Aphanomyces invadans in Atlantic Menhaden along the East Coast of the United States Aphanomyces invadans in Atlantic Menhaden along the East Coast of the United States
The cause of deeply penetrating ulcers of Atlantic menhaden Brevoortia tyrannus has been the subject of significant research efforts in recent years. These lesions and the associated syndrome termed ulcerative mycosis have been observed along the East Coast of the United States since at least the early 1980s. Although Aphanomyces spp. were isolated from these lesions in the mid to late...

Induction of skin ulcers in Atlantic menhaden by injection and aqueous exposure to the zoospores of Aphanomyces invadans Induction of skin ulcers in Atlantic menhaden by injection and aqueous exposure to the zoospores of Aphanomyces invadans
The infectivity and role of Aphanomyces invadans in the etiology of skin ulcers in Atlantic menhaden Brevoortia tyrannus were investigated with two laboratory challenges. In the first experiment, Atlantic menhaden received subcutaneous injections with secondary zoospores from one of three cultures of Aphanomyces: WIC (an endemic isolate of A. invadans in Atlantic menhaden from the...

Illustrated field guide for assessing external and internal anomalies in fish Illustrated field guide for assessing external and internal anomalies in fish
Procedures are described for processing fish for examination of external and internal anomalies and pathologies indicative of exposure to environmental contaminants and other peturbations. For the procedures described here, fish are captured (preferably by electrofishing) and held alive until processing (generally 1 h). Fish are weighed, measured, and necropsied, and a scale sample is...

A comparison of susceptibility to Myxobolus cerebralis among strains of rainbow trout and steelhead in field and laboratory trials A comparison of susceptibility to Myxobolus cerebralis among strains of rainbow trout and steelhead in field and laboratory trials
Three strains of rainbow trout and steelhead Oncorhynchus mykiss were evaluated for the presence of whirling disease in field and laboratory trials. In the field exposures, fingerling Salmon River steelhead and Cayuga Lake and Randolph strains of rainbow trout were placed in wire cages in an earthen, stream-fed pond in New York State that was known to harbor Myxobolus cerebralis. Control...

Effects of whirling disease on selected hematological parameters in rainbow trout Effects of whirling disease on selected hematological parameters in rainbow trout
Hematological responses to whirling disease in rainbow trout (Oncorhynchus mykiss) were investigated. Two-mo-old fingerling rainbow trout were exposed to cultured triactinomyxon spores of Myxobolus cerebralis at 9,000 spores/fish in December, 1997. Twenty-four wks post-exposure, fish were taken from infected and uninfected groups for peripheral blood and cranial tissue sampling...

Utility of splenic macrophage aggregates as an indicator of fish exposure to degraded environments Utility of splenic macrophage aggregates as an indicator of fish exposure to degraded environments
The utility of splenic macrophage aggregates (MAs) as an indicator of fish exposure to degraded environments was evaluated in several species of estuarine fishes as part of the Environmental Protection Agency's Environmental Monitoring and Assessment Program–Estuaries (EMAP-E). Using image analysis, we measured the number and mean size of MAs per square millimeter on tissue sections of...
