Última Genetic variation in a closed line of the white shrimp Litopenaeus vannamei (Penaeidae) Genet. Mol. Biol. Luvesuto,Eloize; Freitas,Patrícia Domingues de; Galetti Junior,Pedro Manoel. The culture of the marine shrimp Litopenaeus vannamei has recently boosted the Brazilian shrimp industry. However, it is well known that selection methods based solely on phenotypic characteristics, a reduced number of breeders and the practice of inbreeding may promote a significant raise in the genetic similarity of the captive populations, leading to greater disease susceptibility and impairing both the growth and final size of the shrimps. We used four microsatellite loci to investigate genetic variation in three generations (F5, F6 and F7) of a closed and reared L. vannamei lineage. Although an accentuated heterozygosis deficit was detected, we also observed that the captive propagation of this lineage did not lead to a significant loss of genetic...

Y.; Le Moullac, Gilles; Cuzon, Gerard; Van Wormhoudt, A. Human growth hormone like peptides were present in Penaeus indicus as two molecular forms: one with a molecular weight about 25 kDa which is similar to that of the vertebrate growth hormone and a smaller form of 2 kDa. Quantitative variations of hGH-like peptides in different larval stages of three species of Penaeids (Penaeus vannamei, P. stylirostris, P. indicus) suggest a possible involvement of hGH-like peptides in the development. Human growth hormone (hGH) supplementation in the diet of Penaeus vannamei larvae seems to have a positive effect on the size and on the quality of the animals estimated by their resistance to salinity stress.
