1997). Injections or implants of gonadotropin-releasing hormone (GnRH) induce ovulation but not natural spawning. However, successful fertilization of eggs can be attained artificially. A second problem related to captive white grouper propagation is that all young fish are females. Adult females eventually spontaneously invert to males when they get older, but because most fish used/caught are younger females there is often a lack of males for establishing grouper broodstocks. Females can be induced to show sex inversion by injections of 17-α-methyltestosterone, but males produced in this fashion will often revert back to females following hormone removal.
Inbreeding reduced genetic variability, reproduction, longevity and juvenile weight and increased the incidence of blindness. Mäki et al. (2001) describe the positive association between degree of inbreeding and the incidence of elbow and hip dysplasia in Labrador retrievers (C. familiaris), a growth disorder of the bone which causes arthritis. Hedrick and Kalinowski (2000) note that evidence of inbreeding depression in captive or laboratory environments may typically be less than, or at least be different from, the detrimental effects of inbreeding depression in more harsh natural environments.
Controlled inbreeding). Templeton and Read (1984) used this hypothesis to explain the increased viability noted in a relatively small captive population of Speke’s gazelle (Gazella spekei) during its first few generations in captivity. , 2000). Bryant et al. (1999) found with the house fly (M. domestica) that selecting the two top-performing pairs of ten full-sib matings as founders did little to improve fitness over random selection of (two) pairs. At present, experimental support for reducing inbreeding depression through controlled inbreeding is weak (Lacy and Ballou, 1998).
