Biotechnology applied to fish reproduction: tools for conservation
(2018-04-29)
This review discusses the new biotechnological tools that are arising and promising for conservation and enhancement of fish production, mainly regarding the endangered and the most economically important species. Two main ...
Induced sterility in fish and its potential and challenges for aquaculture and germ cell transplantation technology: A review
(2016-08-01)
Interest in reproductively sterile fish in aquaculture has prompted research into their production. Several methods are available for inducing sterility and optimizing its application in the global fishery industry. ...
Triploid or hybrid tetra: Which is the ideal sterile host for surrogate technology?
(2018-03-01)
This work was aimed at developing an effective procedure to obtain sterile ideal host fish in mass scale with no endogenous germ cells in the germinal epithelium, owning permanent stem-cell niches able to be colonized by ...
Stereological analysis of gonads from diploid and triploid fish yellowtail tetra Astyanax altiparanae (Garutti & Britski) in laboratory conditions
(Cambridge Univ Press, 2017-08-01)
This study aimed to examine the gonadal morphology of diploid and triploid fish through stereological analysis. Triploid individuals were obtained after temperature shock (40 degrees C for 2 min) at 2 min post-fertilization ...
Synaptonemal complex analysis in the fish species Piaractus mesopotamicus and Colossoma macropomum, and in their interspecific hybrid
(2002-01-01)
The surface-spreading technique for visualization of whole cell synaptonemal complex (SC) complements was employed to study the chromosome synapsis in spermatocytes of P. mesopotamicus, C. macropomum and in their interspecific ...
The effects of temperature and busulfan (Myleran) on the yellowtail tetra Astyanax altiparanae (Pisces, Characiformes) spermatogenesis
(Elsevier B. V., 2015-10-01)
We aimed to standardize a protocol to suppress spermatogenesis in the characiform fish, Astyanax altiparanae, for future use as a host in germ cell transplant research, opening opportunities for a range of studies, such ...
Hydrolysis of raw fish proteins extracts by Carnobacterium maltaromaticum strains isolated from Argentinean freshwater fish
(Elsevier Science, 2021-03)
Lactic acid bacteria (LAB) isolated from freshwater fish (hatcheries and captures) from Paraná river (Argentina) were analyzed by using culture-dependent approaches. The species belonging to Carnobacterium (C.) divergens, ...
