On acoustic identification, sizing and abundance estimation of fish
Midttun, Lars; Nakken, Odd (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1971)A method using the fish angle (i.e. the change in target strength with fish aspect) for identification purposes is described. Significant differences in fish angle between cod and coalfish have been observed at sea. The ... -
