THE Scottish Sea Angling Conservation Network (SSACN) has launched a new webpage which presents interactive length/weight curves for over 45 species of sea fish, in a move which allows anglers to quickly return their catch and work out the weight later.

According to Lewis Cowie, SSACN's Project Lead: "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 inaccuracies there may be will be the same for everyone.

"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’ on www.ssacn.org"

The length/weight curves are a part of SSACN’s Give Fish A Chance (GFAC) initiative, which reflects the fact that anglers, whilst enjoying their sport and occasionally taking a fish for the table, are keen to minimise their impact on the environment and on the fish themselves.

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.
