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 22 1. 500 B.C. – 500 A.D. is considered the ________ ________ of common carp culture. 2.
