Description

A chunky, predatory fish with a huge mouth and a grumpy expression, the stone bass or wreckfish is a huge deep sea fish which is occasionally landed by Cornish fishermen.


Sustainability Overview

This is a highly valuable, slow growing species that is vulnerable to over fishing and is classed as near threatened by ICUN. Catches to Cornish ports are low and sporadic but there is no management for this species and a lack of data making it hard to say that this species is sustainable.  They are caught using baited hooks – longlines or hand lines and juveniles  can be found beneath floating debris out in the open sea so is usually caught as a bonus when deep sea netters and potters chance upon them.

Wreckfish

Biology

This is a long lived, large mouthed, predatory species growing up to a maximum size of 2.1 meters in length and is very slow growing. They do not reach maturity until they are 90 cm in length which takes many years.  It has a high vulnerability to fishing (72% fishbase) 
Since the species lives deep and offshore, there may well be stocks of wreckfish that have been little reported or yet to be discovered. The real possibility of unknown stocks of unknown size makes it very difficult to estimate stock levels.
