A research program was carried out to improve and facilitate rotifer (&lt;i&gt;Brachionus plicatilis&lt;/i&gt;) culturing as well as to assure their optimal nutritional quality as a prey, concentrating on the development of a dry and complete rotifer diet that does not require the use of algae and does result in a HUFA rich &lt;i&gt;Brachionus&lt;/i&gt;. The present poster provides results dealing with culture aspects and rotifer nutritional quality. Different diet compositions based on single cell proteins enriched with various nutritional additives were evaluated. Results obtained so far demonstrate that a selected formula of a combined culture and enrichment diet, that does not involve the use of microalgae at all, can be successfully used for growing...

The effect of broodstock diet on reproductive activity and offspring quality in the marine crustacean &lt;i&gt;Mysidopsis bahia&lt;/i&gt; (M.)
Provedor de dados: 27
Autores: Léger, P.; Ferraz de Queiroz, J.; Sorgeloos, P.
This paper describes the first results of a study on the effects of broodstock nutrition on reproduction in marine crustaceans. For this, a short-term test system has been developed with the estuarine mysid shrimp &lt;i&gt;Mysidopsis bahia&lt;/i&gt; (M.) as experimental animal. Three different &lt;i&gt;Artemia&lt;/i&gt; preparations were evaluated for their possible effects on reproductive activity and offspring quality: a commercial maturation diet (Marila) incorporated in Great Salt Lake &lt;i&gt;Artemia&lt;/i&gt; metanauplii was compared to freshly-hatched nauplii and coconut-oil enriched metanauplii as food sources for the experimental broodstock animals. Within an experimental period of 14 days after reaching sexual maturity, 3.4 respectively 8.8...

Freshly hatched San Pablo Bay and Great Salt Lake &lt;i&gt;Artemia&lt;/i&gt; nauplii (omega-3-HUFA-poor) and enriched meta-nauplii (omega-3-HUFA-enriched)were compared to reference &lt;i&gt;Artemia&lt;/i&gt; nauplii (omega-3-HUFA-rich) as a food source for the larvae of the sea bass, &lt;i&gt;Dicentrarchus labrax&lt;/i&gt;. Significant differences in survival and biomass production between the treatments could be attributed to the omega-3-HUFA content of the food. A delayed mortality in fish larvae fed the Great Salt Lake &lt;i&gt;Artemia&lt;/i&gt; is suspected to be caused by a high level of alpha-BHC in this &lt;i&gt;Artemia&lt;/i&gt; source. Growth was not significantly different between the treatments, most probably due to the large variation in growth...

Autores: Léger, P.; Vanhaecke, P.; Sorgeloos, P.
Freshly-hatched &lt;i&gt;Artemia&lt;/i&gt; nauplii from various geographical sources survived storage in a refrigerator (2-4°C) at densities of 2000 per ml and above. Except for &lt;i&gt;Artemia&lt;/i&gt; from Chaplin Lake and Buenos Aires, naupliar viability was very high even after 48 h storage, and did not decrease significantly after a 24 h post-storage transfer to 25°C. Neither the naupliar dry weight nor biochemical composition changed significantly during refrigeration for most strains tested. Comparative culture-tests with stored and freshly-hatched nauplii as food for juvenile marine mysids &lt;i&gt;Mysidopsis bahia&lt;/i&gt; M. and larval carp &lt;i&gt;Cyprinus carpio&lt;/i&gt; L. revealed similar production performances.

Samplings were organized in three marine fish hatcheries. Samples were taken at different steps during the production of algae, rotifers and &lt;i&gt;Artemia&lt;/i&gt; . There were 233 dominant colony types isolated for further characterization. The isolates were compared to each other and to reference strains of &lt;i&gt;Photobacterium, Vibrio&lt;/i&gt; and &lt;i&gt;Alteromonas&lt;/i&gt;, using cellular fatty acid fingerprints. Fatty acid profiles of the isolates were grouped using principal component analysis. The isolates fell into at least ten major groups, of which two correspond to the genera &lt;i&gt;Vibrio&lt;/i&gt; and to &lt;i&gt;Alteromonas&lt;/i&gt;, respectively. Some groups seem to be restricted to a particular type of live food or isolation...

