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

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.

Names of Larvae in the Decapoda and Euphausiacea

Crustaceana, 1969
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 ...

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.

Volume and Weight Characteristics of Species of Euphausiacea

Crustaceana, 1967
Regressionsgleichungen fur die Relation Korpervolumen zu Korperlange werden fur neun der elf Gattungen von Euphausiaceen berechnet. Die erhaltenen Gleichungen fur dieses Verhaltnis, sowie die fur das Verhaltnis zwischen Korpergewicht und Korperlange bei den Euphausiaceen als Gesamtheit, werden vorgelegt.

Larval development of Euphausia nana (Crustacea: Euphausiacea)

Marine Biology, 1984
The larvae of Euphausia nana Brinton in Sagami Bay and Suruga Bay, Central Japan, are described and illustrated. The furcilia stage is separated into six stages on the basis of the form of the pleopods and the number of terminal telson spines. Furcilia I, no pleopod or non-setose pleopods and seven terminal telson spines.

Bagteriologigal characteristics of Antarctic krill (Crustacea, Euphausiacea)

Sarsia, 1981
Abstract The bacterial flora of two species of Antarctic krill, Euphausia superba Dana and E. crystallorophias Holt & Tattersall, was studied with the aim of investigating the role played by bacteria during the claimed rapid deterioration of these animals.

The organization of the olfactory lobes in Euphausiacea and Mysidacea (Crustacea, Malacostraca)

Zoomorphology, 1992
The structural organization of the olfactory lobes in representatives of euphausiid and mysid crustaceans was investigated and compared, also with these structures described in other crustaceans and in insects. In the investigated euphasiid and mysid species, the olfactory-globular tract and the position of cell clusters associated with the olfactory ...
