Bacteries associees aux production de Brachionus plicatilis

Kanazawa, A.

The mass production of penaeid larvae still depends on live foods such as diatoms, Chlorella and Artemia . However, it requires much facilities, maintenance expenses, and labor to produce a desired amount of life foods safely and constantly. Also, the nutritive value of planktonic organisms is occasionally variable and this makes the use of live food for mass culture restrictive. Therefore, it is necessary to develop microparticulate diets as a substitute for live foods to further increase the productivity of seed for shrimp culture.

Bacteria associated with semi-continuous culture of Brachionus plicatilis , which is used as the first food of marine fish larvae, were counted on Zobell 2216 E medium and identified. The numbers of bacteria were very high in both Brachionus (about 10 super(11) bact. per ml of digestive content) and in water (from 1.6.10 super(6) to 4.7.10 super(7) bact. per ml). The cultures were studied at driving a time when mortalities occurred frequently. The introduction of a Pseudomonas) phenon at a proportion of about 50% to the dominant microflora persisted in time and was little influenced by diet. It has been the cause of the repression of the Vibrio, Aeromonas group which was found in an unusually small proportion. It induced a lack of microflora diversity and...

Production of live prey for marine fish larvae

Effects of nutritional requirement of live food organisms on growth and survival of barramundi/seabass Lates calcarifer (Bloch) larvae.

Kraul, S.

Tropical marine fish larvae vary in their requirements for live planktonic food. Selection of live prey species for culture depends on larval size and larval tolerance of water quality. This report describes some of the cultured prey species, and their uses and limits as effective food for fish larvae. Methods are presented for the culture of phytoplankton, rotifers, copepods, and other live feeds.

Ecología trófica de la pescadilla de red, Cynoscion guatucupa (Pisces: Sciaenidae), en aguas del Atlántico sudoccidental.

Rimmer, M; Reed, A.

Larvae of barramundi (Lates calcarifer ) reared intensively in some Australian hatcheries have suffered periodic high mortalities which have been ascribed to nutritional deficiencies in the live food organisms used, particularly deficiencies of polyunsaturated fatty acids. Barramundi larvae reared in an experimental system and fed on four diets, representing combinations of supplemented and unsupplemented rotifers (Brachionus plicatilis ) and supplemented and unsupplemented brine shrimp (Artemia salina ). Supplementation of rotifers and brine shrimp with a commercially available microencapsulated diet increased the levels of several polyunsaturated fatty acids in the food organisms.

Régime alimentaire du diagramme gris "Plectorhynchus mediterraneus" (guichenot, 1850), (poisson, haemulidae) des côtes Mauritaniennes

García, S..

Trophic spectrum of Cynoscion guatucupa (striped weakfish) was analyzed through stomach content of individuals coming from two areas of Buenos Aires coast (38° 30'S - 41° 30'S): Argentine - Uruguayan Fishing Common Zone (AUFCZ) and El Rincón area (Argentine Sea, SW Atlantic). The stomach contents of 3323 individual captured in research cruises carried out during 2004 and 2005 was determined. In the diet 39 prey items were identified corresponding to 4 Phyla. Trophic spectrum was determined with Index of Relative Importance (IRI), where fishes were the principal prey (72,53 percentage IRI), crustaceans were secondary prey (27,44 percentage IRI) and with minor values polychaetes and mollusk (0,2 percentageIRI) were found. Pelagic fish was the predominant...

Ecología trófica del congrio de profundidad Bassanago albescens (Barnard, 1923) en el Atlántico Sudoccidental (35º'S-45º'S)

Sato, N.E..

Studied the effect of the predation of Noctiluca scintillans, Sagitta friderici and larvae of Engraulis anchoita in planktonic community of the coastal waters off Buenos Aires province from samples obtained of a permanent station EPEA (38°28’ S, 57°41’ W, 48 m depth) from March 2000 through April 2001. The composition of the diet of the three species predators considering appearances quantitative and qualitative was determined. It found that N. scintillans consumed mainly diatoms and copepod eggs. The alimentary index varied between 27.50% and 77.00%. The highest value corresponded to September, 2000. The analyses of the diets of S. friderici and of the larvae of E. anchoita indicated that both consume mainly different stages of development of the same...