Autores: Holmefjord, I.; Gulbrandsen, J.; Lein, I.; Refstie, T.; Léger, P.; Harboe, T.; Huse, I.; Sorgeloos, P.; Bolla, S.; Olsen, Y.; Reitan, K.I.; Vadstein, O.; Øie, G.; Danielsberg, A.
The larval stage is regarded to be the main bottleneck of halibut production. Halibut eggs were obtained from captive broodstock both by stripping and by natural spawning. Artificial photoperiods were used to increase the total spawning season. Yolk sac larvae are presently produced either in small stagnant units or in large flow through systems. A major consideration is to avoid stress of the larvae, caused by mechanical disturbances of the larvae and by high bacterial load or high ammonia levels in the water.The experimentation showed that halibut larvae began to ingest algae earlier than rotifers &lt;i&gt;Brachionus&lt;/i&gt; sp. Supplementation of algae to first feeding tanks resulted in enhanced survival and growth rate of the larvae. Both rotifers...

Autores: Léger, P.; Bieber, G.F.; Sorgeloos, P.
The importance of highly unsaturated fatty acids (HUFA) such as 20:5omega3 and 22:6omega3 has been investigated for the larvae of the blue shrimp &lt;i&gt;Penaeus stylirostris&lt;/i&gt;. HUFA-rich or HUFA-enriched &lt;i&gt;Artemia&lt;/i&gt; nauplii yielded higher production results in the hatchery than HUFA-poor &lt;i&gt;Artemia&lt;/i&gt; especially when yeast was used as a substitute for algae during the early larval stages. Best results were obtained when a HUFA-rich formulated diet was used as a supplement to the yeast and as an enrichment for the &lt;i&gt;Artemia&lt;/i&gt; nauplii. Differences in production results could be attributed to the HUFA content in living and non-living larval diets.

Autores: Komis, A.; Léger, P.; Sorgeloos, P.
The biochemical composition of fish eggs is often used as an indicator for assessing the nutritional requirements of aquaculture species during their larval stages. Fatty acids of the (n-3) HUFA type have proven to play a critical role in providing good growth, survival and stress resistance in marine fish larvae. Hence, analyzing these fatty acids in fish eggs may provide interesting data on the requirements for those essential nutrients. By comparing the analyses of wild versus broodstock fish eggs differences may appear, possibly explaining differences in egg quality. Intra-spawning-season differences may further appear by following fatty acid profiles in the course of time. Finally, the influence of broodstock nutritionon egg composition may be another...

The importance of essential fatty acids for the early larval stages of cultured marine fish and crustacean larvae is well documented. In this regard, the variability in essential fatty acid content of their live prey &lt;i&gt;Artemia&lt;/i&gt; is critical.This paper describes different techniques for improving the fatty acid profile in &lt;i&gt;Artemia&lt;/i&gt; nauplii using microparticles and emulsions as enrichment diets. These diets can be applied during the incubation of the cysts and/or after the separation of the nauplii. After enrichment, the nauplii not only contain high levels of the essential fatty acid 20:5 omega 3 (up to 13.5% or 35.2 mg/g) but also considerable levels of 22:6 omega 3 (up to 7% or 18.1 mg/g), another essential fatty acid which...

A new artificial diet for the early weaning of seabass (&lt;i&gt;Dicentrarchus labrax&lt;/i&gt;) larvae
Provedor de dados: 27
Autores: Devresse, B.; Candreva, P.; Léger, P.; Sorgeloos, P.
The weaning of marine fish larvae is a critical step in larval rearing. The successful transition from live food to an artificial feed depends among others on the quality of the dry feed used (e.g. freshness of ingredients, digestibility, quality of the formulation) and the larvae themselves (e.g. age, behaviour towards artificial diets, development of the digestive tract, efficiency of certain metabolic pathways). The present study shows the results obtained with a new artificial diet formulated for the weaning phase of marine fish larvae (&lt;i&gt;Dicentrarchus labrax&lt;/i&gt;) in commercial hatcheries.

The results are presented of preliminary trials conducted with &lt;i&gt;Tapes semiducussata&lt;/i&gt; spat using manipulated yeast products as substitutes for unicellular algae in their diets. Findings showed that spat growth increased with increasing amounts of algae in the artificial diet; growth was very poor when no algae were offered at all. It is concluded that manipulated yeasts may replace a substantial part of the algae in clam diets, but complete replacement is not possible, yet.

The development of a cost-effective algal substitute would greatly reduce operating costs of bivalve hatcheries and has therefore been the subject of many studies. Previous work has resulted in the development of a yeast diet with improved digestibility and nutritional composition. Preliminary trials showed that this diet can substitute up to 80% of the algal diet in the seed culture of the Manila clam &lt;i&gt;Tapes semidecussata&lt;/i&gt;. In this communication we propose a culture test diet which will be used to study further dietary improvements of the yeast product.Juveniles of the Manila clam (1 to 5 mg unit weight) were batch cultured in a 51 recirculating system. Optimal daily ration for the algal control diet &lt;i&gt;Chaetoceros...
