| microsporidiosis in the caribbean spiny lobster panulirus argus from southeast florida, usa. | two specimens of the caribbean spiny lobster panulirus argus captured by lobster fishers offshore of southeast florida, usa, between late 2007 and early 2008 had completely white abdominal muscle tissue with a 'cooked' appearance. wet-mount examination of the skeletal muscle tissue revealed masses of microsporidian spores. histopathology of longitudinally sectioned skeletal muscle showed that the microsporidian spores displaced much of the muscle mass, but were interspersed with small empty vacu ... | 2009 | 19565701 |
| neurolipofuscin is a measure of age in panulirus argus, the caribbean spiny lobster, in florida. | accurate age estimates for panulirus argus, the commercially important caribbean spiny lobster, would greatly enhance life history and population analyses. most age approximations of p. argus are based on size and growth data, but size is generally considered a poor proxy for age of crustaceans in the field because of numerous environmental, density-dependent, and fishery-related factors. an established technique for aging crustaceans, employing histologically determined lipofuscin content in th ... | 2007 | 17679720 |
| a new pathogenic virus in the caribbean spiny lobster panulirus argus from the florida keys. | a pathogenic virus was diagnosed from juvenile caribbean spiny lobsters panulirus argus from the florida keys. moribund lobsters had characteristically milky hemolymph that did not clot. altered hyalinocytes and semigranulocytes, but not granulocytes, were observed with light microscopy. infected hemocytes had emarginated, condensed chromatin, hypertrophied nuclei and faint eosinophilic cowdry-type-a inclusions. in some cases, infected cells were observed in soft connective tissues. with electro ... | 2004 | 15212276 |
| predator-induced behavioral and morphological plasticity in the tropical marine gastropod strombus gigas. | florida queen conch stocks once supported a significant fishery, but overfishing prompted the state of florida to institute a harvest moratorium in 1985. despite the closure of the fishery, the queen conch population has been slow to recover. one method used in the efforts to restore the florida conch population has been to release hatchery-reared juvenile conch into the wild; however, suboptimal predator avoidance responses and lighter shell weights relative to their wild counterparts have been ... | 2002 | 12200261 |
