Well did you know in "sustainable fishing methods" in the text on page 96 it says"dredging causes significant habitat damage".
Mark Kurlansky in World With Out Fish said"NEVER EAT ANY KIND OF SHARK they produce few offsprings and mature very slowly which makes them unable to survive commercial fishing".
In research articles and glossaries it says" Overfishing occurs when fish and other marine species are caught faster than they can reproduce."
one way to buy fish that have been caught using sustainable fishing method "is to look for the marine stewards councils logo that tells you its been farmed not hunted" this is from the video how to buy sustainable seafood
Mark Kurlansky in World With Out Fish says in the case study of the bluefin tuna"NEVER EAT BLUEFIN TUNA this is a highly migratory fish and requires a great deal of international cooperation to regulate it is not well managed and is on the verge of being fished into extinction".
But there is a solution in the article "sustainable fishing methods" it says"harpooning is catching larger fish such as swordfish with hand hand thrown harpoons (just like in the whaling days) or with barbs fired from a gun.By-catch is almost nonexistent, since the fisherman are aiming at individual targets".
