Balanced harvest : concept, policies, evidence, and management implications
Zhou, Shijie; Kolding, Jeppe; Garcia, Serge M.; Plank, Michael J.; Bundy, Alida; Charles, Anthony; Hansen, Cecilie; Heino, Mikko Petteri; Howell, Daniel; Jacobsen, Nis S.; Reid, David G.; Rice, Jake C.; van Zwieten, Paul A.M. (Peer reviewed; Journal article, 2019-06-11)Balanced harvest has been proposed to reduce fishing impact on ecosystems while simultaneously maintaining or even increasing fishery yield. The concept has attracted broad interest, but also received criticisms. In this ... -
Balanced harvest: Utopia, failure, or a functional strategy?
Kolding, Jeppe; Garcia, Serge M.; Zhou, Shijie; Heino, Mikko Petteri (Peer reviewed; Journal article, 2016-04-21)Since “balanced harvest” was proposed in 2010 as a possible tool in the operationalization of the ecosystem approach to fisheries (EAF), the concept gained extensive international attention. Because maintaining ecosystem ... -
Effects of ambient oxygen and size-selective mortality on maturation and growth in guppies
Diaz Pauli, Beatriz; Kolding, Jeppe; Jeyakanth, Geetha; Heino, Mikko Petteri (Peer reviewed; Journal article, 2017)Growth, onset of maturity and investment in reproduction are key traits for understanding variation in life-history strategies. Many environmental factors affect variation in these traits, but for fish, hypoxia and ... -

Fisheries in the Drylands of Sub-Saharan Africa – “Fish come with the rains”. Building resilience for fisheries-dependent livelihoods to enhance food security and nutrition in the drylands
Kolding, Jeppe; Zwieten, Paul A.M. van; Marttin, Felix; Poulain, Florence (FAO Fisheries and Aquaculture Circulars ; 1118, Book, 2016)Dryland areas cover more than half of sub-Saharan Africa and are home to nearly 50 percent of its populations, who depend on agriculture (including livestock, crops and fisheries) as their main livelihood strategy. Sporadic ... -
Fisheries, the inverted food pyramid
Kolding, Jeppe; Bundy, Alida; Zwieten, Paul A.M. van; Plank, Michael J.
