Overharvesting of Fish Population/Aquaculture Industry

Introduction:

Fishing is central to the livelihood and food security of 200 million people, especially in the developing world. One in five people on this planet depend on fish as their primary source of protein. The depletion of fisheries poses a major threat to the food supply of millions of people. The rapid growth in demand for fish and fish products is leading to fish prices increasing faster than prices of meat. In the last decade, in the north Atlantic region, commercial fish populations of cod, hake, haddock and flounder have fallen by as much as 95%. The dramatic increase of destructive fishing techniques worldwide destroys marine mammals and entire ecosystems.

 

Overharvesting

Overharvesting is defined as the excessive fishing of aquatic animals that include fish and shellfish. With the advancement of technology, it is easy to catch loads of fish in just minutes. This is one of the main causes for overharvesting.

 

Negative effects of overharvesting:

·         Leads to the extinction of wildlife

·         Over fishing also affects the structure of food webs and food chains

 

Positive effects of overharvesting:

• It keeps the price of fish way down.

• The capturing of fish has gotten easier of the years thanks to technology

                                        

SOLUTIONS TO OVERHARVESTING

·         REDUCTION OF BYCATCH

·         PROTECTION OF HABITAT

·         REGULATING FISHING WITH QUOTAS AND DATES

·         CONSUMER EDUCATION

·         AQUACULTURE

Aquaculture

According to UN agencies, aquaculture is growing more rapidly than all other animal food producing sectors. Aquaculture can be defined as the cultivation of the natural produce of the water (as fish or shellfish). Aquaculture is the agriculture of the oceans.

•Also known as “Aquafarming

•Farming of aquatic organisms

•Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions

•Can be contrasted with commercial fishing, which is the harvesting of wild fish
