THE RELATION BETWEEN THE SCATTERING LAYER AND THE EUPHAUSIACEA

The Biological Bulletin, 1950
The source of the scattering effect is not, at present, susceptible of direct proof, but if an organism could be found whose characteristics agreed with those of the layer on a sufficient number of points, then there would be a high probability that this is the actual source of the effect. From the diurnal migration of the layer there seems no room for

Growth of Nyctiphanes (Euphausiacea) on different diets

Journal of Experimental Marine Biology and Ecology, 2003
Abstract To determine the effects of diet on the growth rate of Nyctiphanes australis (Euphausiacea), metanauplii were reared to mature adults in the laboratory. Sibships (siblings from the same mother) were raised on different food items collected from the field and cultured in the laboratory. A sibship was divided at the calyptopis stage and 50% of

Feeding appendages of the Euphausiacea (Crustacea)

Journal of Zoology, 1967
The Euphausiacea comprises about 85 species and the structure of the feeding appendages of 68 of these species is discussed here. A considerable uniformity is apparent in the appendages throughout the order but generic, and even in some cases, specific differences are evident.

of Rhode Island, 1965). Schroeder obtained trawl catches of up to 245 crabs per hour's fishing in the waters off the coast from Nova Scotia to Virginia; the best catches were made between 150 and 550 fm (274 and 1,005 m). The crabs were mostly large, measuring 4 to 5^2 inches (102 to 140 mm) across the carapace, weighing up to 2 lb (0.91 kg) or a ...

Karyological Study of the Mediterranean Krill Meganyctiphanes norvegica (Euphausiacea)

Journal of Crustacean Biology, 1995
The chromosomes of Meganyctiphanes norvegica from the Mediterranean Ligurian Sea were investigated using standard Giemsa, silver staining, and C-banding. The karyotype of both sexes consists of 19 metacentric chromosome pairs of gradually decreasing size.

EUPHAUSIACEA AND MYSIDACEA FROM WESTERN CANADA

Contributions to Canadian Biology and Fisheries, 1933
An account of a collection of Euphausiacea and Mysidacea made in the waters of British Columbia by Miss A. A. Berkeley and Mr. G. H. Wailes, with summary of all previous records, so that the paper represents a complete account of the western Canadian species of these two groups of Crustacea, with a full list of references to the literature of west ...

Ordre des Euphausiacea Dana, 1852

Crustaceana, 2003
[This paper presents the current state of our knowledge on the Euphausiacea, and is to be published eventually in Grasse's "Traite de Zoologie". The main characteristics of the order are listed and the external morphology is examined. The axial organization of the cephalothorax has led to an original study of the exoskeleton, the internal invaginations

Development of the Stomach in Euphausia Superba Dana (Euphausiacea)

Journal of Crustacean Biology, 1993
ABSTRACT Development of the stomach, with emphasis on the filter system, was investigated in the metanauplius, calyptopis, and furcilia stages of the Antarctic krill Euphausia superba. The metanauplius lacks an elaborated stomach as well as a connection between the esophagus and the midgut. In calyptopis I, the stomach becomes functional.
