Effect of water temperature on individual reproductive activity of pollack (Pollachius pollachius) ArchiMer
Suquet, Marc; Normant, Yvon; Gaignon, Jean-louis; Quemener, Loic; Fauvel, Christian.
The effects of water temperature on pollack (Pollachius pollachius) spawning features were individually assessed. During the spawning period, nine fish sets, each composed of one female and two males (mean body weight: 2.5+/-1.0 kg), were placed in small-volume tanks (2 m(3)). Fish sets were held at 8, 10, or 12 degreesC (n=3 for each temperature). Three females released eggs at 8 and 10 degreesC, while only two spawned at 12 degreesC. One hundred thirty-one individual spawns were collected from the eight spawning fish sets. The number of spawns collected per female was significantly lower at 12 degreesC (3.0+/-3.6), compared to 10 degreesC (17.3+/-10.1) and 8 degreesC (23.3+/-2.5). Egg number (eggs kg(-1) BW) was significantly lowered at 12 degreesC...

Effects of hypoxia and elevated ammonia concentration on the viability of red snapper embryos and early larvae ArchiMer
Bardon-albaret, Agnes; Saillant, Eric.
The effects of hypoxic conditions and elevated ammonia concentrations on the viability of embryos and newly hatched larvae of the red snapper (Lutjanus campechanus) were investigated. In all experiments, tested levels of hypoxia or ammonia concentrations were applied to embryos and unfed newly hatched larvae from three different spawns. Exposures began at 1 h post fertilization (pf) and lasted until all individuals in a group had expired. Survival rates were monitored daily in duplicates for each spawn in each treatment. Fertilized eggs exposed to 2 mg L− 1 dissolved oxygen (29% saturation) showed complete mortality before hatch while 81% of embryos in control groups (> 85% saturation) hatched and subsequently maintained high survival until 5 days pf....

Egg quality in domesticated and wild seabass (Dicentrarchus labrax): A proteomic analysis ArchiMer
Crespel, Amlie; Rime, Helene; Fraboulet, Erwann; Bobe, Julien; Fauvel, Christian.
In order to improve Our understanding of factors determining egg quality in fish, seabass egg batches obtained from 34 females held under standard conditions, were assessed for biological performances and a fraction from each batch was subjected to proteomic analysis. Comparison of proteomic patterns from eggs of different quality revealed differential protein spots among which one was identified as Nucleoside Diphosphate Kinase, a highly conserved protein involved in cell proliferation. This study shows that molecular markers may help understand factors determining egg quality in fish.

Induced spawning of red drum, Sciaenops ocellatus: use of multivariate and univariate analysis methods in the search for side effects of LH-RHa treatments and ovarian development state upon spawn quality ArchiMer
Gardes, Lionel; Villanove, Philippe; Buchet, Vincent; Fauvel, Christian.
The present work examines the usefulness of the combination of multivariate analyses and further one-way analysis of variance in the search for links between causes and effects in heterologous stimulation of spawning in fish. Stimulations with both 20 and 50 mu g . kg(-1) doses of [D Trp(6)] luteinizing hormone-releasing hormone analogue (LH-RHa) were effective in inducing and synchronizing spawning of red drum, Sciaenops ocellatus. Oocyte development monitoring using ovarian biopsy allowed treatment injections at different stages of maturation. The influence at stimulation time of female oocyte development state upon further development was shown. An interesting potential of second stimulation, leading to high quality spawns, was established and factors...

Maternally Inherited npm2 mRNA Is Crucial for Egg Developmental Competence in Zebrafish ArchiMer
Bouleau, Aurelien; Desvignes, Thomas; Traverso, Juan Martin; Nguyen, Thaovi; Chesnel, Franck; Fauvel, Christian; Bobe, Julien.
The molecular mechanisms underlying and determining egg developmental competence remain poorly understood in vertebrates. Nucleoplasmin (Npm2) is one of the few known maternal effect genes in mammals, but this maternal effect has never been demonstrated in nonmammalian species. A link between developmental competence and the abundance of npm2 maternal mRNA in the egg was previously established using a teleost fish model for egg quality. The importance of maternal npm2 mRNA for egg developmental competence remains unknown in any vertebrate species. In the present study, we aimed to characterize the contribution of npm2 maternal mRNA to early developmental success in zebrafish using a knockdown strategy. We report here the oocyte- specific expression of npm2...

Nutrition, digestion et développement des larves de crevettes et poissons marins ArchiMer
Cahu, Chantal.
This report is presented by Chantal Cahu for obtaining accreditation to supervise research. Since 1981, her research activity has addressed the study of reproducers' nutrition and the young stages of development of marine organisms belonging to two different branch lines, crustaceans and fish. This work, performed in a base-lined research body, IFREMER, is placed within a more general programme of aquaculture development. Indeed, whatever species are at issue, the development of aquaculture in France, as at the global level, is based on the production of juveniles in hatcheries. My work has therefore more precisely the goal of acquiring knowledge about the nutritional needs, mechanisms of digestion and the development of these animals in order to improve...

Santos, Graciene Conceição; Garcia, Edivaldo Antonio; Vieira Filho, Javer Alves; Molino, Andrea Britto; Pelicia, Kleber; Berto, Daniella Aparecida.
Aiming to assess isoleucine levels in low protein diets for laying Japanese quails, 648 quails of 182 days of age were distributed in experimental block design with six treatments and six replicates of 18 birds each. Treatments consisted of a basal level corresponding to 0.672% isoleucine and supplemented with isoleucine to the levels of 0.816, 0.960; 1.104; 1.248%. The experimental diets were compared to a control diet containing 20% CP. The parameters studied were: performance, egg quality, total solids and nitrogen in the excreta. There was a linear increase only for isoleucine intake with increasing levels of isoleucine in the diets. The comparison of mean values of each combination of isoleucine levels for diets with 16% CP with the control with 20%...
