The devastation of the fish stocks all began following the world wars, prior to that alot of fishing was done by sail boat which were not very productive in comparison, also during the war alot of boats could not fish at all as it was very dangerous i.e mines, gun ships, subs etc. after the war seen the introduction many diesel powered fishing vessels more efficient fishing machines. if you look at fish landed during the time of sail power compared to motor power we just became too good at catching fish and the wars made technology better as there was a need to be better !.
So we began catching more fish not tightly controlled at first nor did anyone really know how much fish was out there and fish that are mature breeding stock and also juvenile fish (sizeable) were taken in record numbers.
So fewer breeding fish and also catching fish before they can breed means we are hitting the stock from both ends !!!.
Scientists say that Commerical Fisherman provided them with info so they can base the quotas on, by the amount of fish landed in the previous fishing year, but still this isnt an effective way to control fish caught as this will only control fishing landed and over fishing goes on and the fish are bumped at sea, to feed the crabs, seals and bird life.
Am not saying we need a war to stop the fishing !!!, but sorry to say a total commerial Band is nessasary if fishing is going to be commerically viable in future and fish there for us as anglers.
We as anglers have no significant impact on fish stocks, percentage wise i would dare to say we catch less than 1% of the commerial fish caught, should the fishing become fantastic again we as anglers cannot catch as much as we want tho, a bag limit would need to be imposed on fish caught, as i would hate to see people going fishing on piers and it being like mackrel season 24/7 but with COD in the winter !!!.
Question is how many fish do we think is a reasonable amount to take home ? as many as you can catch ?.
