Cultivo do cavalo marinho Hippocampus reidi (Ginsburg, 1933) em laboratório : reprodução e procedimentos

Abstract

Fish of the species Hippocampus reidi (GINSBURG, 1933) arouse great interest in traditional medicine, aquariums and the renewal of natural stocks. Faced with the threat of extinction, the cultivation projects have awakened a conservationist and sustainable vision in the middle of society. Thus, the objective of the research was to elaborate protocols for the cultivation of Hippocampus reidi (GINSBURG, 1933) for conditions in the laboratory, through tests of reproductive, alimentary and structural management. The H. reidi matrices were captured at four fixed points in the Vaza Barris estuary from January to July 2015. Seven males were collected with the bag in the advanced incubation stage and three couples formed in the same environment. The most effective nursery model was "B1" in terms of survival and handling, with wide lateral flow, better distribution of water outlet and designer more appropriate to the Kreisel effect. The D5 diet, represented by the zooplankton of the natural environment, allowed a survival of 51% after 5 days of life. Proles of matrices captured in the natural environment tend to have a larger number of offspring than the offspring of matings kept in captivity.
