scientists. Multiple research pathways have been explored, with emphasis of
the causes of mortality affecting principally the early developmental stages
of fish life. The small data set presented focuses on a feature often inadequately
considered, i.e., the nutritional condition of the breeding parent fishes estimated
from the levels of the RNA/DNA ratio determined in fish white muscle. This is
applied to the European anchovy population inhabiting the French continental
shelf of the North-east Atlantic Ocean. In four of the five years analysed,
the annual recruitment shows a tight relationship with the mean values for the
RNA/DNA ratio determined in the parent fish during the previous breeding season.
One year is clearly distinguished from this model, owing to a strong drop of
the recruitment, of which an explanation is tentatively advanced. This drop
coincides with the beginning of a strong collapse of the population. A very
low level of the anchovy biomass will last ten years. The role of the nutrition
of breeding fish in the recruitment success is discussed in connection with
the literature that emphasized the importance of conditions providing fish with
sufficient fuel during the crucial period of its gametogenesis, particularly
in clupeoids and anchovies.]]>Ahmed, Z.F. and T. Ozawa,2002Engraulis japonicus) in Kagoshima bay, Southern Japan.]]>5728732Ahmed, Z.F., T. Ozawa, T. Hayama and Y.
