Early life history of Japanese anchovy Engraulis japonicus off the Pacific coast of Japan

概要

The early life history of fish involves various aspects of morphology, ecology,
behavior, growth, and development from egg to juvenile stages, and is the primary focus
of research in fisheries ecology. The early life history of fish and its role in recruitment
processes has given rise to successive studies in fisheries. During the early life stage,
survival rates can determine subsequent recruitment (Hjort 1914). Early life traits, like
larval growth rates and spawning/hatching dates, have been proven to be crucial
features in improving our understanding of processes potentially affecting recruitment
and subsequent life stages (Contreras et al. 2013, Di Franco et al. 2013).
Several hypotheses have been proposed to explain and project the fluctuations in
the production of small pelagic fish, fixating on the early-life-history components of
fish such as body size, growth rate, and reproduction.
Traditional approaches to studying causes of recruitment fluctuation in marine
fishes are often based on the premise that there is a single, clearly identifiable factor
responsible for the annual production of marine fishes (Anderson 1988). ...
