“…Intestinal constriction was not seen in Hamun mahi until 21 DAH, and no histological differences between the anterior and posterior regions were observed. By contrast, in some species the intestinal constriction is evident at the early stages of the life history, such as in haddock (Hamlin et al 2000) and pike perch (Ostaszewska 2005) at 2 DAH, and in California halibut (Gisbert et al 2004), the common dentex (Santamaria et al 2004), Gilthead (Elba et al 2004) and Schophthlmus rhombus (Hachero-Cruzado et al 2009) all at 3-4 DAH. Due to the high mortality rate of Hamun mahi larvae during this period, they were transferred to the pond by the hatchery and, therefore, regular sampling was not possible from this stage onward.…”

“…Similar to most teleost fish species, S. zarudnyi hatchlings possess an undifferentiated, rudimentary digestive system (Hamlin et al 2000;Gisbert et al 2004;Chen et al 2006;Micale et al 2006;Zaiss et al 2006;Sanchez-Amaya et al 2007). Regional differentiation was established at the beginning of Stage 2 (Ostaszewska 2005) (11.25 ± 0.86 mm TL) and coincided with the time when the mouth opened at 3 DAH before exogenous feeding.…”

“…At hatching, Hamun mahi possessed a primordial liver and pancreas similar to those in halibut (Gisbert et al 2004), haddock (Hamlin et al 2000), and yellowtail kingfish (Chen et al 2006). The time at which accessory glands appear in fish varies between 2-3 DAH in Gilthead (Elba et al 2004), the common dentex (Santamaria et al 2004) and the common pandora (Micale et al 2006), due to their crucial role in metabolism at mixfeeding (intracellular digestion).…”

“…High mortality rates are mainly due to inadequate food composition and undeveloped digestive tract of larvae (Govoni et al 1986;Zaiss et al 2006). Therefore, knowledge of digestive tract developmental changes associated with food assimilation processes is essential for understanding nutritional physiology and can help identify limiting factors during larval rearing (Gisbert et al 2004;Mai et al 2005;Zaiss et al 2006;Sanchez-Amaya et al 2007). Although the basic mechanisms of larval development do not differ greatly among teleosts, there are considerable differences regarding the timing of ontogenic events.…”

The development of digestive tract and accessory glands in Hamun mahi (Schizothorax zarudnyi, Family: Cyprinidae) from hatching to 21 days after hatching (DAH) is described in this study. This information is critical for evaluating the digestive tract functional capacity and physiology of digestion in larvae, and designing optimal rearing techniques and artificial diets for this commercially valuable species. Based upon its feeding mode and structural changes in the digestive tract, larval ontogeny in S. zarudnyi was divided into three stages, Stage 1: 0-2 DAH, Stage 2: 3-8 DAH and Stage 3: from 9 DAH onwards. As in most teleosts, Hamun mahi at hatching had an undifferentiated digestive tract. The most critical ontogenetic events occurred at Stage 2. At the beginning of Stage 2, mouth opened in conjunction with the differentiation of the digestive tract. During Stages 2 and 3 the gut differentiated, and buccopharyngeal cavity, oesophgus and incipient intestine became distinguishable. At this stage digestive tract processes continued to develop (e.g. entrocyte's brushborders, appearance of digestive mucous cells at 4 DAH, and gut mucosal folds). The first taste buds and pharyngeal teeth appeared at the beginning of Stage 2. Histological observations suggest that digestive tract development of the Hamun mahi larvae, involving the presence of functional liver (vacuolated hepatocyes), exocrine and endocrine pancreas, and gallbladder enabled early larvae (from 3 DAH) to ingest, digest and assimilate the first exogenous food, even before endogenous reserves were completely resorbed. From Stage 3 onwards, most organs essentially exhibited an increase in tissue structure, size and number.

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.
