The sand beds were supplied with seawater at 30-ppt salinity and the nectochaetes reared for five months after which time some adults were becoming epitokes. The culture method yielded 3–4 kg polychaetes at an atokous stage per m of culture area. Because the polychaetes were to be used to feed shrimp broodstock, samples of the worms were screened for the presence of white-spot syndrome and yellow-head viruses using polymerase chain reaction (PCR) methods prior to introduction to the system as founders and at monthly intervals during their culture. Morphological details of P. cf. nuntia from fertilization to nectochaete stage are described using light microscopy, transmission (TEM) and scanning electron microscopy (SEM). The egg is surrounded by a chorion layer, TEM reveals that the microvillous tip vesicles are putative sites for the binding of the sperm to the egg surface. TEM studies of the cortical reaction show that the cortical alveoli contain a fibrous substance which, after fertilization and membrane fusion, passes into the perivitelline space to form part of the fertilization membrane, as well as being secreted from the egg surface to form a jelly layer surrounding the egg.","author":[{"@context":"https://schema.org","@type":"Person","name":"Kanokpan

cf. nuntia, a tropical species endemic in Thailand, was cultured in captivity as follows: eggs and sperm from sexually mature (epitokous) P. cf. nuntia, were artificially fertilized, and settled into a sand bed about 30 cm deep at the nectochaete stage. The sand beds were supplied with seawater at 30-ppt salinity and the nectochaetes reared for five months after which time some adults were becoming epitokes. The culture method yielded 3–4 kg polychaetes at an atokous stage per m of culture area. Because the polychaetes were to be used to feed shrimp broodstock, samples of the worms were screened for the presence of white-spot syndrome and yellow-head viruses using polymerase chain reaction (PCR) methods prior to introduction to the system as founders and at monthly intervals during their culture. Morphological details of P. cf. nuntia from fertilization to nectochaete stage are described using light microscopy, transmission (TEM) and scanning electron microscopy (SEM). The egg is surrounded by a chorion layer, TEM reveals that the microvillous tip vesicles are putative sites for the binding of the sperm to the egg surface. TEM studies of the cortical reaction show that the cortical alveoli contain a fibrous substance which, after fertilization and membrane fusion, passes into the perivitelline space to form part of the fertilization membrane, as well as being secreted from the egg surface to form a jelly layer surrounding the egg.","publication_date":"2007,,","publication_name":"Invertebrate Reproduction \u0026 Development"},"document_type":"paper","pre_hit_view_count_baseline":null,"quality":"low","language":"en","title":"Culture and development of the polychaete Perinereis cf. nuntia","broadcastable":false,"draft":null,"has_indexable_attachment":false,"indexable":true}}["work"]; window.loswp.workCoauthors = [34271684]; window.loswp.locale = "en"; window.loswp.countryCode = "SG"; window.loswp.cwvAbTestBucket = ""; window.loswp.designVariant = "grid"; window.loswp.fullPageMobileSutdModalVariant = "control"; window.loswp.useOptimizedScribd4genScript = false; window.loswp.appleClientId = 'edu.academia.applesignon';</script><script defer="" src="https://accounts.google.com/gsi/client"></script><div class="loswp-grid--container"><div data-auto_select="false" data-client_id="331998490334-rsn3chp12mbkiqhl6e7lu2q0mlbu0f1b" data-landing_url="https://www.academia.edu/15211920/Culture_and_development_of_the_polychaete_Perinereis_cf_nuntia" data-login_uri="https://www.academia.edu/registrations/google_one_tap" data-moment_callback="onGoogleOneTapEvent" id="g_id_onload"></div><div class="above-fold js-swp-splash-above-fold"><div class="work-card--container js-swp-control-work-card" data-entity-id="15211920"><div class="work-cover--wrapper"><div class="work-cover--container"><div class="work-cover--no-attachment-container js-swp-splash-paper-cover"><div class="work-cover--file-icon-wrapper"><img alt="paper cover icon" src="//a.academia-assets.com/images/single_work_splash/adobe.icon.svg" /></div><div class="work-cover--title js-swp-splash-paper-cover-page-title">Culture and development of the polychaete Perinereis cf. nuntia</div><br /><div style="margin-top: 170px"><button class="work-cover--request-pdf-button js-request-pdf-button"><svg style="width: 14px; margin-right: 8px;" aria-hidden="true" focusable="false" data-prefix="fas" data-icon="envelope" class="svg-inline--fa fa-envelope fa-w-16" role="img" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512"><path fill="currentColor" d="M502.3 190.8c3.9-3.1 9.7-.2 9.7 4.7V400c0 26.5-21.5 48-48 48H48c-26.5 0-48-21.5-48-48V195.6c0-5 5.7-7.8 9.7-4.7 22.4 17.4 52.1 39.5 154.1 113.6 21.1 15.4 56.7 47.8 92.2 47.6 35.7.3 72-32.8 92.3-47.6 102-74.1 131.6-96.3 154-113.7zM256 320c23.2.4 56.6-29.2 73.4-41.4 132.7-96.3 142.8-104.7 173.4-128.7 5.8-4.5 9.2-11.5 9.2-18.9v-19c0-26.5-21.5-48-48-48H48C21.5 64 0 85.5 0 112v19c0 7.4 3.4 14.3 9.2 18.9 30.6 23.9 40.7 32.4 173.4 128.7 16.8 12.2 50.2 41.8 73.4 41.4z"></path></svg>Request PDF</button></div></div></div></div><div class="work-card--content"><h1 class="work-card--title">Culture and development of the polychaete Perinereis cf. nuntia</h1><div class="work-card--pub-info">Invertebrate Reproduction & Development, 2007</div><div class="work-card--authors-container js-work-toolbar-work-owner"><div class="work-card--author-blurb"><div class="work-card--author-photo-wrapper"><a href="https://independent.academia.edu/KanokpanWongprasert"><img class="Avatar--circle s65 Avatar--xxxs" shape="circle" border="0" alt="" src="//a.academia-assets.com/images/s65_no_pic.png" /></a></div><div class="work-card--author-name-wrapper" style="max-width: 125px;"><a class="u-linkUnstyled u-fw500 u-textTruncate ds2-5-body-sm ds2-5-body-link" href="https://independent.academia.edu/KanokpanWongprasert" swp="tc-au-15211920">Kanokpan Wongprasert</a></div></div><div class="work-card--author-blurb"><div class="work-card--author-photo-wrapper"><img class="Avatar--circle s65 Avatar--xxxs" shape="circle" border="0" alt="" src="//a.academia-assets.com/images/s65_no_pic.png" /></div><div class="work-card--author-name-wrapper" style="max-width: 125px;"><div class="u-fontStyleItalic u-textTruncate">Prasert Sobhon</div></div></div></div><div class="work-card--no-attachment-details"><div style="font-weight: 700; font-size: 14px;">Abstract</div><div class="work-card--abstract js-swp-splash-abstract">ABSTRACT The polychaete Perinereis cf. nuntia, a tropical species endemic in Thailand, was cultured in captivity as follows: eggs and sperm from sexually mature (epitokous) P. cf. nuntia, were artificially fertilized, and settled into a sand bed about 30 cm deep at the nectochaete stage.
