Three key factors for successful aquaculture are eggs, feeds, and water. The eggs need to be healthy and genetically advanced to exhibit fast growth, superior meat yield, disease resistance, and early maturation. Premium traits have been carefully selected and refined through generations (F1 and F2) to stabilize these desirable qualities for commercial applicat

Improvement of seed production by   SISP-B (Semi Intensive Seed Production with Balanidae) Abstract Wild captured cabrilla común ( Paralabrax humeralis ) spawn 19 million eggs and 9 million larvae hatch-out from November 2018 to April 2019. The spawning occurred water temperature 18 to 20 °C mainly. Several SISP （ Semi Intensive Seed Production ） were operated and improved the method. SISP method is different from intensive method as SISP feed natural growing wild copepod instead of rotifer and Artemia that create intensively. Thus SISP not only require several tanks and equipment (pump, filter, UV etc.) but also high level technique and experience. SISP makes anybody produce premium juvenile easily without large investment. Remarkably we found that the larvae eat picoroco nauplius ( Austromegabalanus psittacus ) which nauplius grows bigger and longer than copepod and blue mussel. Also produce picoroco nauplius easier than copepod that collect in coast and just hang in the SISP t

DESCRIPCIÓN DE LOS ESTADIOS DE DESARROLLO DE HUEVOS Y LARVAS EN SACO VITELINO DE LA CABRILLA COMÚN ( Paralabrax humeralis ) Jessica Pizarro1, Masatoshi Futagawa, German Bueno, Juan Pablo Díaz 1 Facultad Recursos Naturales Renovables. Universidad Arturo Prat. Iquique - Chile. jpizarro@unap.cl INTRODUCCIÓN La cabrilla común Paralabrax humeralis (Valenciennes, 1828) es un serránido que habita en áreas costeras rocoso-arenosas desde Ecuador (3° S) hasta la región austral de Chile (33°10' S). Es una especie valorada para el consumo humano en el mercado nacional   chileno, con tendencias decrecientes de su abundancia desde los 80’ de acuerdo a las estadísticas pesqueras. El conocimiento de los estados tempranos de vida de esta especie (e.g. características morfológicas, desarrollo embrionario, período de incubación) son desconocidos, constituyendo antecedentes importantes para el desarrollo de un proceso de repoblamiento. El objetivo de este estudio fue conocer y descr
