Feeding Habit of Pond Smelt (Hypomesus transpacificus nipponensis) and Its Impact on the Zooplankton Community in Lake Suwa, Japan

Journal of Freshwater Ecology, 2005
ABSTRACT We examined the feeding habit of pond smelt (Hypomesus transpacificus nipponesis) and its impact on the zooplankton community in Lake Suwa, Japan, from May to December 2001. Stomach contents were analyzed, and prey importance and the prey selectivity index were estimated from the stomach contents of fish and prey density in the lake.

Long-Term Seasonal Trends in the Prey Community of Delta Smelt (Hypomesus transpacificus) Within the Sacramento-San Joaquin Delta, California

Estuaries and Coasts, 2016
Abiotic factors and species introductions can alter food web timing, disrupt life cycles, and change life history expressions and the temporal scale of population dynamics in zooplankton communities. We examined physical, trophic, and zooplankton community dynamics in the San Francisco Estuary, California, a highly altered Mediterranean climate ...
