Abstract To optimize the conditioning procedure to obtain better larvae with lower production costs, Ruditapes decussatus broodstock was conditioned at different periods during the year [October (C1), February (C2), and April (C3)] under two different controlled temperature regimes: a constant temperature (CT, 20°C) and a gradual increase in temperature from ambient to 20°C (GT). Samples (30 adult clams) were collected randomly every month from a control group and from each conditioning tank (three tanks for each temperature treatment). A section of the gonad-visceral mass was sampled for gonadal histology and the remaining tissue was used for biochemical analyses. Gonadal developmental stages were determined based on the classification proposed by Wilson and Seed (1974), and fertilized eggs were reared after the method of Walne (1966). In the three conditioning experiments fewer degree-days were required to successfully spawn clams in tanks with the gradual increase of temperature. Clams conditioned in O...

This article describes the effects of food availability on the sexual maturation of Ruditapes decussates through histological examination of the gonadal tissue. Three food rations were tested: High (H: 1 mg. organic matter. g live weight –1 .day -1 of the microalgae Isochrysis galbana clone T-ISO), intermediate (I: 0.5 mg OM g live weight -1 day -1 ) and nutritionally restricted (R: 0.25 mg OM g live weight -1 day -1 ). The tests were carried out at a constant temperature of 18°C for a period of...

A comparative study ofthe reproductive cycle o/'Ruditapes decussatus under natural(South ofTunisia) and con­ trolled conditions (hatchery). The aim of this study was to describe and compare the gametogenic activity of Ruditapes decussatus in situ and in hatchery. Criteria of maturity were characterized and the positive role of conditioning in the suc­ cess of artificial reproduction was underlined. Specimens sampled in the South of Tunisia were conditioned at the experi­ mental station of Monast...

Abstract Seasonal variations in the body weight and biochemical composition of the bivalve Ruditapes decussatus were studied over a period of 15 months. Separate analyses were made of foot, mantle edge, siphons, gills, adductor muscle and gonad-visceral mass. Variations in weight, body growth, gonad growth and spawning depended on environmental conditions, especially food availability. The gametogenic cycle comprised two phases: a resting phase (November–December) and gametogenesis, including ri...

Abstract Adult specimens of Argopecten purpuratus, obtained from Culture Centers of Tongoy Bay (Region IV, North of Chile), were conditioned at two temperatures, 16°C and 20°C, and three different diets: a mixture of pure microalgae, microalgae mixed with lipids and microalgae mixed with carbohydrates. Daily food supply was 6% of dry biomass. Three replicate tanks were assayed for each treatment. The progress of gonadal recovery was followed by periodic determination of gonadic index and histolo...

This paper presents a summary of information on reproduction biology in the scallop, Pecten maximus, which is required for the successful reseeding and intensive aquaculture programs developed in France since 1982. Data are presented on the following subjects: environmental factors that sustain gametogenic activity and the time of year this activity occurs; biochemical changes that are associated with gametogenesis; the consistency of egg quality; and development of a simple test to predict egg ...

Abstract Artificial conditioning of broodstocks of Mercenaria mercenaria L. and Crassostrea virginica (Gmelin) was initiated at various times throughout the year under both laboratory and commercial hatchery conditions. Attempts were made to spawn broodstocks at weekly intervals, and data were collected on the initial total egg lipid content of eggs by analytical procedures and by visual inspection after staining with Oil Red O. The physical parameters of egg diameter and density (estimated by d...

Aquaculture and capture production of clam species have great economic value in Europe. The production is dominated by the introduced species, Manila clam, Ruditapes philippinarum, which has displaced some of the native species of clams. In Europe, landings of autochthonous clams have decreased in the recent years due to overfishing, failure in recruitment, abiotic stress and diseases. Due to aforementioned factors, seed production in hatcheries has become essential to ensure the sustainability ...

Studies considering broodstock conditioning of Ruditapes decussatus mostly used flagellates and diatoms for feeding, mainly Isochrysis galbana and Chaetoceros calcitrans, respectively. The present study evaluated the effect of different microalgal diets on gonadic maturation of R. decussatus including three microalgae species (C. calcitrans, Tetraselmis suecica, and Nannochloropsis oculata) which were used to prepare six diets: three monospecific and three bispecific mixed diets at a proportion ...

Hatcheries constitute nowadays the only viable solution to support the husbandry of bivalve molluscs due to the depletion and/or overexploitation of their natural beds. Hatchery activities include the broodstock conditioning and spawning, rearing larvae and spat, and the production of microalgae to feed all stages of the production cycle. However, outbreaks of disease continue to be the main bottleneck for successful larval and spat production, most of them caused by different representatives of...

Geoduck clams are amongst the most valuable cultured shellfish available on the world market, driving interest in the establishment of the native New Zealand species, Panopea zelandica (Quoy & Gaimard, 1835), as a candidate for aquaculture. A critical element of domestication is the effective management of breeding stock to optimize gamete and offspring quality. To develop a reliable broodstock conditioning protocol for P. zelandica, we investigated the biochemical composition of geoducks expose...

Diseases caused by bacteria belonging to the genus Vibrio are a common, as yet unresolved, cause of mortality in shellfish hatcheries. In this study, we report the results of routine microbiological monitoring of larval cultures of the carpet shell clam Ruditapes decussatus in a hatchery in Galicia (NW Spain). Previous episodes of mortality with signs similar to those of vibriosis affecting other species in the installation indicated the possibility of bacterial infection and led to division of ...

AbstractVenerupis corrugata is commercially exploited in Europe. Over-fishing and recruitment failure is causing the decline of its populations and stock sustainability. Knowledge of this species reproduction is paramount to establish hatchery production of juveniles for restoring natural beds. This work aimed to find a relationship between broodstock condition, oocyte quality, and viability of 24 h D-larvae. Adult specimens were induced to spawn by thermal stimulation. From each female, oocytes...

Abstract Broodstock conditioning in hatcheries is the step previous to spawning and its optimization may be a key to the success of larval cultures. Cleaning and brushing of the broodstock and the utilization of antibiotics to reduce their vibrios load are used regularly as routine prophylactic measures prior to spawning induction. The development of protocols to reduce these bacteria using cheap and harmless techniques is of utmost importance for commercial bivalve production in hatcheries. Wit...

The surf Spisula solida and the striped venus Chamelea gallina clams support important fisheries in Europe. These fisheries have been affected by inter-annual fluctuations in stock abundance and recruitment failures. Aquaculture could contribute to address these problems through the production of larvae or juveniles for stock-enhancement programmes. In the present study, the prerequisites to produce these species in hatchery were established. Of the different methods used to obtain gametes (ther...

AbstractRuditapes decussatus is a species of importance to aquaculture. For hatcheries to consistently produce spat it is essential to develop broodstock conditioning techniques. Food and temperature are the main factors that regulate the timing and rate of energy storage and reproduction in bivalves. This study was designed to evaluate the effects of different diets and temperatures on reproductive output of R. decussatus and express the evolution of the different lipid classes during sexual ma...
