“…Energy for growth is available only after other demands are met. Stress may occur due to poor water quality (Donaldson, 1981;Schereck, 1981;Pickering, 1992), handling (Mazeaud et al, 1977;Donaldson, 1981;Pickering, 1992) and grouping (Wohlfarth, 1977;Volpato et al, 1989;Fernandes and Volpato, 1993;Barbosa et al, 1996), all of which have been reported as growth suppressors.…”

“…Although this may occur because of growth enhancement in some fish (Wohlfarth, 1977), growth suppression is often observed among individuals within a group (Allen, 1972;Volpato et al, 1989;Karplus et al, 1992;Volpato and Fernandes, 1994). Differences in growth rates have been found in isolated fish, which may be attributed to genetic (including sex) sources.…”

In the present study, the effect of chemical factors released by conspecifics on growth variability (heterogeneous growth -HetG) in a gregarious fish species (Prochilodus lineatus) was tested. HetG was assessed by the weight variation coefficient in two consecutive 21-day periods. The fish were grouped in tanks (4 fish in each) that received running water with constant draining. The tanks contained either conspecifics (C) or non-conspecifics (N). Four conditions were established in accordance with the tank water supply: a) water with previous contact with conspecifics throughout the experiment (CC); b) water without previous contact with conspecifics throughout the experiment (NN); c) water with previous contact with conspecifics in just the first period, 0 to 21 days (CN); and d) just in the period from 21 to 42 days (NC). At the end of the experiments, the occurrence of chemical modulation on the growth variability in P. lineatus was verified: the fish that received water with previous contact with a conspecific (C) presented exacerbation of HetG. This corroborates the notion that the predominant mechanism in the determination of intraspecific growth variation in the gregarious species is associated to chemical factors released by conspecifics.

“…Récemment, il a été montré que la technique du «communal testing» pouvait aussi être appliquée à des structures d'élevage en cage pour la carpe et que les souches les plus performantes en cages flottantes n'étaient pas les plus performantes en bassins (WOHLFARTH et MOAV, 1991, 1993 Selon KIRPICHNIKOV (1987), des différences significatives de potentiels de croissance existent suivant le stade de développement. La race «Ropsha» présenterait ainsi une croissance plus rapide que celle des autres souches, la première année seulement.…”

“…In addition to hybridization in natural ecosystems, usually between native and nonnative taxa, artificially induced hybridization has been employed as a tool to improve aquaculture productivity through heterosis in fish (Moav, 1979;Ihssen et al, 1988;Wohlfarth, 1993).…”

ABSTRACT. An interspecific artificial hybrid was produced between two economically important aquaculture flatfish: olive flounder (Paralichthys olivaceus) and starry flounder (P. stellatus). This hybrid displays the rapid growth characteristic of the former and tolerance to low temperatures and low salinity of the latter, but the genetics of inheritance in this hybrid have not been elucidated. Polymorphic microsatellite markers developed for P. olivaceus and P. stellatus were tested to determine if these markers can be used for analysis of parentage and genetic inheritance. Multiplex PCR using two primer sets that were specific to each species produced PCR products of different sizes; these could be used for the identification of interspecific hybrids. Among the 192 primers derived from olive flounder, 25.5% of the primer sets successfully amplified genomic DNA from starry flounder, and 23% of the 56 primer sets originating from starry flounder amplified DNA from olive flounder. Analysis of genetic inheritance in the hybrid using seven of the 62 microsatellite markers common to both species demonstrated classic Mendelian inheritance of these markers in the hybrid progeny, with the exception of one locus identified as a null allele in the hybrid. These results demonstrate that cross-specific microsatellite markers can be used tools for parentage analysis of hybrid flatfish, for mapping quantitative trait loci, for marker-assisted selective breeding, and for studies of the evolution of fish.
