Which community indicators can measure the impact of fishing? A review and proposals (2003, background): “Before claiming that mean trophic level in the community might be a sensitive indicator of fishing effects (Pinnegar et al. 2002), the magnitude, causes, and consequences of this variability should be carefully examined and an appropriate methodology should be developed (for an appropriate model of ”
Size structural change in lightly exploited coral reef fish communities: Evidence for weak indirect effects (2004, background): “Fisheries exploitation can be highly size selective: larger-bodied individuals are preferred and the rate of removal of individuals may be greater from species that attain large body sizes (Pauly et al. 1998; Jennings et al. 1999a; Pinnegar et al. 2002).”
State of the World’s Fisheries (2003, background): “Nevertheless, other techniques have also demonstrated similar declines in the mean trophic level of fishery landings for specific regions such as the Gulf of Thailand (77), the Celtic Sea (78), and on both coasts of Canada (79).”
Stable isotope analysis as a tool for elasmobranch conservation research: a primer for non-specialists (2012, background): “2012), changes in assemblages over time (Pinnegar et al. 2002; Jennings et al. 2002) and with other environmental variables (Polunin et al.”
Does diet in Celtic Sea fishes reflect prey availability (2003, unknown): “Marked changes are known to have occurred in the Celtic Sea ecosystem in recent years (Pinnegar et al., 2002), and given such changes it might be expected that the diet of predatory species will have varied in response.”
Testing candidate indicators to support ecosystem-based management: the power of monitoring surveys to detect temporal trends in fish community metrics (2004, background): “and the surveys are conducted on more heterogeneous habitats (e.g. Celtic Sea survey; Pinnegar et al., 2002).”
Understanding fishing-induced extinctions in the Amazon (2015, background): “It has been argued also that the prices of some fishes are inversely proportional to their abundance (Pinnegar et al., 2002) such that the higher values of overexploited species can promote extinction (Dulvy et al., 2003).”
Stable isotope profiles of large marine predators: Viable indicators of trophic position, diet, and movement in sharks? (2011, methodology): “Size as a surrogate measure of TP has therefore been used as a tool to examine human-induced impacts on community structure (Pinnegar et al. 2002; Dulvy et al. 2004), alterations in trophic linkages (Pauly et al. 1998), and (or) cascading effects of predator removal (Myers et al. 2007).”
Isotopic niches and trophic levels of myctophid fishes and their predators in the Southern Ocean (2010, background): “The stable isotope method also allows quantifying trophic levels of consumers and thus comparing taxonomically related and unrelated species within a given ecosystem (Hobson et al. 1994; Pinnegar et al. 2002; Cherel et al. 2008).”
Foraging ecology of Mediterranean fin whales in a changing environment elucidated by satellite tracking and baleen plate stable isotopes (2011, background): “…western Mediterranean Sea and interpreted it as ‘fishing down the marine food web’, mostly through diversification and (or) substitution in the species being targeted (marketed), as might be ex - pected where the supply of the preferred target species has begun to dwindle (Pinnegar et al. 2002).”
Climate change impacts on the biophysics and economics of world fisheries (2011, background): “For example, in spite of the increased catches in the Celtic Sea, the total landed value decreased because a larger proportion of the catch consisted of smaller, lower-priced specie”
