Feed training of peacock bass (Cichla sp.).
The Amazonian cichlid peacock bass (Cichla sp.) is a highly marketable food and sport fish, therefore a suitable species for aquaculture. However, because of its piscivorous feeding preferences, the species does not accept dry feeds voluntarily, turning its intensive culture difficult and costly. This study aimed to wean fingerling peacock bass from inert moist food to dry diets. In a first exp...
متن کاملEvidence for a natural hybrid of peacock bass (Cichla monoculus vs Cichla temensis) based on esterase electrophoretic patterns.
Esterase (Est) and esterase-D (Est-D) electrophoretic patterns identified by starch gel electrophoresis of skeletal muscle protein extracts of 184 specimens of three species of peacock bass, locally known as tucunares (Cichla monoculus, C. temensis and Cichla sp), plus four specimens of a supposed hybrid (C. monoculus vs C. temensis), collected from the Central Amazon, were examined to determin...
متن کاملParasite fauna monitoring of matrinxã Brycon amazonicus (Spix and Agassiz, 1829) raised in aN intensive husbandry system in a stream channel in the state of Amazonas, Brazil.
The matrinxã, Brycon amazonicus, is one of the main species being used for aquaculture and fishery activities in the Amazonian region, yet little is known about the parasites that cause its diseases. The present study monitored parasite fauna infesting an intensive husbandry system in a stream channel. The collections were carried out monthly from September, 1997 to January, 1998. Water quality...
متن کاملYield and Biomass-per-recruit Analysis of Tiger Tooth Croaker (Otolithes ruber) in the Northwest of the Persian Gulf
Effects of age at first capture (tc) and fishing (F) as well as natural mortalities (M) on yield and biomass-per-recruit of tiger tooth croacker, Otolithes ruber were evaluated in the northwest of the Persian Gulf using the Beverton-Holt model. The yield-per-recruit (Y/R) was 175 (g/r), which was less than maximum yield-per-recruit value (217 (g/r)) at fishing mortality of 1 year-1. Current ...

Feeding of C/chla monoculu. Splx, 1829 (Teleo8tel: Clchlldae) during and after re..rvolr formation In the Tocantln. River, Central Brazil. We examined Cichla monoculus feeding In a stretch of the upper Tocantins River during construction of the Serra da Mesa power plant. Fishes were sampled bimonthly during two periods: reservoir filling (Dec/96 to Apr/98) and operation (Jun/98 to Feb/OO). Stom...
