Rates of oxygen consumption (R: μl O2 [individual]−1 h−1), and ammonia excretion (E: μg NH4-N [individual]−1 h−1), O:N ratios (by atoms) and body water contents (% of wet mass [WM], as an index of lipid accumulation) of Euphausia pacifica and Thysanoessa

Distribution and population structure of Thysanoessa inspinata were investigated off northeastern Japan and compared with those of Euphausia pacifica and other Thysanoessa species. Thysanoessa inspinata were distributed as widely as E. pacifica, but their

We studied seasonal and regional change in vertical distribution and DVM patterns of four euphausiid species (Euphausia pacifica, Thysanoessa inspinata, Thysanoessa longipes, and Tessarabrachion oculatum) from two years of surveys using MOCNESS above

Over a period of five years (1997–2002) the euphausiid Thysanoessa inspinata has been recorded in plankton samples from the eastern Gulf of Alaska, as far north as 59°N. Until recently the northern limit of distribution of the species was assumed to be

The abundance and population structure of Euphausia pacifica and Thysanoessa inspinata were investigated during the period 9 March–29 April 2007 at a single station in the Oyashio region. Water temperature and chlorophyll a concentration varied from 1.1
