Abstract
This study was conducted on the length-weight relationship of the smoothmouth marine catfish, Carlarius heudelotii, caught from the Gulf of Guinea by artisanal fishermen and landed at the Ukpenekang fish-landing site near Ibeno, Akwa Ibom State, Nigeria. The ‘r’ value for the 233 specimens of C. heudelotii sampled during the three months study period (April-June 2009) was 0.97. No significant difference in ‘R2’ (P>0.05) was noticed in the analysis of covariance between the fishes of different sizeclasses and sampling dates. The equation for length-weight relationship was W=1.02L2·4 for the overall sample. The overall condition factor was 1.29 (greater than one).

Genetic basis of resistance to stress in fishes. Molecular and classical investigations in a few model organisms
The paper focuses on the recent scientific results from genetics of thermal stress tolerance and discusses about heat shock genes in several model fish organisms, such as: the guppy (Poecilia reticulata), the Antarctic f...
Attempts to increase the growth rhythm of juvenile Northern pike (Esox lucius, L.) by adding enzyme based ingredients into dry feed
Northern pike’s rearing in recirculation systems is limited because of increasing FCR together with size of fish. The reason is apparently connected to the disability of pike to secrete sufficient digestive enzymes to pr...
