Potential vectors and sources of this recent invader include: 1) discharged ballast water from its native range in Asia or other areas where it has become established; 2) transport of larvae from established non-native populations in the Caribbean or South America via ocean currents; or 3) escape and subsequent migration from active aquaculture facilities in the western Atlantic.

A table of aggression intensity was Experience established, ranging from 1 (chasing) to 4 (intense combat). Crabs of intrafamily association performed more aggressive acts of shorter duration than interfamily, family B was more aggressive than those from families A and C: family C was the least aggressive, which is also the most morphologically distinct strain (a new strain with a red carapace). During the second fighting trail, the intensity and number of fights were significantly different to first fight conditions and also differed among families. Therefore, our results suggest that the aggressive behavior of Eriocheir sinensis is different among different families, and the combat experience has a significant effect on the secondary fight.

Their size, estuarine distribution, and diet preference for crustaceans and mollusks in their native range suggest that these shrimp may have significant impacts on a variety of species native to the northern Gulf of Mexico and Southeastern US. However, to date no studies have investigated this possibility. We examined tiger shrimp prey choice in mesocosm predation experiments. In these experiments, blue crabs and polychaetes exhibited the lowest survival rates (<25%) while small flat fish, grass shrimp, and juvenile penaeid shrimp exhibited the highest survival (>60%). In separate video observations tiger shrimp searched for prey by probing the sediment; consequently, juvenile blue crabs Callinectes sapidus Rathbun, 1896 that were buried were easily located and consumed.

  • Lobster Aquaculture Development in Vietnam and Indonesia 12
    Lobster Aquaculture Development in Vietnam and Indonesia 12 Clive M. Jones, Tuan Le Anh, and Bayu Priyambodo Abstract Development of spiny (rock) lobster aquaculture is of special interest because mar- ket demand continues to increase while capture fisheries production remains static and with little likelihood of any increase. This chapter provides a synopsis of infor- mation about the history, development, status and future of tropical spiny lobster aquaculture with a particular focus on Vietnam and Indonesia, where considerable development has already occurred. Vietnam is the only country in the world where farming of lobsters is fully developed and commercially successful. The Vietnamese industry is based on a natural supply of seed lobsters – the puerulus stage, as hatch- ery supply is not yet available due to the difficult technical demands of rearing spiny lobster larvae in captivity. Vietnam currently produces around 1600 tonnes of premium grade lobsters, primarily of the species Panulirus ornatus, that are exported to China where the price is higher. The industry is valued at over $US120 million. This success led to significant interest in Indonesia where a fish- ery for seed lobsters has become well developed, with a catch 10–20 times greater than that of Vietnam. However, growout of lobster in Indonesia remains insignifi- cant due to adverse government policy and lack of farmer knowledge and skills. The seed lobsters available in Indonesia are primarily Panulirus homarus, a species with excellent production characteristics like P. ornatus, although with lesser value. Extraordinarily high abundance of naturally settling seed lobsters is appar- C. M.
