Detailed explanation-2: -Fish is the world’s most highly traded food commodity. In addition to the roughly 100 million tonnes that are consumed for food each year, fish also provide fish oil, glue, animal feed, and fertilizer, and play a growing role in biomedical research.

Detailed explanation-3: -Fishery resources, unlike minerals and fossil fuels, are renewable in the sense that they are capable of growth. Unlike forests and most other renewable resources, fishery resources are difficult to manage effectively because they are, with few exceptions, a common property.

Detailed explanation-4: -Marine resources are physical and biological entities that are found in seas and oceans that are beneficial to man. They include fish, coral reefs and crabs, fungi, etc. A lot of conservation effort is required to protect these resources from human destruction activities like pollution and over fishing.

Detailed explanation-5: -Capture fisheries and aquaculture depend on the use of natural renewable resources and other resources (e.g. aquatic species, land and water) as raw material. Other resources such as hatchery-produced seeds, feeds and fertilizers are artificially generated.
