Available in PDF, EPUB and Kindle. Book excerpt: Plans for an International Symposium on the Early Life History of Fish were first discussed in 1967 at the F. A. O. Advisory Committee on Marine Resources Research {A. C. M. R. R. }. It was considered that studies on fish eggs and larvae were of value in estimating the size of fish stocks, in appraising the stock-recruitment relationship, and in helping to answer questions on the systematics and taxonomy of fish. An A. C. M. R. R. Working Party recommended in 1969 that a Symposium should be held and after discussion with the International Associa tion of Biological Oceanography {I. A. B. O. } Dr. J. H. S. Blaxter of the Scottish Marine Biological Association {S. M. B. A. } agreed to con vene the meeting with the help of a steering committee. Various in ternational agencies were interested in the meeting and agreed to sponsor it in various ways. These agencies included F. A. O. , I. A. B. O. , the International Council for the Exploration of the Sea {I. C. E. S. } and the Scientific Committee for Oceanic Research {S. C. O. R. }. In the final event F. A. O. supported the meeting by publishing the abstracts beforehand, providing travel funds for participants and publishing a report after the meeting. I. A. B. O. and S. C. O. R. provided travel funds and the Royal Society of London and S. M. B. A.

Available in PDF, EPUB and Kindle. Book excerpt: As the expansion in world aquaculture continues at a very high rate, so does the need for information on feeding of cultivated fish and shellfish. In the larval and juvenile phases of many species, the use of manufactured feed is not possible. This important book covers in detail the biology and culture of the main live prey and microalgae used as feeds in the aquaculture of major commercial species including shrimps, sea bass, halibut, cod and bivalves. Contents include comprehensive details of the status of marine aquaculture in relation to live prey, and chapters covering the biology, production, harvesting, processing and nutritional value of microalgae and the main prey species: rotifers, Artemia and copepods. The editors have drawn together an impressive international team of contributors, providing a work that is set to become the standard reference and practical guide on the subject for many years to come. Live Feeds in Marine Aquaculture is an essential purchase for anyone involved in marine aquaculture, including fish farmers, researchers, and personnel in feed and equipment companies supplying the aquaculture trade. An extremely valuable tool as a reference and practical manual for students and professionals alike; libraries in all universities and research establishments where biological and aquatic sciences and aquaculture are studied and taught, should have copies available on their shelves.

Download or read book The Effect of Secondarily Enriched Rotifers on Growth and Survival of Marine Fish Larvae written by Gideon Minkoff and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutritional aspects of three species of marine fish larvae, herring Clupea harengus L., plaice Pleuronectes platessa L. andturbot, Scophthalmus maximus L. were examined. Larvae were fed three different diets all of which were derived from rotifersBrachionus plicatilis (O.F. Mtlller). These rotifers had been mass cultivated on baker's yeast and then enriched with baker's yeast, or with one of two unicellular algae, Isochrysis galbana Park or Nannochloropsis (Nannochloris) oculata (Droop) Hibberd. The biochemical changes that these enrichments conferred on the rotifer were examined. There was little difference inproximate and amino acid compositions. Dry weights, and calorific contents of the rotifers fluctuated according to the type, temperature and duration of enrichment, with the yeast enriched rotifers tending to weigh less (200-320 ng) than their algalcounterparts (250-370ng). Major differences were found in the total fatty acid profiles of the rotifers. Yeast-enriched rotifershad no 18:3n-3 or 20:5n-3 and only trace amounts of 22:6n-3 fatty acids. The Nanrinochioropsis-enriched rotifers had substantial amounts of n-3 fatty acids though only of 20:5n-3 (11-14%), whilerotifers enriched with Isochrysis had only trace amounts of 20:5n-3 (2-4%). All three species of fish responded similarly to the yeast enriched rotifer diet. Their growth, in terms of length and weight, was minimal and they never developed any fin ray elements. Both flatfishes developed a looped gut in the short growth duration on this diet and some turbot (20%) inflated their swim bladder. This retardation of growth was attributed to the lack of long chain highlyunsaturated n-3 fatty acids (n-3 HUFA) in the diet. During one month feeding trials it was shown that herring and plaice were able to exploit both algal-enriched rotifer diets equally well. Turbot, on the other hand grew better, over 14 days, on rotifers enriched with lsochrysis compared with Nannochioropsis. The reaction of the different species was linked to the fatty acid profiles of the diet. Hence, turbot require a dietary input of 22:6n-3 while herring and plaice thrived equally well on diets containing only 20:n-3. Juvenile plaice consistently exhibited improved pigmentation when Isochrysis compared to Nannochloropsis were used as therotifer enrichment. The effect was attributed to specific nutrients particular to algal chloroplasts, which need to be present in the diet of the larvae up to metamorphosis. Assessment of daily rations, employing the rotifer enriched with Isochrysis diet only, showed herring to reduce their food intakefrom 46 to 19% body dry weight/d between days 10-21 post hatch while turbot consumed between 34-169% body dry weight/d with noapparent age related effects. The gross growth efficiencies (Ki, Brett & Groves, 1979) for both species were seemingly unaffected by age related processes and fluctuated between 15-50% in turbot and 20-61% in herring according to fluctuations in daily food intake. Ingestion is further described for both species with a linear model that related food intake to larval weight. The weight-specific ingestion was found to be a constant 13% and 43% of body dry weight in herring and turbot respectively. The weight-specific ingestion and specific growth rate estimates were combined with other data available from the literature, revealing that larvae tendto consume food (in dry weight) at a level equivalent to approximately twice their daily dry weight increase.
