Abstract

The recent study were attempting to develop spermatogonial germ cell transplantation as a tool to preserve and propagate male germ-plasm from endangered fish species, as well as to produce surrogate broodstock of commercially valuable fish. Spermatogonia identification and testes dissociation were the first necessary steps to obtain highly amount and viable population of spermatogonia as donor cells for transplantation. Using giant gouramy testes as a model, spermatogonia was histological characterized and two methods of testes dissociations were compared (i.e. medium A contained 0.5% trypsin in PBS and medium B contained 0.5% trypsin and DNase 10 IU/μL in PBS complemented with CaCl2, Hepes and FCS). Optimal incubation times (1, 2, 3, 4 and 5 hours) in dissociation medium were also determined. Freshly isolated testes of immature giant gouramy were minced in dissociation medium and then incubated to get monodisperce cell suspension. Parameters observed were number and viability of spermatogonia (ø > 10 μm). The viability was analyzed using trypan blue exclusion dye. The results showed that the average number of spermatogonia observed in medium B was higher than in medium A (P<0.05), meanwhile the viability of spermatogonia between medium A and B were not significantly different (P>0.05). The viability of spermatogonia decreased by the increasing duration time of dissociation. The viability of spermatogonia started to decrease significantly in 2 hours incubation time in medium A and 4 hours incubation time in medium B (P<0.05). In conclusion, application of dissociation medium B yielded higher number of viable spermatogonia than dissociation medium A.

Abstract

One of the obstacles in Asian redtail catfish hatchery is the high cannibalism incidence. Cannibalism is associated with aggressive behavior caused by hormonal metabolism especially of testosterone. The purpose of this study was to evaluate the effect of testosterone administration on the cannibalism incidence in the Asian redtail catfish juveniles.  The experiment was conducted by rearing fish with initial length of 4.09±0.19 cm in 16 of 20 L aquariums with a density of 2 fish L-1. The experiment was designed with a completely randomized design with 4 treatments which were different level of 17α-methyltestosterone supplementation in feed, i.e., 0 mg kg-1 feed (A) as control, 7.5 mg kg-1 feed (B), 15 mg kg-1 feed (C), and 30 mg kg-1 feed (D). Each treatment has 4 replications. Fish fed experimental diet (40% protein) 4 times a day to satiation for 30 days. The parameters observed were type and index of cannibalism, aggressive behavior, survival rate, normal mortality, growth performance, hormones concentrations (estradiol, testosterone, and cortisol), and water quality. The results showed that cannibalism type II (the fish eaten completely or missing) and cannibalism index increased with the increasing doses of testosterone administration in the feed with the highest cannibalism incidence was 40.63%. The highest survival rate was found in treatment B (73.75±2.50%) and was not significantly different from the control treatment (69.38±2.39%). No differences in testosterone concentration and in the growth performance among the treatments.  However, there was a trend of decrease in the estradiol concentration of Asian redtail catfish juveniles fed ration supplemented with the increasing doses of 17α-methyltestosterone. Based on the results obtained in this research, estradiol changed in the body's plasma, it appears that there was a role for plasma estradiol concentration in controlling cannibalism of Asian redtail catfish juveniles. It concluded that the testosterone administration affected the cannibalism incidence in the Asian redtail Catfish.