Alimentación de Merluccius hubbsi e impacto del canibalismo en la región comprendida entre 34°50'-47°s del Atlántico Sudoccidental.

Aloui, N.; Amorri, M..

La saline de Sfax constitue le meilleur site pour l’exploitation et la production d’Artemia en Tunisie. La production de cystes est exploitée chaque année pour être utilisée dans l’alimentation des larves de poissons. Cette production est estimée à 30 kg de cystes poids sec. Toutefois, lors de nos campagnes de récolte, nous avons enregistré de grandes pertes de cystes occasionnées par les vents emportant les cystes qui seront mélangés avec le sable. Afin de minimiser les pertes et optimiser la production naturelle de la saline, nous avons jugé utile, d’installer des barrages dans les coins des bassins à Artemia pour s’opposer à l’action du vent. Par ailleurs, nous avons fait un suivi mensuel de l’abondance des cystes récoltés et de quelques paramètres...

Feeding of Argentine hake during winter 1994, between 50 and 370 m of depth, in the studied area (34°50'-47°S), is based on the consumption of zooplanktonic crustaceans, fishes and cephalopods. Maximum feeding incidence is found at 36°-40°S (51. ), in sea layer of 80-130 m deep (62. ) and between 8:00-10:00 hours (36,6. ). Cluster analysis shows five spatial groups, with similar length distributions and characteristic principal prey items combination. The males of all sizes show a trend to feed on euphausids and hiperiids amphipods. The females eat more quantities of hake, short fin squid and other fishes. There is a change in diet related with predator size, from 47 cm TL onwards for males, and from 53 cm TL for females. This change consists in a decrease...

The effect of supplemental ascorbic acid in enriched live food for Clarias gariepinus larvae at startfeeding

Merchie, G.; Lavens, P.; Verreth, J.; Ollevier, F.P.; Nelis, H.; De Leenheer, A.P.; Storch, V.; Sorgeloos, P..

The effect of three dietary ascorbic acid (AA) concentrations, each applied via two feed types, on production characteristics and physiological condition of African catfish (Clarius gariepinus) larvae has been assessed in two 10-day culture trials. Three treatments received only Artemia nauplii enriched with an experimental emulsion containing 0, 10 or 20% ascorbyl palmitate (AP) and yielding 530, 1200 and 1600 µg AA g-1 DW Artemia , respectively; the other three treatments were fed the same Artemia diets which were partially substituted by an artificial diet containing no vitamin C (ratio 20:80). No differences in survival could be observed: however, from...

In finfish mariculture, seed production and larval rearing still form the bottleneck for all ongrowing operations and are considered as the main limiting factor for industrial development. Through trial and error more than through biological understanding two opposite hatchery techniques have been developed which surprisingly control a multiparametric combination of different factors but aspire to the same objective of conformity with wild standards and the cost-effective production of larvae. In intensive aquaculture, the rearing technique is characterised by high initial larval densities in small tanks under strict hydraulic, thermic, and nutritional conditions. The light conditions are artificial. The temperature and quality of water are controlled. The...

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 Penaeus stylirostris. HUFA-rich or HUFA-enriched Artemia nauplii yielded higher production results in the hatchery than HUFA-poor Artemia 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 Artemia nauplii. Differences in production results could be attributed to the HUFA content in living and non-living larval diets.

Unlike Artemia nauplii which are used extensively as convenient live feed in aquaculture, large-scale utilization of Artemia juveniles and adults (biomass) is still very limited and in most cases restricted to those operations which are located near an Artemia production site. Currently applied techniques for preservation of Artemia biomass (e.g. blast-freezing or drying) are often cost prohibitive and in several cases not applicable at the remote and scattered sites where the Artemia biomass is available. An inexpensive technique which can be readily applied under field conditions and allowing to stabilize and retain the nutritional quality of...

Although there exists an obvious inclination to replace live larval food by formulated feeds, Artemia nauplii are still essential in the larviculture of marine fish species. So far, on-grown Artemia are rarely used in larviculture although they offer several advantages over Artemia nauplii: e.g. they contain a higher individual protein and energy content thus improving the fish larvae's energy budget; an equal amount of live food is reached with far less individuals thus a considerable saving of Artemia cysts; their composition of (n-3) highly unsaturated fatty acids (HUFA) may easily be improved by applying enrichment techniques. This study deals with the development of...
