Terminology


Capture fishing
Capture fishing is the largest extractive use of wildlife in the world, and one of the largest uses of an ecosystem “good.” It is a critical source of protein and livelihood, employing over 40 million fishers in Africa alone, and representing more than 20 percent of the animal protein in the diet of 2.6 billion people. In developing countries, where the vast majority of fishing communities and fishers are located, fishing is uniquely important to livelihoods, food security, and poverty alleviation.

Polyculture
This is an practice where more than one species of aquatic organisms are cultured in the same pond, in order to effectively utilize the full ecological niches of the pond ecosystem.

Marine aquaculture
This refers to culturing species that live in the ocean. Species include oysters, clams, mussels, shrimp, and salmon.

Freshwater aquaculture
This refers to culturing species that are native to rivers, lakes, and streams. Species include trout, catfish, tilapia, and bass.
