Quality evaluation of wels catfish Silurus glanis from outdoor flow-through and indoor recycling aquaculture systems

Popis výsledku v původním jazyce

Wels (European) catfish, Silurus glanis L., is a high valued fish with a very long tradition in European pond aquaculture. Recently, the quality of its flesh, suitability of a very good growth performance in high stocking densities and ability to ingestartificial pelleted diets, led to its wider utilisation under conditions of intensive warm-water farming units including recycling systems. The evaluation of processing yields and fecundity of wels catfish was performed in October - December 2003 using fish cultured in two different farming units - (1) outdoor pond aquaculture system (PAS) with flow-through regime (24.6#0.2°C) and (2) the indoor tank aquaculture system (TAS) with recirculation regime (26.0#1.0°C). Despite no significant differences appeared in their processing traits, the condition coefficients (based on eviscerated body weight) were significantly higher in PAS fish. However these coefficients were almost identical when calculated from the total weight of fish. Visceral
