Considerations

890.2 Least efficient (older model and specimen)
Clambunk most efficient (+ biomass)…..

…..but more complex organization

Limitations: no distance recorded….

….(but large #obs and generally even conditions)

Only small part of the data!

SLIDE 15

Conclusions

Lots of reliable information
Production monitoring data has specific use
Combine several streams for modelling
