Fisheries that rely on short life species, such as shrimp or sardine, have been more affected by climate change, because this phenomenon affects chlorophyll production, which is vital for phytoplankton, the main food for both species.
Disclosed by the research “Socioeconomic Impact of the global change over the fishing resources of the Mexican Pacific” headed by Ernesto A. Chávez Ortiz, from the National Polytechnic Institute (IPN).
Work performed at the Interdisciplinary Center of Marine Sciences (CICIMAR) from the IPN, indicates that in the last five years there have been no “spectacular” changes attributable to climate change, what has affected the fishing resources more is the over demanding market.
“Globally, a great part of the fishing resources is being exploited to its maximum capacity, several have overpass its regeneration capacities and are overexploited” Chávez Ortiz points out.
The specialist at CICIMAR details that the research consisted in exploratory weather and fisheries analysis, and confirmed what has been intuitively said for a while: a lot of the variability in the fishing is due to climate change, the problem is that evidence hadn’t been found to prove it.
