Question

I have a question. I need this for my portfolio, please help me!

Answer 1

I am writing about how and when sardines were endangered including other details about sardines.

In one of my paragraphs, I am trying to prove that the fishes were endangered when advanced ships with advanced fish-hunting technology were developed, because that's when they started extincting.

My question, WHEN WAS THIS ADVANCED FISH HUNTING TECHNOLOGY DEVELOPED ?

Answer 6

Many of the most noticeable and important changes in the fishing industry have come in the past 150 years. The first modern improvement to the fishing fleet was mechanization. By the late 1800's sailing boats were being replaced by steamships. The era of the steamers, however, was short as they were quickly replaced by motor driven vessels early in the 20th century. The next major advance came in the 1940's when instrumentation was introduced into the fishing industry. During this time such technologies as echo sounder (to locate schools of fish) and later sonar, were introduced.

As the fishing industry grew and new larger and improved gear was added to the fisherman's arsenal, new fishing techniques were introduced. Also developed were new machines to manufacture the new fishing gear. One major advancement was mechanical net making which allowed larger nets to be created more efficiently. Over time the techniques and materials used to construct the nets improved. With mechanical net making the traditional netting fibers, hemp and linen were replaced with cotton and hard fibers. Later after World War II these were replaced with other synthetic, rot-proof materials.

Despite the much larger fishing equipment developed in the past several hundred years, mechanical tools such as the winch and pulley were not introduced into the fish industry until the beginning of the 20th century. During the 1950's mechanization of fishing equipment made several large advances. The invention of the power block to haul the gear significantly reduced the labor involved in preparing and moving equipment. Another important development was the invention of a power-driven drum to haul in and store large nets.

During the 1970's and 1980's fishing ships began to become more fully automated, with the trend towards full automation becoming common. On of the major technological advances that made this possible was the computer, which helped facilitate the complicated operations involved in fishing.
