Transcript The History of Aquaculture - Montgomery County Schools

1
1. To describe aquaculture and
understand its importance.
2. To examine the history of
aquaculture and observe its
present state.
3. To contrast aquaculture and
fishing.
2
• Is the act of raising and
harvesting fresh- and saltwater
plants and animals
• Incorporates raising fish and
shellfish under controlled
conditions for distribution and
consumption
• Includes raising tropical fish for
aquariums
3
• Was when aquaculture emerged in
China
– noticed fish were often washed into
ponds by monsoon floods
– inspired idea of “stocking” ponds to
provide families with food
– rice growers also noticed fish in the
rice fields and began practicing
polyculture
Polyculture – the raising of more than one species of
plant or animal at the same time in the same place 4
• Was the year when Fan Lai wrote “The
Classic of Fish Culture”
– earliest detailed study of fish culture
– describes the structure and function of
ponds which house and promote
propagation of carp
Propagate – to cause an organism to multiply
by any process of natural reproduction
5
• Is considered the “Golden Age” of common
carp culture
– Chinese continued to cultivate carp and
spread the practice to neighboring
countries
– achieved progress in techniques of
culture as well as recorded culture
systems
• Is the time in which southern Asia began
describing the use of reservoirs to hold fish
6
• Accounts for the rule of the Tang Dynasty in
China, which prohibited the cultivation of
carp
– found other species of fish to culture for
their food and overall livelihood
– discovered polyculture of fish in the same
pond compliment each other by eating
different types of food and staying in
different areas
7
• Is the period when fry collection and
dispersal in natural waters became highly
developed
• Was the era in India in which Namasollasa
presented a publication concerning the
fattening of fish in reservoirs
• Is the time in which Chow Mit publishes
“Kwei Sin Chek Shik” which describes fish
transportation in bamboo baskets
Fry – the young of fish
8
• Is when works concerning the
complete aquaculture process were
described, including the following:
– methods of raising fry to adults
– structure of ponds
– application of food
– disease control
9
• Is the first time brakish water
aquaculture was used in Indonesia
• Is the period in which the “Complete
Book of Agriculture” was published in
China, including information on pond
cultivation
Brakish Water – water which is saltier than
fresh water but not as salty as seawater
10
• Is the period in which communication
became readily available, allowing for the
spread of information among countries
• Allowed further fish culture methods to be
developed, including the following:
– fry production
– seasonal occurrences of fry
– transportation of fry
11
• Consisted primarily of fish culture
• Includes Cornell University offering a
curriculum for aquaculture in 1812
• Involves the transplantation and propagation
of fish from their natural environments to new
ones
– allowed Americans to continue to
purchase fish they were accustomed to
overseas
12
• Included identifying and
treating many diseases and
fungi present among fish
and their living environment
• Consisted of standardizing
common names of fish
• Consisted of finding
improved ways to transport
fish and fry
13
• Universities began to develop
aquaculture courses
• Public interest in fishing rose, leading to
the production of the baitfish industry
• New methods for fish transport were
utilized, including the airplane
14
• The Warmwater Training School at the
National Fish Hatchery was established in
Marion, Alabama
– provides training for federal hatchery
managers
• Feed costs were reduced after the first
dependable dry pellet diet for trout was
marketed
• An estimated 1.6 million ponds existed in the
United States by 1950
15
• The Peace Corps extended practicing
aquaculture in developing countries
• Research improved feeding practices,
disease control and organism growth
– led to production on a larger scale and
industry expansion
• The Sea Grant College Program granted
federal funding to land grant colleges for
aquaculture research in 1966
16
• Increase in catfish pond acreage
from 400 in 1960 to 40,000 in 1970
• Research allowed for better farming
techniques after finding specific
traits can be improved in fish
– allowed for better growth,
feed conversion and
efficiency
• The Food and Agriculture Act of
1977 stated Congress designate
aquaculture as a basic duty of the
Department of Agriculture
17
• Aquatic bioengineering emerged
• The National Aquaculture Act of 1980
allowed for the establishment of the National
Aquaculture Development Plan
• Harvest limitations on commercial fishing
began being imposed
Bioengineering – the application of engineering
principles and techniques to problems in medicine and
18
biology
• Production doubles from 1984 – 1994
• Many fishermen move from traditional
fishing to aquaculture
• Perception of aquaculture changes as
more people see it as a branch of
agriculture
19
• Total value of world
aquaculture production in 2000
was reported as $56.5 billion
• Aquaculture production in
developing countries as well as
food-deficit countries has been
steadily growing since 1970
• Aquaculture production is
growing more rapidly than all
other food production
categories
20
• Aquaculture production in the
United States has continued
to increase since the 1970’s
• United States’ fish and
shellfish exports have more
than doubled since 1985
• United States’ total
consumption and importation
of fish and shellfish products
have gradually increased
21
• Differences include:
– aquaculture involves production and
growth while fishing only involves the
harvesting
– fish in aquaculture are kept in a controlled
environment while those caught in fishing
are from the wild
– cost efficiency as aquaculture yields a
higher income than fishing
