- Inducción al desove de la navaja Ensis macha mediante inyección de serotonina Daniel Arriagada Irene Lépez Maryori Ruiz Ingrid Contreras Ciencias de la Tierra spawning serotonin Ensis macha The effect of serotonin spawning stimulating agent, was evaluated in Ensis macha sexually mature broodstock, conditioned in laboratory. Neurotransmitter 0.9 ml at a concentration of 10 -5 M was injected into the foot of each specimen. 5-HT induced gamete release in 92% of injected broodstock, always producing the fastest response in males, removing sperm at 36 min (± 15.9) after injection. The release of mature oocytes began at 170 min (± 42.4) post-injection. Embryonic development to the veliger larva formation, straight hinge D had a survival of 88%, no malformations have been observed in larvae. In only one trial, fertilized oocytes were not viable. Finally, we can confirm that there is a pattern in the release of mature gametes E. macha broodstocks due to the action of serotonin 5-HT and could be a useful tool for aquaculture pr actices. 2013 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47929283023 es http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.3 Vol.48
