Abstract

An experiment on slaughter characteristics of bighead carp (Hypophthalmichtys nobilis Rich.) reared in polyculture of the
same age, based on natural feeding in the ponds, was carried out at the Institute
of Fisheries and Aquaculture – Plovdiv, Bulgaria. Some of the ponds (First
Group) were not fertilized and others (Second Group) were supplemented with
manure at the rates corresponding to the standards of organic production. The structure of polyculture was one and
the same in all the ponds: K₁– one-year old common carp (Cyprinus carpio L.) – 500 pcs.ha^-1 (half being scale carp and the
other half – mirror carp); Tp₁ – one-year old bighead carp
(Hypophthalmichtys nobilis Rich.) – 300 pcs.ha^-1; А₁  – one-year old grass carp (Ctenopharyngodon idella Val.) – 100 pcs.ha^-1. The bighead carp
reached a live weight of 0.766
kg
under the experimental conditions, the fishes in the ponds fertilized with
manure being about 13.6% heavier compared
to fishes in the ponds of the other group. It was established that the
slaughter yield and the relative share of the fillet in bighead carp were in
average 54.3% and 35.4%, respectively, and, pond
fertilization and the amount of phytoplankton did not have a statistically
significant effect on fish development. The pond had a significant effect
exerted through its area and by overgrowing with macrophytes. Infestation
increase by up to 30% had a positive effect on the weight of the cleaned
carcass, the fillet and the slaughter output.
