The present study evaluated various sodium and potassium concentrations in hatchery water to determine which proportions would be optimal for Macrobrachium rosenbergii larviculture. Using a closed RAS system (60‐L), experiments were conducted in two stages. In the first stage, larval quality parameters were compared among triplicate treatments of sodium (2000, 3000, 4000 and 5000 mg L−1) and potassium (100, 150, 200 and 250 mg L−1). During the second stage, these same parameters were compared from interactions of the two best concentrations determined in the first stage. Initial larval density was fixed at 100 larvae L−1 and larval quality parameters such as larval stage index (LSI), larval condition index (LCI), larvae dry weight, survival (%), LC50‐24 h for formalin stress and time of the first postlarvae (PL) appearance were measured. Results showed that during the early larval period time LSI, LCI and survival parameters were affected only by potassium and the interaction with sodium was not significant. At a later period of the larval development, interactions between both sodium and potassium were measurable for LSI (P < 0.05) while the interactions on LCI and survival were not significant. Measurable differences among the combined treatments 4000 mg L−1 sodium and 150 mg L−1 potassium resulted in the best performance for M. rosenbergii larviculture. This concentration also provided the highest final survival to PL metamorphosis (40.6 ± 2.5%) which was at least 10% higher than the other treatments.

“…Larval dry weights were determined at 1, 8 and 16 days post hatch (dph) in accordance with Nhan et al . (). Dry weight was obtained at 60°C for 48 h. Survival (%) was calculated at 10, 20 and 30 dph, and time of the first PL appearance was recorded in the treatments.…”

“…Studies using different stocking densities showed significant differences in survival; higher survival occurred at lower stocking density, but those studies used M. rosenbergii, which has larger larvae at hatching and has well established larval cultivation techniques (100 larvae L -1 Macrobrachium rosenbergii; Nhan et al, 2009), showing that density heavily affects larval survival at high stockings (Graçá-Melo & Brossi-Garcia, 2005). Nhan et al (2009), found that densities over 200 are critical since tolerance to stress and starvation decreases at higher densities. According to these authors, recommendable densities are about 100 larvae L -1 ; low densities imply more available nauplii per larvae, but also more surplus nauplii in the culture which negatively affects water quality and has a negative effect on survival (Lavens et al, 2000).…”

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.

Growth performance and survival of giant freshwater prawn Macrobrachium rosenbergii larvae fed coloured feed

et al. 2018

View full text Add to dashboard Cite

This study examined the behavioural response on the preference and acceptance, growth performance and survival of Marcobrachium rosenbergi larvae fed with isonitrogenous and isolipidic yellow (YCF) and blue (BCF) coloured feed. In the behavioural response test, single and paired feed drop test of YCF and BCF were introduced at the middle of a tank about 15-20 cm from the edge of the white colour tank wall to larvae zoea IV-VI. The number of larvae attracted to each coloured feed was recorded. For the growth and survival performance, each coloured feed was fed to triplicate groups of larvae (zoea V-VI) at stocking density of 30 larvae/L in 12 ppt brackish water for 28 days until they reached postlarval (PL) stage. In the behavioural test, the number of larvae that attracted and accepted the BCF was significantly higher than those fed YCF (p < 0.05). The body weight and length of PL fed BCF was 28% and 5.6% bigger than those fed YCF respectively. However, the survival of the PL was almost similar in both treatments. This study shows that the freshwater prawn larvae were attracted more to the BCF and able to detect and capture the preferred BCF by vision and this contributed to higher growth of the larvae.
