Fisheries Flashcards
How much of of the world’s oceans are subject to industrial-scale harvest?
Kroodsma et al., 2018
More than half
Area 4 x terrestrial agriculture.
Mobility =…
McCauley et al., 2015
The high mobility of many marine animals offers some increased, though limited, capacity for marine species to respond to climate stress, but it also exposes many species to increased risk from other stressors.
Can’t keep up…!
Pauly and Zeller, 2016
In many developing countries (and likely also in many ‘transition‘ countries), fish is the major animal protein source that rural people can access or afford; and they are also an important source of micronutrients essential to people with otherwise deficient nutrition.
Growing popularity in developed/ rapidly developing economies creates a demand that cannot be met by fish stocks in their own waters
What’s most at risk
Pinsky et al, 2011
Understanding which species are most vulnerable to human impacts is a prerequisite for designing effective conservation strategies.
Large-bodied species and top predators are the most at risk, and it is commonly assumed that such patterns also apply in the ocean.
Organisms are expected to adapt or move in response to climate change, but observed distribution shifts span a wide range of directions and rates.
Pinsky et al, 2013
Climate velocity explained the magnitude and direction of shifts in latitude and depth much more effectively than did species characteristics.
Cod decline
Ames, 2004
In 1998, National Marine Fisheries service (NMFS) reported Atlantic cod stock sin the Gulf of Maine were over exploited and at extremely low biomass levels (Mayo et al. 1998)
