| contents | A first experience of Patagonian sprat Sprattus fuegensis spawning in captivity: Adult acclimation, egg and larval measurements Elson Leal Carlos Muñoz Guillermo Moyano Claudio Bernal Antonio Aranis Ciencias de la Tierra egg larvae captivity Sprattus fuegensis Relevant traits of eggs and larvae of Patagonian sprat ( Sprattus fuegensis ), obtained from adult reproduction in captivity conditions, were studied. Temperature for adult acclimation and for incubation of eggs and larvae wa s not controlled; however it ranged with a mean of 13 ± 2 °C. Adult sprat maintained in cylindrical ponds of 2000-L spawned spont aneously at the first night after catch, probably due to catch stress. The eggs were spherical with a diameter ranging between 0 .89 and 1.06 mm (mean 1.00 ± 0.05 mm, n= 54). The larvae hatched between the fourth and fifth day after spawning and their size varied between 2.83 and 4.11 mm long (mean 3.56 ± 0.34 mm, n= 39). The yolk sac reached a volume of between 0.11 and 0.22 mm 3 (mean 0.18 ± 0.033 mm 3 , n= 32) and was exhausted by the third day post hatching (dph). Larval growth only occurred during the e ndogenous feeding period (efp) and survival did not exceed 6 dph, probably due to inappropriate conditions for feeding and gr owth. 2017 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47954027021 en 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.52 |
