“…The shortest body length at eclosion known in pleuronectiformes is 1.3 mm in Achirus mazatlanus, which has a short egg stage of 4 days (Ortíz-Galindo et al, 1990). A similar hatching size to that recorded for the Symphurus genus is found in Paralichthys californicus and Paralichthys dentatus, which ranges between 1.8 and 2.3 mm, and they have an egg stage of 4 to 5 days (Conklin et al, 2004;Watanabe and Feeley, 2004). In addition, the body length of preflexion larvae in this study ranged from 2.2 to 4.8 mm (AcevesMedina et al, 1999).…”

This study evaluated weaning success of California halibut, Paralichthys californicus, larvae onto a microdiet at various stages of development utilizing growth, survival and digestive enzyme activity. Weaning onto a microdiet was evaluated at 16, 26, 36 and 46 days posthatch (dph). Alkaline and acid proteases and leucine aminopeptidase activities were measured after weaning and compared between the weaned treatment and Artemia‐fed controls. Survival was significantly lower in the microdiet‐fed treatments compared to the control groups. Growth was significantly reduced in all weaning treatments compared to the control, except for the 46 dph group. No differences in enzyme activities were detected between treatment and diet at 16 and 26 dph; however, activities were higher for the microdiet‐fed larvae at 36 and 46 dph. This study demonstrates that California halibut larvae possess a differentiated and effective digestive system early in development and can be weaned with relative success (>40% survival) before completion of the metamorphosis (i.e., 36 dph). The lack of weaning success at an early date cannot be entirely because of the absence of a functional stomach but could be related to, among other factors, the low‐microdiet ingestion rates observed and higher leaching of smaller microdiets.

ABSTRACT. The present study describes the methodology used at IMARPE for the capture, acclimation and management of P. adspersus broodstock using recirculating aquaculture systems (RAS). RAS improved the water quality and maintained the environmental parameters during the acclimation period, temperature (17.2±1ºC), oxygen (8.1±0.7 mg L -1 ), pH (7.3±0.2), ammonia (0.004±0.003 mg L -1 ), nitrite (0.52±0.2 mg L -1 ) and nitrate (3.45±2.6 mg L -1 ). Fish began to be fed normally from day 15 post-capture, once or twice a day using live fish (Odonthestes regia regia, Mugil cephalus), crustacean (Emerita analoga), fresh food (Engraulis ringens and Dosidicus gigas) and artificial feed. A significant loss in the weight of the fish was registered during the first days of captivity, followed by a continuous increase in both sexes. The specific growth rate was positive from the third month of captivity, being the relative growth rate 24.5% and 16.2% in August 2010 in males and females, respectively. Different internal and external parasites were detected in the fish, being Entobdella sp. and Philometra sp. the prevailing parasites observed during samplings.

Manejo de reproductores del lenguado Paralichthys adspersus (Steindachner, 1867)usando sistemas de recirculación en acuicultura RESUMEN. El presente trabajo, describe la metodología desarrollada en IMARPE para la captura, aclimatación y acondicionamiento de ejemplares adultos de P. adspersus en sistemas de recirculación (SRA), con la finalidad de formar un stock de reproductores. El SRA permitió manejar parámetros medioambientales estables durante el periodo de acondicionamiento, como: temperatura del agua (17,2±1ºC), oxígeno disuelto (8,1±0,7 mg L -1 ), pH (7,3±0,2), amonio (0,004±0,003 mg L -1 ), nitrito (0,52±0,2 mg L -1 ) y nitrato (3,45±2,6 mg L -1 ). Se dio inicio a la alimentación el día 15 post-captura, utilizando alimento vivo (Odonthestes regia regia, Mugil cephalus), crustáceos (Emerita analoga), alimento fresco (Engraulis ringens y Dosidicus gigas) y artificial semihúmedo. Durante los primeros días de acondicionamiento los peces mostraron una disminución en el peso, hasta su adaptación a las condiciones de cultivo, luego de lo cual se produjo un incremento continuo en ambos sexos. La tasa específica de crecimiento fue positiva a partir del tercer mes y la tasa de crecimiento relativo mostró que en agosto 2010, el peso promedio se incrementó 24,5% en machos y 16,2% en hembras. Se realizó un análisis patológico a los ejemplares capturados y se observó la presencia de diferentes parásitos internos y externos, entre ellos predominaron Entobdella sp. y Philometra sp.
