Studies under (a) should particularly in- clude improvement of existing and develop- ment of new methods to establish stock identity and to estimate abundance, trends, population structure and dynamics, and mi- grations. Studies under (b) should focus on locating areas of special importance to breed- ing and feeding. Studies under (c) should include research on habitat requirements, feeding ecology, trophic relationships, dis- persal, and sensory biology with special regard sisältää elinympäristöä koskevien vaatimus- ten, ravintoekologian, ravintoketjujen, leviä- misen ja aistien biologian tutkimusta, kiinnit- täen erityisesti huomiota saasteiden vaikutuk- siin sekä kalastuksen häiriöihin ja vuorovai- kutuksiin, mukaan luettuna menetelmien ke- hittäminen kalastuksen vaikutusten vähentä- miseksi. Tutkimusta ei tulisi tehdä tappamalla eläimiä, ja tutkimustarkoitusta varten vangitut eläimet tulisi vapauttaa terveinä.
