AquaExcel at NTNU


CodTech

The new facilities of Centre of Fisheries and Aquaculture at NTNU were established in 2007 in order to stimulate interdisciplinary research and education in the fields of aquaculture and fisheries. The Centre is located at Sealab, which houses laboratories for the cultivation of both marine and freshwater organisms under controlled conditions.

The automated start-feeding CodTech rig consists of 16 tanks of 160 l each. It is especially designed for controlled experiments with marine pelagic fish larvae. Continuous in-house cultures of live prey organisms (rotifers, Artemia, copepods) and microalgae provide a good basis for nutritional and developmental studies of marine fish during larval and fingerling life stages.

The experimental facility is equipped with automatically controlled feeding, water exchange and online measurements of live feed density. Environmental variables, such as temperature, light, dissolved oxygen, carbon dioxide, and nutrient concentration are also monitored and controlled electronically. This can guarantee optimal cultivation conditions on a continuous basis. Incoming water undergoes a microbial maturation process whereas effluents are submitted to an advanced disinfection procedure. The latter makes the facilities particularly attractive for experiments with different bacterial communities and possible contaminants. All tanks have underwater cameras for remote observation. This combination makes the facility one of the most advanced cultivation hatchery units in Europe.
