Levante de Carpa Común (Cyprinus carpio) en Sistemas Cerrados de Recirculación, Bajo Condiciones de Laboratorio

Aquaculture is a major growth industry that is looking of more environmentally friendly production systems. Common carp production worldwide is mainly in China, which has allowed it to be the kind of major crop. Therefore evaluate systems where water is better utilized it is of great importance. The evaluation of C. carpius growth, survival and productive parameters in recirculating aquaculture system (RAS) was made. It takes 12 weeks for carried out two culture experiments. The experiment used 5 RAS each one with 100 fry. Body weight, standard length and total length were evaluated, and productive parameters were calculated. Control and supervision of physicochemical parameters were made. M1 fishes attained mean body weigth of 6.13 ± 0.80 g, standard length of 5.66 ± 0.24 cm and total length of 7.08 ± 0.23 cm, while in M2 these figures were 10.22 ± 0.89 g, 6.62 ± 0.18 cm and 8.2 ± 0.22 cm, respectively. Better growth in M2 was related with physicochemical parameters level within the range reported for this species. Weight and length growth did adjust to an exponential model in M1 and M2. In conclusion, initiation of common carp fry in RAS of low technology, did allows for good growth and survival, with low water use, and under highly controled conditions.
