Abstract

Pacific white shrimp, Penaeus vannamei, was paired with blue tilapia, Sarotherodon aureus in three 42-day growth trials conducted in outdoor tanks, from May 23 to October 11, 1993.

Each tank had a surface area of 5m2 and water depth of 80 cm. Two tanks contained 100 shrimp (20/m2) in monoculture and 2 tanks contained 100 shrimp in polyculture with 3 tilapia (0.6/m2). All tanks were given the same amount of feed. Water quality was monitored throughout and no significant difference was found between the two treatments.

The tilapia did not significantly reduce the production of marine shrimp when the shrimp were stocked at a mean weight of 9.27 g (S.D. = 2.47). Although some decrease in shrimp growth was noted, the tilapia production made up this difference at no extra cost. Extrapolation of production results to one hectare showed production of 3,132 kglha of shrimp in monoculture, compared with 2,812 kglha of shrimp plus 473 kglha of tilapia in polyculture, for a combined total of 3,285 kg/ha.

It was also determined that tank culture of marine shrimp and tilapia, whether in monoculture or polyculture, may be practiced with good results in the emerging field of "backyard aquaculture."
