Improving data deficiencies in length‐weight relationships for fish species around an artificial breakwater and adjacent soft‐bottom at the central coast of Peru

Abstract

Long-term environmental monitoring studies includes morphometric data (length and weight) of aggregating fish species around this artificial structure and adjacent soft-bottom habitats. We used these data, obtained biannually (summer and spring) between 2012 and 2018, to estimate population parameters such as length-weight relationships (LWRs) for 28 species. Gender and ontogeny-based differences in LWR were determined in four species, while novel LWR information was generated for all other species.
