831 SCIENTIFIC SUPERVISORS 1.

Introduction Channa lucius Cuvier 1831 which belongs to snakehead is found in freshwaters like rivers lakes canals rice fields and forests of nature conservation in the Mekong River Delta MRD . Channa lucius meat that is tasty and appetizing people has respiratory organs with natural air so it is easy to feed and the fish can live well in water from to low pH Rainboth 1996 Lee and Ng 1994 . Many people feeding fish in the MRD think that the fish has very promising development of commercial products especially cultured in ponds pens and cages. Currently the main sources of Channa lucius fries are exploited naturally in small quantities and with insustainable quality. Meanwhile the studies of this species is not much and the information is only limited in the initial basic research on biological characteristics and natural reproductive techniques. Therefore the study of growing Channa lucius into a new cultured species which will have a great effect in the diversification of cultured species thus contributing to reducing risks in farming and food supply needs for society is a matter of urgency. As a result the topic Study of biological characteristics and seed production techniques of
