| nematode infestation of fillets from atlantic cod, gadus morhua, off eastern canada. | the prevalence and intensity of larval nematodes in fillets of atlantic cod, gadus morhua, were examined and compared with similar data from a previous survey conducted about 30 yr ago. anisakis simplex occurred more often in the nape of the fillet, whereas pseudoterranova decipiens was the predominant species in napeless fillets. the results suggest an increase in both the prevalence and intensity of p. decipiens in fillets of cod, especially those originating from the gulf of st. lawrence and ... | 1988 | 3193325 |
| larval nematodes infecting amphiporeia virginiana (amphipoda: pontoporeioidea) on sable island, nova scotia. | three species of larval nematodes were found infecting the nearshore subtidal amphipod amphiporeia virginiana collected from beaches on sable island, nova scotia. five and 2 sealworms, pseudoterranova decipiens s.l., were found in 2,020 and 2,044 amphipods, respectively, collected in 1991 and 1992, dissected, and examined microscopically. two sealworms, 1 paracuaria adunca and 1 ascarophis sp., were found in 5,157 amphipods collected in 1992 and enzymatically digested. infection with each specie ... | 1993 | 8277392 |
| settling rate and dispersal of sealworm eggs (nematoda) determined using a revised protocol for myxozoan spores. | settling rates and densities of small bodies can be determined by recording settling rates in fluids of different densities, but similar viscosities, and applying stoke's law. however, at low reynolds numbers, drag effects reduce the object's settling rate and must be accounted for in sedimentation experiments. using a revised protocol for spores of the myxozoan henneguya doori that accounted for significant drag effects exerted by the experimental apparatus, we improve upon a previously describ ... | 1997 | 9105296 |
