The commercial feasibility of rearing pompano, Trachinotus 

 carolinus (Linnaeus) , in cages. 



Univ. Miami Sea Grant Progr., Tech. Bull. No. 26, 62 pp. 

 Pompano are believed to be suitable for aquaculture, but success 

 has been limited. This study was conceived to rear pompano in 

 cages at five stocking densities. Estimates are made of costs 

 (for cages, labor, feed and fingerlings, but not for water column 

 leasing, on-shore installation, eguipment and supplies, and mar- 

 keting) and gross revenue. The estimates are based on the 

 researcher's study and other information. Present markets are 

 for a 1-pound fish, but an 8- to 10-ounce pan-sized fish may be 

 acceptable and would be advantageous, since growth seems to slow 

 once this weight is reached. Higher prices are assumed because 

 the quality of the cultured fish is thought to be superior to 

 wild fish. Factors relating to cost reduction are discussed: 

 stocking, wild-fish usage of food (from outside the cage), the 

 possibility of conditioning pompano for noncage culture, 

 fingerling cost, feed conversion rates, and other factors. 

 Subject descriptors: 



Pompano; biology; biological feasibility; experiment; economic 

 feasibility; markets; revenue; costs.

The white amur: a controversial biological control. 

 Amer. Fish Farmer World Aquacult. News 2(6) : 6-9. 



The article discusses mechanical and biological vegetation 

 control as alternatives to chemical controls. Mechanical ir.ethods 

 involve the physical removal of weeds from lake areas. These 

 methods are expensive, time-consuming, and inefficient. Two 

 possible methods of biological control are available, pathogenic 

 viruses and herbivorous fish. Viral methods are still in 

 experimental stages of development and at present are not 

 feasible. Among the herbivorous fish, the white amur 

 (Ctenopharyngodon idellus) seems most promising. Native to Asia, 

 it is a member of the Cyprinidae family, which includes carp and 

 minnow species. These fish grow at a rapid rate and may become 4 

 feet long and weigh up to 100 pounds over a period of several 

 years. They begin to feed on aquatic vegetation when about 1 

 inch long. The white amur eats as much as two to three times its 

 body weight per day. Also mentioned are the possibilities of 

 sport and commercial fishing, reproduction, possible adverse 

 effect on lake habitats, and control. 

 Subject descriptors: 

 White amur; biology; biological feasibility; problems; benefits.
