| 520 | |aPeak inseason echosounded biomass, estimated from colour echograms, was tested as a measure of prefishery biomass. Prefishery biomass was estimated as the sum of catch, as determined from sales slips, and spawner biomass, as estimated by the escapement stock assessment model. Results of simple linear regression analyses showed there was no relationship between echosounded and prefishery biomass estimates. Therefore, the current inseason echosounding methodology does not provide any basis for modifying the fishing quota as determined using the current stock assessment methodology. |
