• Additional equipment (feeding, handling, and monitoring equipment)

Question 5

A form of aquaculture involving the farming of species of algae.

Answer 5

Algaculture

Question 6

The
majority of algae that are intentionally cultivated fall into the category of ____
(also referred to as phytoplankton, microphytes or planktonic algae)

Answer 6

Microalgae

Question 7

The practice of cultivating and harvesting
seaweed. In its simplest form farmers gather from natural beds, while at the other
extreme farmers fully control the crop’s life cycle

Answer 7

Seaweed farming or kelp farming

Question 8

Aquatic Plants

Answer 8

• Algaculture
• Seaweed farming and Kelp farming

Question 9

The most
common form of aquaculture.
It
involves the breeding, rearing, and
harvesting fish in tanks, ponds, or
pens/cages. The fish raised in this are used for food and derivative products.

Answer 9

Fish farming or pisciculture

Question 10

A facility that
releases juvenile fish into the wild for
recreational fishing and to sustain a
species is known as a

Answer 10

Fish Hatchery

Question 11

An animal with a hard shell and several pairs of legs, which usually
lives in water. Crabs, lobsters, crayfish (Astaciculture) and shrimps are some examples.

Answer 11

Crustaceans

Question 12

Aquacultured shellfish include various oysters, mussels, and clam species. These
bivalves are filter and deposit feeders, which rely on ambient primary production
rather than fish or other feed inputs. As such, shellfish aquaculture is generally
perceived as benign or even beneficial.

Answer 12

Molluscs

Question 13

The
aquaculture practice of cultivating
sea urchins, primarily for their edible
roe, known as “uni” which is
considered a delicacy in many
cuisines, especially in Japan. This
farming
is
typically
done
in
controlled
marine
environments
where conditions such as water
quality
and
temperature
are
carefully managed to optimize
growth and roe production

Answer 13

Sea
Urchin
Farming

Question 14

It refers to the
systematic raising of jellyfish for food, feed, and cosmetics. It is a
type
of
emerging
aquaculture
technology that is at its early stages.
Some examples of cultured jellyfish
species include the Edible Jellyfish
(Rhopilema esculentum) cultured
primarily for food and the Nomura’s Jellyfish which is farmed for both
food and cosmetics.

Answer 14

Jellyfish Farming

Question 15

Echinoderms

Answer 15

• Jellyfish Farming
• Sea Urchin Farming

Question 16

Refers to
raising and breeding aquatic animals (fish, shrimp, crab,
shellfish, etc.) and plants for economic purposes by the use of
ponds, reservoirs, lakes, rivers,
and other inland waterways
(including brackish water), which
play an important role in the
aquaculture industry

Answer 16

Freshwater aquaculture

Question 17

Also
known as coastal aquaculture, is
a rapidly expanding farming
activity and plays an important
role in the overall fisheries
development effort. Marine and
estuarine shrimp, fish and crabs
are the farm products.

Answer 17

Brackishwater aquaculture

Question 18

Has been defined as
the cultivation, management, and
harvesting of marine organisms
in their natural environment
(including estuarine, brackish,
coastal, and offshore waters) or
in enclosures such as pens,
tanks, or channels.

Answer 18

Marine Aquaculture or Mariculture

Question 19

Refers
to
aquaculture production systems with low
production per unit volume

Answer 19

Extensive
aquaculture

Question 20

Characteristics of Extensive Aquaculture

Answer 20

• Low stocking density
• Natural feeds only
• Minimal human and technological
  intervention
• Minimal input

Question 21

System that produce
an
adequate
volume
of aquaculture produce relative to the
resources used.

Answer 21

Semi-intensive
aquaculture

Question 22

Characteristics of Semi-Intensive Aquaculture

Answer 22

• Moderate stocking density
• Natural feeds with supplemental feed
• Regular human and technological
  intervention
• Moderate water-change rate

Question 23

A system that is
characterized by an extremely efficient
use
of
resources
by
maximizing
production volume.

Answer 23

Intensive aquaculture

Question 24

Characteristics of Intensive Aquaculture

Answer 24

• High stocking density
• Regular feeding
• High
  human
  and
  technological
  intervention
• Use of Pumps and Aerators

Question 26

From “fry” to larger juveniles (often called fingerlings).

Answer 26

Nursery

Question 27

From juveniles to preferred market sizes

Answer 27

Question 28

Normally utilize much
more technical equipment than sea cage
farms, especially intensive production farms
with a number of tanks.

Answer 28

Land-based farms

Question 29

Primary Component of Land-based Farms

Answer 29

(1) Water inlet and transfer
(2) Water
treatment facilities
(3) Production units
(4)
Feeding equipment
(5) Equipment for
internal fish transport and size grading
(6)
Equipment for transport of fish from the farm
(7) Equipment for waste and wastewater
treatment
(8) Instrumentation and Monitoring
Systems.

Question 30

Normally it can be run with
rather less equipment than land-based
farms, the major reason being that water
transfer and water treatment (which is not
possible) are not necessary because the
water current ensures water supply and
exchange.
