Chapter 1 Flashcards
Is a form of agriculture that involves the propagation, cultivation, and marketing of aquatic animals, and plants in controlled environment.
AQUACULTURE
When does the world fish farming first practiced in china?
2000 B. C.
When does the pioneers began to supply brood fish, fingerlings and lessons in fish husbandry to would be Aquacultirists
19th Century
When does commercial fish culture in the United States was mainly restricted to rainbow trout, bait fish, and a few warmwater species, such as the buffaloes, bass, and crappies.
1960’s
When does firmly established catfish industry, which originated in the southeastern United States
1950’s
When does firmly established catfish industry, which originated in the southeastern United States
1950’s
Was characterized by rapid expansion and relatively high production costs that resulted in low yields and inefficiency
1st phase or pioneering phase (1960-1970)
Gave rise to major improvements in production and lower unit costs. In this phase there is a drastic shakeout of unprofitable and marginal producers when feed costs rose as a result of a scarcity of fish meal.
2nd phase (1971-1976)
Saw vastly improved productivity greatly increased acreage, and lower production costs.
3rd phase (1977-1982)
Saw a decreased rate of expansion in the catfish industry, while production of other aquaculture products such as salmon, stripped bass, crawfish, and tilapia increased.
4th phase (1982-1989)
Enumerate the negative impact of wild caught fish
-Environmental Issues
-Destruction of habitat
-Muroami
-By-catch
-Overfishing
-Orange Roughly
-Bottom Trawling
In 2015 of Sea food Production How much does the production of Aquaculture?
106.00 million tons
In 2015 of Sea food Production How much does the production of Capture Fisheries?
93.74 million tons
CLASSIFICATION OF AQUACULTURE
-with low production per unit volume?
EXTENSIVE AQUACULTURE
Production per unit volume is much higher and more technology and artificial inputs must be used to achieve this.
INTENSIVE AQUACULTURE
