Abstract
Amino acids are the building blocks for growth and the major energy source during fish larval stages. Deficient amino acids can be supplemented in the diets, overcoming problems such as low growth rates and skeletal deformities. In this study, three experimental diets were tested: a balance diet supplemented with lysine, a balance diet supplemented with tryptophan and a control with no supplementation. Trials were conducted with Diplodus sargus larvae from 1 to 25 days after hatching (DAH). A microencapsulated diet was introduced at 15 DAH in co‐feeding with live feed and from 20 DAH larvae were fed only this diet. The effect of the supplemented diets was assessed in terms of survival, growth rate, skeletal deformities, ammonia excretion and activity of amino acid catabolism enzymes. The results showed a similar survival in all treatments. However, larvae given tryptophan supplementation had a lower weight on 25 DAH. No significant differences were found in ammonia excretion, frequency or type of deformities or enzymatic activity. Tryptophan and lysine supplementation failed to improve larval growth, survival or larval quality.

The results showed a similar survival in all treatments. However, larvae given tryptophan supplementation had a lower weight on 25 DAH. No significant differences were found in ammonia excretion, frequency or type of deformities or enzymatic activity. Tryptophan and lysine supplementation failed to improve larval growth, survival or larval quality.</p></abstract></abstractGroup></contentMeta></header></component></istex:document></istex:metadataXml><mods version="3.6"><titleInfo lang="en"><title>Supplementation of tryptophan and lysine in Diplodus sargus larval diet: effects on growth and skeletal deformities</title></titleInfo><titleInfo type="abbreviated" lang="en"><title>Tryptophan and lysine in Diplodus sargus larval diet</title></titleInfo><titleInfo type="alternative" contentType="CDATA" lang="en"><title>Supplementation of tryptophan and lysine in Diplodus sargus larval diet: effects on growth and skeletal deformities</title></titleInfo><name type="personal"><namePart type="given">Margarida</namePart><namePart type="family">Saavedra</namePart><affiliation>Instituto Nacional de Investigação Agrária e das Pescas (INIAP/IPIMAR‐CRIPSul), Olhão, Portugal</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Yoav</namePart><namePart type="family">Barr</namePart><affiliation>Nofima Marin, Sunndalsora, Norway</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Pedro</namePart><namePart type="family">Pousão‐Ferreira</namePart><affiliation>Instituto Nacional de Investigação Agrária e das Pescas (INIAP/IPIMAR‐CRIPSul), Olhão, Portugal</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Synnove</namePart><namePart type="family">Helland</namePart><affiliation>Nofima Marin, Sunndalsora, Norway</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Manuel</namePart><namePart type="family">Yúfera</namePart><affiliation>Instituto de Ciencias Marinas Andalucia (CSIC), Puero Real, Spain</affiliation><affiliation>CCMAR, Universidade do Algarve, Campus Gambelas, Faro, Portugal</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Maria T</namePart><namePart type="family">Dinis</namePart><affiliation>CCMAR, Universidade do Algarve, Campus Gambelas, Faro, Portugal</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Luís E C</namePart><namePart type="family">Conceição</namePart><affiliation>CCMAR, Universidade do Algarve, Campus Gambelas, Faro, Portugal</affiliation><role><roleTerm type="text">author</roleTerm></role></name><typeOfResource>text</typeOfResource><genre type="article" displayLabel="article"></genre><originInfo><publisher>Blackwell Publishing Ltd</publisher><place><placeTerm type="text">Oxford, UK</placeTerm></place><dateIssued encoding="w3cdtf">2009-07</dateIssued><copyrightDate encoding="w3cdtf">2009</copyrightDate></originInfo><language><languageTerm type="code" authority="rfc3066">en</languageTerm><languageTerm type="code" authority="iso639-2b">eng</languageTerm></language><physicalDescription><internetMediaType>text/html</internetMediaType><extent unit="figures">3</extent><extent unit="tables">6</extent><extent unit="formulas">1</extent><extent unit="references">53</extent><extent unit="words">7715</extent></physicalDescription><abstract lang="en">Amino acids are the building blocks for growth and the major energy source during fish larval stages. Deficient amino acids can be supplemented in the diets, overcoming problems such as low growth rates and skeletal deformities. In this study, three experimental diets were tested: a balance diet supplemented with lysine, a balance diet supplemented with tryptophan and a control with no supplementation. Trials were conducted with Diplodus sargus larvae from 1 to 25 days after hatching (DAH). A microencapsulated diet was introduced at 15 DAH in co‐feeding with live feed and from 20 DAH larvae were fed only this diet. The effect of the supplemented diets was assessed in terms of survival, growth rate, skeletal deformities, ammonia excretion and activity of amino acid catabolism enzymes. The results showed a similar survival in all treatments. However, larvae given tryptophan supplementation had a lower weight on 25 DAH. No significant differences were found in ammonia excretion, frequency or type of deformities or enzymatic activity. Tryptophan and lysine supplementation failed to improve larval growth, survival or larval quality.</abstract><subject lang="en"><genre>keywords</genre><topic>Diplodus sargus</topic><topic>amino acids</topic><topic>tryptophan</topic><topic>lysine</topic><topic>ammonia</topic><topic>skeletal deformities</topic><topic>growth</topic></subject><relatedItem type="host"><titleInfo><title>Aquaculture Research</title></titleInfo><genre type="journal">journal</genre><identifier type="ISSN">1355-557X</identifier><identifier type="eISSN">1365-2109</identifier><identifier type="DOI">10.1111/(ISSN)1365-2109</identifier><identifier type="PublisherID">ARE</identifier><part><date>2009</date><detail type="volume"><caption>vol.</caption><number>40</number></detail><detail type="issue"><caption>no.</caption><number>10</number></detail><extent unit="pages"><start>1191</start><end>1201</end><total>11</total></extent></part></relatedItem><identifier type="istex">CF2D139BD1CE5A543429A2308966F6CE7F2784CD</identifier><identifier type="DOI">10.1111/j.1365-2109.2009.02219.x</identifier><identifier type="ArticleID">ARE2219</identifier><accessCondition type="use and reproduction" contentType="copyright">© 2009 The Authors.
