In marine bivalve mollusks, unsaturated molecules called carotenoids are present in the natural diet and play an important role different biological process, especially reproduction. order to gain more insights into these compounds Nodipecten nodosus it was necessary develop a suitable protocol for extraction of from gonads. Female gonads cultured scallops (75 mm length) were lyophilized macerated liquid N2. To verify effect composition organosolvents on extracting solutions, two organic...
In the face of an increasing world population and a subsequent need for increase in sustainable healthy food production, low trophic species, such as oysters, emerge promising alternative. However, regional variations oyster production techniques, market dynamics, consumption patterns create challenges both global local industry’s growth. this study, descriptive qualitative analysis markets across seven Atlantic regions was carried out. The Pacific (Crassostrea gigas) found to be farmed most...
Understanding the effects of environmental parameters on reproductive cycle shellfish is an essential tool for successful hatchery conditioning management and, consequently, seed supply to industry. For tropical oyster, Crassostrea tulipa, little known about factors affecting maturation process and reproduction, but there are indications that salinity may be importance. Two experiments were carried out evaluate broodstock C. tulipa. In first experiment, oysters reared in five salinities (40,...
This work describes the gametogenic cycle of scallop Nodipecten nodosus kept in a culture system. To this end, during one year, samples were taken from broodstocks every 30 days to be submitted macroscopic and microscopic analyses measure amount astaxanthin. perform evaluation, 5 μ slices median portion female part gonad pattern methodology for histological with paraffin HE coloration. The remaining was lyophilised extract quantify levels astaxanthin using HPLC. revealed four well defined...
In this study, broodstock animals of the tropical scallop Nodipecten nodosus were submitted to maturation trials using two dietary sources astaxanthin: dried microalgae Haematococcus pluvialis (Algamac AST) and live obtained from in vitro cultures. The influence astaxanthin on was assessed by analyzing stages gonadal development, accumulation sexual organs, animal fecundity, recovery success rates larvae spat. Two experiments (1 2) performed test concentrations H. mixed with (Isochrysis sp.,...
The tropical clam Anomalocardia brasiliana is a commercially important bivalve living along the south Atlantic coast of Latin America. Harvest natural stocks principal method for supplying market demand—the average price ranging from 5 to 10 US$ per kilogram meat. As first step in development hatchery techniques A. seed production, this study examined effects temperature and salinity on conditioning broodstock spawning. Two treatments tested at 25°C salinities either 30 or 35. A third...
This study evaluated the effects of larval densities, cultured in flow-through system, yield and quantity larvae. The first experiment compared a flowthrough system (80 larvae mL-1) batch (8 mL-1), which resulted higher number after 23 days. second two densities (20 45 system. affected 15 days final all tested times (8, 15, days). After larviculture, was highest for 20 mL-1 mL-1. third also (100 150 did not affect In general, has reduced at densities. Therefore, considering suitable...
This study evaluated the effect of initial larval stocking density and microalgae concentration in diet on growth number competent larvae (number live at end experiment retained a sieve with mesh size 210 µm) Perna perna water recirculation system (RAS). The was conducted using completely randomized design factorial scheme, one factor being food three levels (low: between 1.26 to 2.19, medium: 2.36 3.94 high: 5.03 7.29 x 104 cells mL⁻¹) second culture density, also (20, 80 200 mL⁻¹), 3...
Na Indústria Alimentar, em particular na Aqüícola, a utilização de corantes tornou-se uma ferramenta indispensável conquista mercado, garantindo melhoria no aspecto e aumento da aceitação valor econômico seus produtos. A associação dos naturais às vantagens nutricionais sua obtenção por processos baixo custo têm reduzido pigmentos origem sintética Alimentar escala mundial. Desta forma, estudou-se eficiência três métodos extração carotenoídicos totais astaxantina das microalgas Chlorella...
Crassostrea is the most farmed oyster genus worldwide and has significant economic social impacts with environmental benefits. Hatchery seed production a highly costly phase, fluidized nursery system can help reduce this cost time. The present study evaluated survival growth of two species (Crassostrea gasar gigas) in bed bottle system. With C. gasar, experiments were performed; one tested three stocking densities other bialgae diets. gigas, experiment monoalgae an initial occupation 8.8%...
ABSTRACT Anomalocardia brasiliana is an intertidal filter-feeding clam that can accumulate enterobacteria, such as Escherichia coli, and consequently affect human health. Shellfish depuration a procedure which reduces microbiological contaminants; however, salinity time vary across species to adequately reduce bacteria load. To analyze the effect of on bioaccumulation E. coli by A. brasiliana, this study evaluated in animals artificially contaminated with coli. Each experimental group clams...
