Description
The present study reports the first reference on length-weight relationships (LWR) and sexual dimorphism for Bassanago albecens, caught as bycatch in the commercial fishery in the Argentine continental shelf. A total of 91 conger eels were examined. Female specimens (ranged from 371 to 661 mm total length—TL) have body length larger than males (from 396 to 537 mm TL), but the length-weight relationships allometry coefficient was 3.76 for both sexes. Three out of seven morphometric measurements differed between sexes, in particular head size characteristics. These biometric data and their relationships are relevant to the management and conservation of fish diversity and fisheries.
