Abstract Casitas are artificial shelters used by fishers to aggregate Caribbean spiny lobsters (Panulirus argus) for ease of capture. However, casitas may function as an ecological trap for juvenile lobsters if they are attracted to casitas and their growth or mortality is poorer compared with natural shelters. We hypothesized that juvenile lobsters may be at particular risk if attracted to casitas because they are less able than larger individuals to defend themselves, and do not forage far from shelter. We compared the nutritional condition, relative mortality, and activity of lobsters of various sizes in casitas and natural shelters in adult and juvenile lobster-dominated habitats in the Florida Keys (United States). We found that the ecological effects of casitas are complex and location-dependent. Lobsters collected from casitas and natural shelters did not differ in nutritional condition. However, juvenile lobsters in casitas experienced higher rates of mortality than did individuals in natural shelters; the mortality of large lobsters did not differ between casitas and natural shelters. Thus, casitas only function as ecological traps when deployed in nursery habitats where juvenile lobsters are lured by conspecifics to casitas where their risk of predation is higher. These results highlight the importance of accounting for animal size and location-dependent effects when considering the consequences of habitat modification for fisheries enhancement.

Sharing Patterns

Spiny lobsters (Palinuridae) commonly share crevice shelters with conspecifics, a behaviour usually hypothesized to benefit mutually cooperative defenders through reduced predation risk. The group-defence hypothesis predicts a suite of distinct corollary life history traits and ecological correlates including more frequent co-denning than solitary denning, especially where predators or den competitors are numerous and when the lobsters are small, moulting or otherwise vulnerable. Two alternative co-denning hypotheses, the dilution effect (a type of selfish herding) and the guide effect (attraction to a denned conspecific), have different and distinctive sets of predictions. To test among these hypotheses, the den-sharing patterns of newly emerged postalgal juveniles of Panulirus argus and associated ecological conditions in the Florida Bay (USA) nursery habitat were examined. Only half of the juveniles shared dens, and rarely was den sharing in an area greater than that expected by chance. Den-sharing frequency was most highly correlated with conspecific density and scarcity of local dens. The lack of correlation between den sharing and lobster size, moult condition, shelter type and predator density failed to support either the group-defence or the dilution-effect hypothesis. Instead, the data better support the guide-effect hypothesis.
