Fish feed constitutes one of the largest costs in aquaculture, therefore inefficient feed management will have a negative impact on fish farm economics. Eurasian perch (Perca fluviatilis L.) is a relatively new candidate for freshwater aquaculture, however little is known about the energy requirements of this species. The aim of this study was to develop an energy requirement model for intensive culture of Eurasian perch reared at rational temperatures. Data on growth (the thermal unit growth coefficient, TGC, 3√g · (°C · days)−1) and digestible energy need (DEN, kJ DE · g−1) of Eurasian perch at a size range of 20–180 g and at temperatures of 17–23 °C were used. Regression analysis revealed that both TGC and DEN were affected significantly by fish size (P < 0.001) but not by temperature (P > 0.05). Two models including body size of the fish were developed: (i) an inverse TGC model for evaluation of the daily theoretical weight increment (TWi, g · day−1) and (ii) a linear DEN model. The TGC model was validated by comparing theoretical data with data obtained from a commercial growth trial. By combining the TWi and the DEN, a model describing the daily theoretical energy requirement (TER, kJ · day−1) at different temperatures and for Eurasian perch of different sizes was successfully developed.

“…Temperature during ongrowing season highly affected perch production ranging from 15 to 160 g · m −3 · day −1 when fi sh were reared under relatively high fi nal density (30 kg · m −3 ) . Fontaine et al ( 1996 ) recommended using the pond -cage combination system for perch farming. In this system, 1-year old perch of 10-20 g body weight were harvested from ponds during spring and subsequently cultured in cages for two summer seasons.…”

Three different production systems are used for perch ongrowing: (1) traditional extensive polyculture system, (2) semi-intensive culture farming and (3) intensive perch farming under RAS (Recirculating Aquaculture System(s)). Extensive and semi-intensive culture systems have many production limitations. Therefore, intensive perch farming has been developed in Europe for more continuous and predictive marketable perch production.Marketable perch production under RAS is affected by several main factors of production system. Optimal value and condition of each factor for stable and maximal perch production under RAS are described and recommended in details in this chapter.Overall, white, grey and black tank walls with light regime 12L:12D or 18 L:8D and light intensity 200-1,100 lx create optimal light conditions for intensive ongrowing perch culture. Freshwater or water with salinity under 4 ‰ with temperature 22-24 °C, oxygen saturation around 60-72 % and very low ammonia (below 0.3 mg N-NH 3 · L −1 ) and nitrite (below 0.5 mg NO 2 − · L −1 ) concentrations are optimal conditions for intensive perch production. Disturbance (cleaning of tanks, fi sh size-sorting etc.) must be reduced at minimum level for providing of maximal production which is the highest under optimal fi sh biomass from 10 to 20 kg · m −3 for 10 g perch to 60-70 kg · m −3 for 150 g perch under RAS.

A preliminary study of parasites and diseases of perch in an intensive culture system

The recent development of intensive rearing of European perch Perca fluviatilis in warm water effluents revealed important pathological problems. This study gives a preliminary overview of parasites and diseases encountered in experimental perch farming. No virus has been recorded since the beginning of the experiments in 1993. By contrast, mass mortality caused by bacterial disease alone or associated with other pathogens were frequently observed. The main identified bacterial species were: Aeromonas sp., A. veronii, A. hydrophila, Streptococcus sp., Staphylococcus sp., Vibrio fluviatilis and Enterobacter agglomerans. Protozoans were the most common parasites observed on cultured P. fluviatilis. High mortality rate due to Ichthyobodo necator and Trichodina sp. may take place at different stages of perch rearing. In contrast, the infestation by Ambiphrya sp. and Heteropolaria sp. was size‐ or age‐related; these two ciliates infested perch weighing < 1 g and > 20 g, respectively. In spite of the presence of other parasites such as Ichthyophthirius multifiliis, Hexamita spp., Gyrodactylus sp. and Argulus sp. in the rearing system P. fluviatilis does not appear to be affected. Further abnormalities or diseases inherent to intensive culture systems are also described.
