Biologia reproductiva de la saraquita Ramnogaster arcuata (Jenyns, 1842) del estuario del Rio de la Plata. OceanDocs
Rodrigues, K.A..
The reproductive biology of Ramnogaster arcuata inhabiting waters of the Rio de la Plata estuary (Argentina - Uruguay) was studied by using macroscopic and histological analysis of ovaries. R. Arcuata specimens were collected from two research cruises of the National Institute of Fisheries Research and Development (INIDEP) carried out in June 1998 and June 1999. During these surveys, bottom salinity and temperature data were also registered. In addition, information about annual catches of this species in the Rio de la Plata, obtained from different INIDEP cruises performed during the last ten years, was analyzed. During winter, a prevalence of R. arcuata individuals was observed in the Rio de la Plata estuary. In summer, this species apparently moves...

Biologie de l'anchois (<Engraulis encrasicolus>) en Mauritanie OceanDocs
Ba, I.S..
L’étude du cycle sexuel de l’Anchois montre que la principale période de reproduction s’étend d’avril à octobre. Celle-ci serait sous la dépendance principale de l’élévation de la température de surface. La croissance, abordée à l’aide des marques supposées journalières sur les otolithes, donne des résultats jugés satisfaisants jusqu’à 10 cm L.F. Par contre, ceux concernant les tailles supérieures devront être confirmés.

Competition between the sibling species <i>Tisbe holothuriae</i> and <i>T. battagliai</i> (Harpacticoida) OMA
Bergmans, M.; Janssens, P.P.M..
The influence of the salinity on the performance of the sibling species <i>Tisbe holothuriae</i> and <i>T. battagliai</i> in pure and mixed cultures was studied, using laboratory stocks adapted to 32 pro mille for over 175 generations. Cohort studies show that <i>T. holothuriae</i> has higher growth rates (R<sub>0</sub> and r) at 32 pro mille, <i>T. battagliai</i> at 20 pro mille. The latter's life cycle is much less affected by the difference in salinity. 'De Wit' replacement series were used to study competitive interactions. Without water renewal, <i>T. holothuriae</i> eliminates its sibling species in less than 2 generations, apparently through chemical interference. With water...

Contribution a l'etude de la biologie du crabe-tourteau Cancer pagurus sur les cotes de Bretagne sud. ArchiMer
Le Foll, Anne.
The study of the crab Cancer pagurus , along the Brittany coast, has revealed new information about its movements, growth and reproduction. The 1439 crab tagging has been effected either on land using the Edwards technique "suture-tag" or onboard using a similar technique to the Gundersen method of "toggle-tag". The results confirm that males are relatively sedentary, the females migrate more. To estimate growth, the author used the "capture-recapture" method and the results from crab rearing. It appeared that the molt increment is not constant and generally, so the molt frequency, it percentage decreases when the size increases.

Cycle ovarien du merlu, Merluccius merluccius , poisson a ponte fractionnee. ArchiMer
Sarano, F.
The present work analyses and describes Merluccius merluccius ovarian cycle in the Bay of Biscay as an example of partial spawner. Three methods were employed: a macroscopic examination of about 10,000 ovaries -- a cytologic and histologic study -- an investigation of the size structure of the oocytes population of 63 ovaries. The author developed an original mathematical method for serial spawning demonstration. He demonstrates that hake is a partial spawner: a female usually rapidly spawns 4 or 5 times without ovaries rest. On this basis, he gives a new reference scale of the maturity stages of the ovarian cycle: after developing (II), ripe (III), running (IV), the partly spent ovary is named (II+); the repetitive sequence III-IV-II + characterize serial...

Diagnostic des pêcheries du poulpe (octopus vulgaris) dans les eaux sous juridiction sénégalaise. Rapport définitif OceanDocs
Les seiches, poulpes, calmars et nautiles forment la Classe des Céphalopodes de l’Embranchement des Mollusques de grande taille, exclusivement marins. Leur croissance est rapide, leur arrivée à la maturité sexuelle précoce et leur durée de vie courte. Le poulpe a une très large aire de distribution incluant les eaux maritimes tropicales. Elle abonde surtout en Méditerranée, dans les eaux japonaises (Océan Pacifique) et dans l’Atlantique Centre-Est qui s’étend du Maroc à l’Angola. La pêche du poulpe s’est développée au large du Sahara dans les années 1960. Son importance dans la zone du COPACE notamment, au Maroc, en Mauritanie et au Sénégal, s’expliquerait par la raréfaction de ses prédateurs potentiels (Serranidés, Sparidés). Au Sénégal, elle est...

Efeito da somatotropina na hipertrofia das fibras musculares esqueleticas e precocidade reprodutiva de novilhas nelore. Repositório Alice
MOREIRA, P.S.A.; SILVEIRA, A.C.; ARRIGONI, M. de B.; COSTA, C.; CHARDULO, L.A.L.; FURLAN, L.R.; DAL PAI, V..
O trabalho objetivou avaliar o desempenho produtivo, precocidade sexual e hipertrofia das fibras musculares esqueléticas em resposta à aplicação de somatotropina bovina recombinante (rbST). Foram utilizadas 58 novilhas Nelore de sete meses de idade com peso vivo médio de 193 kg. O delineamento experimental foi inteiramente casualizado, em um esquema fatorial incompleto e dividido em duas fases experimentais. Na primeira fase, com duração de 150 dias, os animais foram divididos em dois grupos, de acordo com os níveis de rbST, 0 mg (controle) e 500 mg, a cada 28 dias. Na Fase II, os animais do grupo controle da Fase I foram divididos em 15 e 14 novilhas, que receberam 0 mg e 500 mg de rbST, respectivamente; os animais tratados com 500 mg na Fase I foram...

Evolution and development: some insights from evolutionary theory Anais da ABC (AABC)
DAVID,JEAN R..
Developmental biology and evolutionary biology are both mature integrative disciplines which started in the 19th century and then followed parallel and independent scientific pathways. Recently, a genetical component has stepped into both disciplines (developmental genetics and evolutionary genetics) pointing out the need for future convergent maturation. Indeed, the Evo-Devo approach is becoming popular among developmental biologists, based on the facts that distant groups share a common ancestry, that precise phylogenies can be worked out and that homologous genes often play similar roles during the development of very different organisms. In this essay, I try to show that the real future of Evo-Devo thinking is still broader. The evolutionary theory is...

Fécondité de Nephrops norvegicus dans le golfe de Gascogne ArchiMer
Morizur, Yvon; Conan, Gérard; Guenole, A.; Omnes, Marie-helene.
Females of the Norway lobster Nephrops norvegicus (L.) incubate their eggs under the abdomen for a period of several months. The authors estimated the individual fecundity of N. norvegicus (1) before spawning, and (2) at the end of the incubation period. From these two relationships, they then calculated the average egg loss. Egg loss seems to be relatively higher for small females than for large ones. The mean egg loss estimated for the Bay of Biscay (45%) differs from the only other existing value (75%) calculated by other authors for Portuguese waters. Egg loss may regulate stock-density, and may be a mechanism intervening in stock-recruitment.
