Control of reproductive function in captivity is essential for the sustainability of commercial
aquaculture production, and in many fishes it can be achieved by manipulating photoperiod …

Abstract The European eel (Anguilla anguilla Linnaeus 1758) is a species typical for waters
of Western Europe. Thanks to early expeditions on the Atlantic Ocean by the Danish …

Oogenesis in fishes follows a universal plan; yet, due to differences in the synchrony and
rate of egg development, spawning frequency varies from daily to once in a lifetime. Some …

Eel populations worldwide are dangerously close to collapsing. Our study is the first to show
that current levels of dioxin-like contaminants are strong candidates because of their …

Remarkable progress in techniques for maturation of adults and rearing of larvae has been
achieved for the J apanese eel A nguilla japonica over the past 50 years, but recent efforts …

Standardization of artificial fertilization protocols for the European eel, Anguilla anguilla, is a
prerequisite for optimizing the use of available gametes in hatchery facilities and for …

Many wildlife populations are declining at rates higher than can be explained by known
threats to biodiversity. Recently, thiamine (vitamin B1) deficiency has emerged as a possible …

High-quality eggs are essential for the sustainability of commercial aquaculture production.

Abstract The European eel migrates 5,000–6,000 km to the Sargasso Sea to reproduce.
Because they venture into the ocean in a pre-pubertal state and reproduce after swimming …

Deteriorating reproductive capacities are a possible cause for the decline in eel populations.
However, since no sexually maturing adults have ever been found in the open ocean, there …
