Infection of brown trout with Diphyllobothrium dendriticum procercoids

International Journal for Parasitology, 1997
The aims of this experimental study were to develop a practical method of controlling the number of Diphyllobothrium dendriticum procercoids delivered to a fish host; to examine the effect of different procercoid doses (3, 7 and 15) on the plerocercoid level in fish; and to examine the potential mortality caused by plerocercoids.

Cerebellar Regulation of Sensorimotor Activity in Brown Trout

Brain, Behavior and Evolution, 2002
Evoked field potentials were recorded from the mesencephalic (‘optic’) tectum, cerebellar corpus, midline rhombencephalon, and spinal cord of decerebrated brown trout in response to single electrical shocks given to an optic nerve. Evoked responses were also recorded from the rhombencephalon and spinal cord following stimulation (singly and with trains)

Fin Regeneration in Brown Trout

Transactions of the American Fisheries Society, 1943
Abstract In recent years, fin-clipping has become a widely-used method of distinctively marking fish for future identification. A check on possible regeneration in this type of marking is desirable. The following paper presents data on the clipping of ventral fins of yearling brown trout for two successive years.

The brown trout and quantitative ecology

1994
Abstract Most readers must have seen a brown trout, if only as one about to be cooked or eaten. They should have noted several features that facilitate manoeuvrability and sustained swimming (Fig. 1.1): a streamlined body covered with overlapping scales; single dorsal and anal fins to prevent rolling and yawing; paired pectoral and ...

Triploid progeny from a female Atlantic salmon × brown trout hybrid backcrossed to a male brown trout

Journal of Fish Biology, 1996
A female Atlantic salmon × brown trout hybrid was backcrossed to a male brown trout. Electrophoretic analysis of diagnostic enzymes showed that the progeny were triploid. However, a few individuals were partially diploid.

Growth and energetics of brown trout

1994
Abstract The literature on fish energetics and growth has increased markedly during the last 20 years and has been summarized in several excellent reviews, mostly as chapters in larger, multiauthored books (Webb 1978; Brett and Groves 1979; Braaten 1979; Elliott 1979, 1981, 1982; Fischer 1979; Ricker 1979;Ursin 1979; Cho et  al.

Food of anadromous brown trout at sea

Journal of Fish Biology, 2001
The food of migratorySalmo truttain coastal marine waters along the Norwegian Skagerrak coast varied significantly with age, season and habitat of the fish. The main prey categories in terms of frequency of occurrence were fishes followed by crustaceans, surface insects and polychaetes.

Validity of Age Determinations from Scales of Brown Trout, Rainbow Trout, and Brook Trout

Transactions of the American Fisheries Society, 1954
Abstract A total of 1,055, scale samples from tagged, recaptured brown trout, rainbow trout, and brook trout and 129 scale samples from planted, marked rainbow trout were taken from Prickley Pear Creek, Montana, between June 1949 and October 1951. In addition, scale samples were obtained from 69 rainbow trout planted as fry in Savage Lake, Montana, and

Rainbow Trouts And Brown Trouts In European Rivers. Do They Compete?

1997
No abstracts are to be cited without prior reference to the author.Oncorhynchus mykiss, the rainbowtrout, was introduced from the western United States toEurope in 1880. It became, next to the european carp, the most important fresh water fish forfish farming in many countries.
