| experimental studies on the infectivity of anguillicola crassus third-stage larvae (nematoda) from paratenic hosts. | the swimbladder parasite anguillicola crassus kuwahara, niimi et itagaki, 1974 (nematoda: dracunculoidea) is a well-known pathogenic parasite of the japanese and european eels. numerous studies on the life cycle of the parasite have revealed the involvement of a copepod or an ostracod intermediate host and a fish paratenic host, in which the third-stage larvae (l3) infective to the eel develop. the present study comprised infection experiments with the larvae of a. crassus. these experiments can ... | 1996 | 9061901 |
| within-lake distribution patterns of fish assemblages: the relative roles of spatial, temporal and random environmental factors in assessing fish assemblages using gillnets in a large and shallow temperate lake. | in this study, the relative role of spatio-temporal factors and associated environmental variables (water transparency and temperature) were quantified in relation to gillnet samples of fishes in a large and shallow lake (lake balaton, hungary). most of the variance (56·1%) in the relative abundance data (%) was related to the vertical segregation of fishes. this gradient substantially affected the catch per unit effort (cpue) by number of the dominant species, the surface-oriented bleak alburnu ... | 2013 | 23464547 |
