Aggregation and vertical migration behavior of Euphausia superba

Deep Sea Research Part II: Topical Studies in Oceanography, 2004
Aggregation and vertical migration behavior of Euphausia superba were studied in Marguerite Bay and its vicinity west of the Antarctic Peninsula using a vessel-mounted, Acoustic Doppler Current Profiler, and a Multiple Opening and Closing Nets and Environmental Sensing System, during the 2001 and 2002 fall US Southern Ocean GLOBEC project cruises.

Peptide hydrolases of Antartic krill, Euphausia superba

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1985
Abstract 1. 1. A survey has been made of the peptide hydrolase activities occurring in Antarctic krill, Euphausia superba. 2. 2. A major protein hydrolyzing activity in the pH range of 6–8, and a minor activity at pH 3–4, were detected. 3. 3. Temperature optima of approx.

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.

Filtration Rates of Euphausia Superba Dana: Under- or Overestimates?

Journal of Crustacean Biology, 1984
ABSTRACT Filtration rates of adolescent Euphausia superba obtained by both constant volume and flow-through techniques are presented. Filtration rate data for a range of particle sizes are presented. An increase in the number of large particles in the water by enrichment with artificial microcapsules results in a shift of the filtration rate efficiency

Biochemical genetics and population structure of Euphausia superba

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1988
Abstract 1. 1. Hydrographical evidence for the existence of separate populations of Euphausia superba has been considered in relation to recent studies on enzyme polymorphism in geographically separated regions of the Southern Ocean. 2. 2. A review of results from studies on genetic variation in the species give strong evidence of genetic ...

Colorimetry of the hepatopancreas in Antarctic krill, Euphausia superba

Polar Biology, 1991
Hepatopancreas color of freshly caught as well as starved Euphausia superba was examined by a chroma meter to express it quantitatively and compare it with plant pigment contents. There was a high positive correlation (r= 0.77) between plant pigment contents of hepatopancreas and the purity (vividness) of hepatopancreas color, and a negative ...

Analysis of fishery operations of the Ukrainian fishing vessel ?????onstruktor Koshkin??? at the Antarctic krill Euphausia superba fishery was given. Reasons of formation and disintegration of its fishery aggregations were considered. Characteristics of krill age-mass composition and biological state were given, as well as spatial distribution features
