    Nyckelord :Northern shrimp; Pandalus borealis; shrimp pot; fishing; bycatch; gadoid; attract; green light; white light; UV light; LED light; underwater camera; video recording; behviour;

    Sammanfattning : In search of a less destructive alternative to current shrimp fishing methods, both in terms of bycatch reduction and increasing shrimp-catch in pots, this study aims to analyse the catches and bycatches of different pot designs and alternative attractants for pot fishing on Northern shrimps (Pandalus bore-alis). There are three main objectives: (1. LÄS MER

  5. 4. Black coffee twig borer, Xylosandrus compactus (Eichhoff) on robusta coffee in Uganda : impact of shade level on abundance of BCTB and knowledge levels about BCTB

  7. 5. Olfactory response in caterpillars of Pieris rapae for host recognition

    Kandidat-uppsats, SLU/Dept. of Ecology
