Marine fish weight estimation

fishsmart150 transWe’ve added new functions to allow anglers to estimate the weight of a sea fish by simply measuring its length.

A new web page has been added to the site  which presents interactive length / weight curves for over 45 species of sea fish. The curves are an integral part of the Give Fish A Chance initiative which reflects the fact that anglers, whilst enjoying their sport and occasionally taking a fish for the table, are keen to do what they can to ensure the minimal impact to the environment and to the fish themselves.

Responsible anglers have always recognised that they should do everything in their power to return any fish not wanted for the table back to the water as fast as possible but most also like to have a idea of the weight of a good fish.

Estimating weight by measuring length allows anglers to quickly return their catch and ‘weigh’ it later.

At the launch, Lewis Cowie our Project Lead commented : “Although there is no doubt that fish can have different weights for the same length dependent on several factors – whether they are gravid, post spawning, sick or healthy, have good access to food-stocks etc.- weight estimation based on a fish’s length offers a credible solution; unlike the appliances typically in use by anglers, any in-accuracies there may be will be the same for everyone.

and continued “If anyone has any historic accurate records of weight / length for any species, they could be very useful in helping refine our models and we would be very grateful for any input; please get in touch via the ‘Contact Us’ facility.”

GFAC also consists of a series of advisory notes and voluntary measures aimed at helping anglers to better understand the issues associated with catch and release, handling fish and doing what they can to help ensure ‘fish for the future’.
