The importance of the fishing industry.
It was one of the first ways that man obtained food.
From ancient times, fish were one of the most highly appreciated merchandises.
The most important fishing items are hooks and nets.
Trawling, normally carried out near coasts and deep-sea fishing..
Ships use modern echo-sounders and radars to locate shoals of fish.
Contamination and over fishing have stricken marine biodiversity deadly wounds. The damage may well be irreparable, but we are still in time to take urgent and effective steps on an international scale to stop life from disappearing completely from our oceans and seas.

- Seas and oceans are important sources of food.
Every year, some 130 million tones of fish are caught the world wide.
Fishing and fish farming industries employ 150 million people.

1’22’’ HISTORY
Though both arrows and spears were first used for fishing, later on hooks were used too.
Fishing and sailing have always gone hand-in-hand
One of the civilisations with a more pronounced fishing tradition was the Phoenicians.
They traded fish throughout the Mediterranean.

Fishing can be split into two different types: trawling and beam trawling
Trawling takes place near coasts and in beam trawling, trawlers can stay at sea for months at a time.
Cold seas generally contain more fish than warmer waters, because they contain more oxygen.
Equipment can basically be split up into nets and tackle.
Hooks, harpoons and long lines can all be classified as tackle.
Nets are the most important items of fishing tackle.
There exist fixed nets, encircling nets and beam nets. These are towed by ships across sea beds.
Beam nets are particularly aggressive because they are not selective.

Raising fish in captivity is called “Farming Fish” or “Aquiculture”. They are fish farms. They have been used throughout history.
Nowadays, fish farms are normally either artificial ponds or netted or enclosed areas of sea.
Aquiculture is the great future hope for mitigating those acute problems produced by over fishing seas and oceans.

Oceans and seas covering 2/3 of our planet’s surface hold 90% of the world’s living biomasses. 13 of the 17 largest shoals of fish in the world had either been depleted or in acute recession.
Captures exceed established limits and fish that are too young are being caught. This is why fish do not replace themselves.
Over fishing and pollution have caused debasement to seas. We are exterminating the life in our seas and oceans.
If we do not act soon, we will destroy one of the most important sources of life and food on our planet
