However, due to extensive exploitation in the last century, the numerous wild stocks are at historically low levels, the species itself being classified as vulnerable to extinction. In the past decade, the farming of cod has become a commercially viable practice, however there remains a number of critical production bottlenecks, a prominent one being that stocks reach sexual matu rity during the production cycle. During this physiologically demanding process, maturing fish stop growing and channel nutrients into gonadal rather than somatic growth, thereby extending the production cycle. Such problems have been traditionally addres sed in other species such as Atlantic salmon through the use of artificial photoperiod manipulation. However recent similar work in Atlantic cod suggests that it has a heightened sensitivity to light and therefore, at present, no suitable lighting system is available to the industry that can reproducibly regulate stock performance in commercial on-growing systems. Furthermore, lighting management is an intrinsic component in successful larvae and juvenile production, with the potential to impact feeding, growth and survival. However modern production practices has not exploited this technology optimally due to lack of adequate scientific back-up as well as the availability of specialized lighting systems. This project aims to design, develop and validate novel efficacious photoperiod management systems, which can radically improve cod farming productivity. To this end, this proposal will bring together an international network of academic institutions, as well as an array of commercial aquaculture producers both in Norway and UK to help the project initiator (Intravision Aqua) achieve this goal.
Goals:
(1) Develop know how on cods perception to light; (2) Develop sexual maturation kit to detect sexual maturation; (3) Develop and test underwater light systems able to suppress sexual maturation in cod in fish farming.
