TL;DR: Young salmon and trout ordinarily take little food from about 10 p.m. to about 5 a.m, but this does not seem to be entirely due to changes in temperature or light conditions.
Abstract: Young salmon and trout ordinarily take little food from about 10 p.m. to about 5 a.m. This does not seem to be entirely due to changes in temperature or light conditions. It seems probable that the...

TL;DR: Rainfall after long period of drought brought the salmon from the sea into the river to die where water was shallowest and without cascades, therefore warmest, and the very high temperatures and deaths occurred in afternoon from sun's heat and at ends of periods of days with moist air from the ocean and mounting water temperatures, dew point temperatures and mimimal air temperatures.
Abstract: Deaths in Moser river, N.S., in 1939 were at time of day, on days, and in locality with highest water temperature. Symptoms were loss of sensitivity to light and very rapid breathing with recovery ...

TL;DR: Artificial spawning beds were prepared and were promptly used by the salmon, providing a means of extending the area for successful natural spawning in Moser river, Nova Scotia.
Abstract: Atlantic salmon select as redd sites places where the current is accelerating. Eggs in the redd are in definite pockets associated with large gravel and stones, and are not scattered through the re...

TL;DR: The cutthroat were more piscivorous than the brown trout, and a definite selection of food by the trout was indicated.
Abstract: Stomach contents of 293 rainbow, 160 cutthroat and 113 brown trout were examined and analyzed according to species, size groups (5 cm.) and habitat (river or lake). For rainbows of both river and l...

TL;DR: Growth of the obligate anaerobes Clostridium botulinum and C. sporogenes is inhibited by 0.02 per cent sodium nitrite in fish digest broth at acid pH, inhibition not being accentuated by brief expo...

TL;DR: The contact plate method as used for cod muscle has revealed that the major changes rendering fish unfit for human consumption can be attributed almost entirely to surface pollution of the fish with spoilage bacteria.

TL;DR: Heavy infestations of this copepod in various developmental stages occur on Salmo salar and Salvelinus fontinalis at Moser River, N.S. Metanauplius a...
Abstract: Heavy infestations of this copepod in various developmental stages occur on Salmo salar and Salvelinus fontinalis at Moser River, N.S. Males and females occur in about equal numbers. Metanauplius a...

TL;DR: The distances moved in response to varied stimuli are measured, at constant temperature, by a new method using a sigmoid curve, which shows the relation between strength of stimulus and distance moved.

TL;DR: In the sea, brook trout travel in schools along the sea shore and feed largely upon small fishes of various species and upon Crustacea.

TL;DR: On removal of scales in the smolt new scales develop in the scale pockets, attaining normal width in 40 days, but not quite normal length even by 59 days, and initial growth is very rapid and without circulus formation.

TL;DR: In whole and in comminuted muscle at its natural pH, free drip is almost completely inhibited, and expressible drip greatly reduced, by incorporation of about 1 per cent NaCl.
Abstract: Sodium chloride prevents drip in lightly brined fish muscle by causing the proteins to swell and to bind liquid firmly, and not by a surface sealing action. In whole and in comminuted muscle at its...
TL;DR: Red halophiles have high resistance to ultra-violet light, surviving 120 minutes' exposure, and range of salt tolerance can be increased in both directions by gradual adaptation.
Abstract: Growth of 25 strains of red halophiles stopped below 15° and above 55°; heat resistance is less than two minutes at 98 °C. in 24 per cent saline. Range of relative humidity necessary for growth lie...
TL;DR: Statistical treatment of vertebral counts of young herring taken along the southeast coast of Vancouver island demonstrates significant differences between localities in the same year and in the the same locality in different years.

TL;DR: Twenty-four samples of seawater, fish slime and intestinal contents, taken off Halifax harbour, yielded two red halophilic sarcina strains from codfish slime.

TL;DR: The products of fermentation of glucose by "resting cell" suspensions of certain bacteria isolated from decomposing cod muscle include lactic acid, acetic acid, formic acid, ethyl alcohol, carbon dioxide and small amounts of acetylmethylcarbinol.
Abstract: The products of fermentation of glucose by "resting cell" suspensions of certain bacteria (Serratia, Achromobacter, and Micrococcus) isolated from decomposing cod muscle include lactic acid, acetic...
TL;DR: Spoilage, as measured by rise in trimethylamine and bacterial content, of cod press-juice containing 21.0 g.
Abstract: Spoilage, as measured by rise in trimethylamine and bacterial content, of cod press-juice containing 21.0 g. salt per 100 ml. (approximately 80 per cent saturated) is delayed longest with pure sodi...
TL;DR: Curing salt mixtures containing 2% sodium acid phosphate and 0.25 per cent sodium benzoate stopped growth of red halophiles as well as brown halophilic dun molds and dips in preservative solutions are not effective.
Abstract: Fumigation with formaldehyde or sulphurous acid vapours was found effective against directly exposed red halophiles, using 10 oz. (283 g.) of the former or 5 lb. (2.268 kg.) sulphur per 1,000 cu. f...
TL;DR: In vitamin A (colorimetric) and vitamin D (biological) assays on representative seasonal samples of commercially produced pilchard and herring oil (from the whole fish), the vitamin D potency was high in both colorimetric and biological tests.

Abstract: Nymphon glaciale, N. serratum, Pallenopsis longirostris and Ammothea scabra are recorded for the first time from the Canadian Atlantic coast.
