Experimental culture of the river prawn Macrobrachium americanum larvae (Bate, 1868), with emphasis on feeding and stocking density effect on survival

Abstract

ABSTRACT. The cauque river prawn Macrobrachium americanum occurs along the Pacific coast of America. This prawn can grow to a large size, making it an interesting option for aquaculture production. Currently, supplies of juveniles are limited because hatchery and laboratory-reared larvae are difficult to raise. This study assesses larval survival for different combinations of stocking density and feeding from larvae cultivated in green water. From these combinations, larvae fed with Artemia nauplii and maintained at a density of 50 larvae L -1 had the highest survival.Keywords: Macrobrachium americanum, larval development, feeding, survival, prawn.Cultivo experimental de larvas de langostino Macrobrachium americanum (Bate, 1868), con énfasis en alimentación y efecto de la densidad sobre la supervivencia RESUMEN. El langostino de río Macrobrachium americanum, ocurre a lo largo de la costa Pacífica de América. Este langostino puede alcanzar grandes tallas lo que lo convierte en una opción interesante para la acuicultura. En la actualidad, el abastecimiento de juveniles a partir del cultivo de sus larvas en hatchery y en laboratorio son difíciles de criar. Este estudio evalúa la supervivencia de las larvas con diferentes combinaciones de alimento y densidades de población cultivadas en agua verde. A partir de estas combinaciones, las larvas alimentadas con nauplios de Artemia salina, mantenidas a una densidad de 50 larvas L -1 , tuvieron la mayor supervivencia.Palabras clave: Macrobrachium americanum, desarrollo larvario, alimentación, supervivencia, langostino.

Spermatophore production and sperm quality of the river prawn Macrobrachium americanum Spence Bate, 1868 fed with different diets

“…Recent investigations have focused mostly on production and nutrition of M . americanum juveniles (García‐Guerrero & Apún‐Molina, ; Méndez‐Martínez et al, , ; Pérez‐Rodríguez et al, ; Soberanes‐Yepiz et al, ; Yamasaki‐Granados et al, ). One of the main problems for the successful implementation of aquaculture of this river prawn is the typically low larval survival rate under culture conditions (Yamasaki‐Granados et al, ).…”

“…americanum juveniles (García‐Guerrero & Apún‐Molina, ; Méndez‐Martínez et al, , ; Pérez‐Rodríguez et al, ; Soberanes‐Yepiz et al, ; Yamasaki‐Granados et al, ). One of the main problems for the successful implementation of aquaculture of this river prawn is the typically low larval survival rate under culture conditions (Yamasaki‐Granados et al, ). Therefore, any attempt at cultivation would depend on the collection of wild specimens and the success of reproduction in aquaculture is closely related to the nutritional status of broodstock as an initial condition for reproduction (Bray & Lawrence, ; Racotta, Palacios, & Ibarra, ).…”

“…Cultivation of native species has been developed for the oriental river prawn Macrobrachium nipponense (De Haan, 1849) Molina, 2008;Méndez-Martínez et al, 2017Pérez-Rodríguez et al, 2018;Soberanes-Yepiz et al, 2018;Yamasaki-Granados et al, 2013). One of the main problems for the successful implementation of aquaculture of this river prawn is the typically low larval survival rate under culture conditions (Yamasaki-Granados et al, 2013).…”

“…Nutrition is one of the main factors that influences the status of crustacean sexual output, because it promotes gonad development and influences the morphological and physiological state of the gametes (Bray & Lawrence, 1992;Harlioğlu et al, 2013;Harrison, 1990;Wouters, Lavens, Nieto, & Sorgeloos, 2001;Yamasaki-Granados et al, 2013). The study of the effect of the reproductive condition of both parents on egg production and early survival of larvae is one of the most influential aspects for achieving commercial profits from river prawn aquaculture.…”

Effect of dietary protein content on growth rate, survival and body composition of juvenile cauque river prawn,Macrobrachium americanum(Bate 1868)

“…Wild prawns have already entered regional markets. Wild populations, at least along the coast of Mexico, are decreasing each year, particularly larger specimens (García‐Guerrero, Orduña‐Rojas & Cortés‐Jacinto ; Yamasaki‐Granados, García‐Guerrero, Vega‐Villasante, Castellanos‐León, Cavalli & Cortés‐Jacinto ). Wild populations have declined due to overharvesting, altered habitat and pollution (Yamasaki‐Granados et al .…”
