“…In sharp contrast, inbreeding did not depress mean juvenile growth rates for other marine invertebrates that have been studied, such as the scallop Argopecten purpuratus (Winkler & Estévez 2003), the Pacific oyster Crassostrea gigas (Hedgecock et al 1995), the Japanese pearl oyster Pinctada fucata martensii (Wada & Komaru 1994), and C. fornicata (the present study). In compiling results from 40 outbreeding plant species, Husband & Schemske (1996) found that on average self-fertilization decreased plant growth and reproduction (flower number, seed number/flower, etc.)…”

“…For example, in the Japanese pearl oyster Pinctada fucata martensii, survival of inbred juveniles was only 5% less than that of outbred juveniles (Wada & Komaru 1994), and in the ascidian Corella willmeriana, inbreeding had no effect on juvenile survival at all (Cohen 1996). In 40 captive mammalian populations belonging to 38 species, offspring from sibling matings had on average 33% lower survival than those from unrelated parents (Ralls et al 1988), which is still lower than the average decrease we found for Crepidula convexa (41.8%).…”

“…Estimation of inbreeding levels is particularly relevant in closed cultivated populations since they are usually small and since inbreeding may alter the response to artificial selection pressure and endanger the future of a selection programme. Moreover, inbreeding depression seems to be important in some bivalves (Beattie et al, 1987 ;Wada & Komaru, 1994 ;Ibarra et al, 1995 ;McGoldrick & Hedgecock, 1997), among them Ostrea edulis (Bierne et al, 1998).…”

SummaryGenetic variability for growth was analysed in three populations of Ostrea edulis, selected for resistance to the protozoan parasite Bonamia ostreae. This study was undertaken first to determine the potential for selection for growth in populations that have never been selected for this character, and second to estimate heterosis versus inbreeding depression. Growth was monitored in culture for 10 months. The selected populations (namely S85-G3, S89I-G2 and S89W-G2), their crossbred population and a control population were composed of full-sib families whose parents were already genotyped using five microsatellite markers. This genotyping allowed the estimation of genetic relatedness among pairs of parents. The parents' relatedness was then correlated with the growth performance of their offspring within each of the three populations, and inbreeding depression was estimated. The population effect for growth was highly significant, with the crossbred population having the highest growth rate, followed by S89I-G2 and S89W-G2, S85-G3 and the control population. The within-populations family effect was also highly significant, indicating, as well as the high value for heritability at the family level (between 0n57 and 0n92), that a potential for a further selection for growth still exists within the three populations. Estimates of inbreeding depression (relative to the mean, for complete inbreeding) were high (1 for S891-G2, 0n44 for S89W-G2 and between 0n02 and 0n43 for S85-G3), which correlates with the apparent heterosis for growth observed in the crossbred population. These results are discussed in the context of the future management of the selected populations.

Inbreeding depression may be an avoidable phenomenon for abalone culture. However, only a few studies were carried out on inbreeding depression. In the present study, to demonstrate inbreeding depression in growth trait of Pacific abalone, H. discus hannai, inbreeding and outbreeding families were produced in 2010. Inbred and outbred families from each experiment were reared in same tank until 10 month for the same breed environment. The individual of inbred and outbred were distinguished by paternity test using microsatellite DNA. The shell length between inbred and outbred families was compared. At the results, significantly higher shell length was observed in the outbred families at 10 mon (P < 0.05). These results indicate that inbreeding depression is obviously observed in growth traits in the first generation of full-sib family of the H. discus hannai.
