FISHERY

Water surface area for aquaculture is the area used for
aquaculture, including the area of embankment; for aquaculture breeding
and hatchery area includes necessary supplement areas such as filtering

ponds and letting out ponds. This indicator does not cover areas of land
with special-use water surface for other purposes, but are used for
aquaculture such as irrigation and hydropower reservoirs.

Aquatic production refers to volume of an aquatic product or a
group of aquatic species obtained during a given period, including
aquatic capture production and aquaculture production:

 Aquatic capture production includes production of catches from
the sea, and production of naturally captured from rivers, streams, lakes,

lagoons, or rice fields, etc.

 Aquaculture production includes all aquaculture production
resulting from aquaculture.

Quantity and capacity of motorized marine vessels and boats is
the number of actual vessels, boats engaged in marine capture fisheries
during the year; including newly-built motorized boats and vessels for
purposes of long-term marine capture fisheries.

Capacity of vessels and boats is the total available capacity of the
main engines of vessels and boats at a given time. Unit of capacity is
horsepower (CV). Motorized vessels and boats for marine capture

fisheries are divided into different groups: less than 20CV; from 20CV to
under 50CV; from 50CV to under 90CV; from 90CV to under 250CV;
from 250CV to under 400CV; from 400CV and over.
