Index of predation on juvenile salmonids by northern squawfish in the lower and middle Columbia River and in the lower Snake River Index of predation on juvenile salmonids by northern squawfish in the lower and middle Columbia River and in the lower Snake River

We developed a predation index to describe the relative magnitude of predation on juvenile salmonids by northern squawfish Ptychocheilus oregonensis throughout the lower and middle Columbia River and lower Snake River. The predation index was the product of an abundance index and a consumption index. We evaluated various catch indices and found that catch per unit effort best reflected...

Prerelease disease treatment with potassium permanganate for Fall Chinook salmon smolts Prerelease disease treatment with potassium permanganate for Fall Chinook salmon smolts

Standard potassium permanganate treatment (2 mg KMnO4/L freshwater for 1 h on three consecutive days) was applied to presmolts (parr) and smolts of fall chinook salmon (Oncorhynchus tshawytscha). Smoltification was determined by gill Na+,K+-ATPase activity. Treatments were conducted 73, 59, 45, 31, 16, and 2 d prior to full-strength seawater entry in aquaria. Potassium permanganate did...

Characterization of a rhabdovirus isolated from carpione Salmo trutta carpio in Italy Characterization of a rhabdovirus isolated from carpione Salmo trutta carpio in Italy

A virus, strain 583, was isolated from carpione Salmo trutta carpio fry exhibiting high mortality. The virus was not neutralized by rabbit antisera against the fish rhabdoviruses viral haemorrhagic septicaemia virus (VHSV), infectious hematopoietic necrosis virus, eel rhabdovirus European X, spring viraemia of carp virus or pike fry rhabdovirus, or against the birnavirus infectious...

Fluctuating asymmetry and fractal dimension of the sagittal suture as indicators of inbreeding depression in dama and dorcas gazelles Fluctuating asymmetry and fractal dimension of the sagittal suture as indicators of inbreeding depression in dama and dorcas gazelles

The effects of inbreeding on the developmental instability of skulls of dorcas (Gazella dorcas) and dama (G. dama) gazelles were investigated. In total, 132 dorcas gazelle skulls and 74 dama gazelle skulls from the Estación Experimental de Zonas Aridas in Almera, Spain, were measured. The fluctuating asymmetry of 9 meristic characters, consisting of the numbers of foramina on the two...
