Of course, the climate change impacts fishery in bad way. I think fish breeding is one of the solution (we can master almost all of the ecological parameters)
Climate change affects the environment and aquaculture in short term as it may be responsible for losses of production and infrastructure created by risky events such as floods, amplified risks of diseases, parasites and harmful algal blooms. Long-term impacts can include reduced availability of wild seed as well as reduced precipitation leading to increasing competition for freshwater. And for avoiding all these events i am agree with Rasoloariniaina Jean Robertin.
A study conducted by the Institute for Environment and Development (IIED) shows that climate change threatens fishing activities in Africa. Increased temperatures and sea-level rise, associated with ocean acidification, could reduce fish stocks, destroy habitats and affect the migrations of different species of fish.
Jean-Pierre Quignard, professor in Ichtyology, tells about what solutions can we find to the modifications brought about by climate change in the Mediterranean: I am a researcher, I study fish and in this field, I see no solution.
Indeed, in the Mediterranean, there are new species arriving that completly modify the equilibrium that change the relations in the trophic chain in the trophic network of Mediterranean species. Thus, some species are going to dominate, others will be eliminated by pure competition
In their study entitled «Ichthyofauna of the Languedoc coast, Gulf of Lion: faunistic and demographic modifications» (Vie et Milieu 43(4):191-195 ; January 1993), Quignard Jean-pierre and A. Raibaut report the capture for the first time of six species of fishes in the Gulf of Lion which is getting warmer so much so that this area can welcome species coming from tropical and subtropical areas, from the Atlantic or the Indo-Pacific region. The authors confirm the presence of three other species. It is shown that subtropical species are increasing in abundance whereas those of boreal origin are decreasing.
Yes of course rising ocean temperatures and ocean acidification are radically altering aquatic ecosystems. Climate change is modifying fish distribution and the productivity of marine and freshwater species. This has impacts on the sustainability of fisheries and aquaculture. while changing rainfall patterns and water use impact on inland (freshwater) fisheries and aquaculture. Many studies show that climate change threatens the fish migration and productivity of fishes.
Yes, there are evidence that climate change may be impacting fisheries industry badly in some cases, and particularly to industries around the Peru coast. Because there is an indication that due to greenhouse warming there is an increasing tendency in the extreme El Nino events. Therefore, with changing climate well known fisheries industry will be largely impacted in the region.
Note, good fishing grounds typically are found where upwelling is there and it other way around for downwelling. Please note, climate change does impact upwelling and downwelling process. So the fisheries
