| aphanomyces invadans and ulcerative mycosis in estuarine and freshwater fish in florida. | in the spring of 1998, the florida fish and wildlife research institute received numerous reports of lesioned or ulcerated fish primarily from the st. lucie estuary on the southeast coast of florida, an area known since the late 1970s for lesions of the ulcerative mycosis (um) type. from these and archived reports, as well as others received from different areas of florida, we documented that diseased specimens had randomly distributed skin ulcers (usually reddened or hemorrhagic) with raised ir ... | 2007 | 18236628 |
| yolked oocyte dynamics support agreement between determinate- and indeterminate-method estimates of annual fecundity for a northeastern united states population of american shad. | reports of american shad fecundity identify two important themes regarding egg production in fishes. first, geographic variation occurs and is biologically meaningful. shad annual fecundity decreases with increasing latitude, but predicted lifetime fecundity does not, because of a counter-gradient of survival probability, all of which can explain the adaptive significance of natal homing. second, the appropriate method of measuring fecundity depends on the pattern of oocyte development. historic ... | 2016 | 27716845 |
