Parasitism, condition and reproduction of the European hake (Merluccius merluccius) in the northwestern Mediterranean Sea

It is well known that parameters relating to physical condition and reproduction of fish provide essential data for estimating the productivity of exploited populations, as is the case with the European hake (Merluccius merluccius) in the northwestern Mediterranean Sea. Although parasitism might aff...
