“…However, recent studies have demonstrated that bighead and silver carps can adversely affect the water quality and native fish populations. For example, Borics et al, (2000), Cooke et al (2009) and Lin et al (2014) reported that bigheaded carps contributed significantly to the development of high algal biomass and reduced water clarity, while Sampson et al (2009) found considerable diet overlap among native fishes and bigheaded carps, which may cause decreased fitness in native fish populations. In addition, the combined stocking of these species caused a decline in the abundance of cladocerans and copepods in eutrophic lakes in China where bigheaded carps were introduced (Yang et al, 1999;Shao et al, 2001).…”

“…In addition, the combined stocking of these species caused a decline in the abundance of cladocerans and copepods in eutrophic lakes in China where bigheaded carps were introduced (Yang et al, 1999;Shao et al, 2001). Thus, these fishes constitute a considerable ecological threat to aquatic ecosystems where they are not native (Chick and Pegg, 2001;Xie and Chen, 2001;Cooke et al, 2009). Accordingly, bigheaded carp introduction and stocking to natural waters have been stopped and banned in the last decades in several countries, including Hungary (Boros et al, 2014).…”

Key-words:bigheaded carp, gill raker morphology, filter-feeding, food size, plankton Bigheaded carps and especially silver carp have been considered as an effective biological control for algal blooms, thus were introduced to several countries in the last decades, including Hungary. Our aim was to explore the feeding habits of bigheaded carps in Lake Balaton (Hungary), where the stock consists mainly of hybrids (silver carp × bighead carp). We examined the relationship between filtering apparatus (gill raker) morphology and size-distribution of planktonic organisms in the food. We failed to find any significant relationship between gill raker parameters and plankton composition in the filtered material. Bigheaded carps with various types of gill rakers consumed food within the same size-spectrum, independently of the rate of hybridization. However, the linkage between the proportion of different planktonic size classes in the water and in the diet of fish was detectable in case of both phytoplankton and zooplankton consumption, suggesting that the seasonally variable availability of different food items was an important factor in determining the food composition of bigheaded carps. We can deduce that bigheaded carps consume high amounts of zooplankton to meet their energy requirements, and the diet overlap among bigheaded carps and other planktivores may exert negative effects on native fish populations.

“…Dong and Deshang (1994) mentioned that for plankton organisms about 70 μm dia., the removal rates by bighead carp were similar to those by silver carp. Cooke et al (2009) studied the effect of the amount of plankton on the development of bighead carp and they found out that there was a close interrelation between the biomass of the phytoplankton and the fish growth. The authors underlined that the insufficient amount of plankton biomass could be a limiting factor for growth.…”

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: K 1 -one-year old common carp (Cyprinus carpio L.) -500 pcs.ha -1 (half being scale carp and the other half -mirror carp); Tp 1 -oneyear old bighead carp (Hypophthalmichtys nobilis Rich.) -300 pcs.ha -1 ; А 1 -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.

Exportation of Asian carp from the Illinois River to China is an emerging business with ecological and economic benefits. The current market environment supports the shipment of frozen Asian carp to China; however, lack of standardization in harvesting, hauling, and processing techniques present challenges for product quality. The objective of this study was to evaluate seasonal, spatial, and species effects on fillet quality of Asian carp harvested from the Illinois River. As such, Bighead and Silver Carp were harvested on two occasions (summer and fall) from two geographically distinct reaches (Alton and Peoria) of the Illinois River. Lower (P<0.05) fillet pH, Torrymeter freshness values, and higher aldehyde concentrations were observed in fillet coming from fish harvested in summer compared to those harvested in fall. Asian carp caught in the Alton Reach had lower (P<0.05) fillet pH, post-processing freshness values, and higher aldehyde concentrations than those from the Peoria Reach. Summer harvested fish had higher (P<0.05) whiteness values than fall harvested fish. Lower (P<0.05) pH, freshness values, and increased peroxide concentrations were observed in Bighead Carp relative to Silver Carp fillets.This is the first report of color and Torrymeter freshness values for Silver and Bighead Carp. This can establish a reference for future research in commercial evaluation of flesh quality for these two species.Indicators of shelf life suggest improved product quality for a frozen fish export market can be achieved by concentrating harvest on Silver Carp in the Peoria Reach during the fall season.
