Aquaculture of Cyprinids
Cyprinids are the most widely farmed fish in the world (total annual
production : 2 million tons), and include very ancient domesticated species
of carp.
Goldfish and some varieties of oramental colored carp have been
selected for certain of their morphological aspects, thus generating a geeat
variety of strains. Many cyprinids are also caught by angling, and phyto—
phageous and herbivorous carp are used to control the vegetation in different
bodies of water.
Cyprinids have many advantages, as far as farming is concerned, such as
the ability to stand a wide range of temperatures and oxygen levels and to
feed at different levels of the trophic chain; it is not surprising that
these fish have a wide distribution and a high production.
However, in spite of the fact that they have been domesticated for many
years
and
that many tons
are
produced, their farming has been little studied
and there are few data on their biology. As cyprinids are usually farmed in
ponds and feed on renewable sOurces of the aquatic ecosystem, it is necessary
to know more about the environment and procure the means of controlling the
whole ecosystem well. Finally, in their original state, these species have
little commercial value in developed countries and must be processed before
being offered to consumers. Thus, research and technological development
should be centered on the environment, the animal, and its processing.
This volume presents reviewed papers given at the symposium by inter—
national specialists and summarizing the actual state of knowledge and
techniques in the main fields of cyprinid farming; nutrition, reproduction,
genetics, larva rearing, growth in ponds, farming practices, pathology,
processing and economy.
During this symposium, original results were also presented in posters
at
the end of each session.
Summaries of these posters
(not reviewed) are
presented in this volume as well as round table conclusions edited by the
session preSidents. Some of the posters have been published in a special
issue of Aquaculture volume 54, 1986. The present volume is not a treatise
on
cyprinid farming but
a
review that brings up to date existing works
(Schaperclaus, 1962; Huet, 1970)
in the field.
Two hundred and fifty people from 26 countries attended the symposium
organized in France near Paris. The aim was to bring together Central
European specialists (invited as part of a bilateralexchange program with
France) and the rest of international scientific and technical community.
Simultaneous interpretation by members of the INCCA (Mrs Chave, Perdereau
and Sukthankar) permitted French fish farmers to participate also.
