“…Fish species examined in this study also exhibit different feeding ecology, although most fish feed on plankton during at least some period of their lives (Lazzaro 1987). Some of the most heavily infected species (ruffe, brown bullhead and gudgeon) are benthic fishes.…”

The host specificity and population dynamics of Anguillicola crassus in a number of paratenic hosts were investigated. Various freshwater flsh species were sampled monthly (March 1990 to March 1991) from the Kolenhaven (Albertcanal, Genk, Belgium) and examined for L3-larvae of Anguillicola crassus. Sixteen species were found to be infected: all the physoclist species examined (Gymnocephalus cernua, Lepomis gibbosus, Ictalurus nebulosus, Stizostedion lucioperca, Gasterosteus aculeatus, Oreochromis niloticus and Perca fluviatilis) and those physostome species of which a sufficient number could be examined to detect the infection (Gobio gobio, Leuciscus cephalus, Chondrostoma nasus, Leuciscus leuciscus, Alburnus alburnus, Leuciscus idus, Scardinius erytrophthalmus, Rutilus rutilus and Tinca tinca). There were large differences in prevalence among the fish species examined but generally the prevalence was higher in physoclist fishes and was highest in G. cernua ( 9 6 % ) . In 4 species there was a significant positive correlation between fish length and parasite abundance. The percentage of grown larvae varied among fish species, being lowest in G. cernua and highest in P. fluviatilis. No clear seasonal incidence cycle was observed.

“…Foraging of most planktivorous fish is directed by vision (Lazzaro, 1987), thus that factor can determine the abundance of some aquatic communities, especially crustaceans (Estlander et al, 2009). Planktonic crustaceans can be protected against predation by water turbidity, for suspended particles severely disturb prey detection by fish due to their effects on light scattering (Horppila et al, 2004).…”

-The role of environmental factors in aquatic ecosystems results from basic lake characteristics, human disturbances ('cultural eutrophication') and climate-related trends in the physical and chemical components of lakes. Although the influence of environmental factors on the abundance of aquatic animals is fairly well documented, less has been done to research their influence on food web interactions. The aim of the study was to evaluate microbial and classical food webs in lakes, with special emphasis placed on the role of environmental factors as influencing strengths. Variation partitioning, based on redundancy analysis, revealed that environmental factors played the most important role in structuring aquatic communities by accounting for 87.5% of their variation. Among all the factors measured, total solids (TS), transparency (Secchi disc) and temperature were most closely related to the variation in trophic communities. The analyses of food web interactions under low and high levels of those factors revealed that they differently influenced strengths among food web components. The strongest relations among distinct trophic levels were found under conditions of low TS, the lowest number of relations was found under conditions of low temperature. Only in low TS did bacteria correlate significantly with biogenes. Under high TS, bacteria positively influenced plenty of higher trophic levels. Top-down control was observed under conditions of high temperature. Conditions of low and high transparency did not diversify food web interactions. The obtained results can broaden our knowledge of the response of food webs to environmental factors in advanced stages of global eutrophication of water bodies and in the early stage of projected trends of global climate change.

“…Furthermore, it has often been reported that fish such as tilapia, by recycling nutrients through excretion, eventually promote the production of phytoplankton in ponds and lakes (McQueen et al, 1986;Drenner et al, 1987;Lazzaro, 1987;Northcote, 1988;Elser et al, 1990). Without algal biomass control, an excessive algal bloom may occur, followed by a collapse of the algal population, an increase in ammonia concentration and an oxygen depletion (Rimon and Shilo, 1982).…”

An integrated fish–plankton aquaculture system in brackish water

Integrated Multi-Trophic Aquaculture takes advantage of the mutualism between some detritivorous fish and phytoplankton. The fish recycle nutrients by consuming live (and dead) algae and provide the inorganic carbon to fuel the growth of live algae. In the meanwhile, algae purify the water and generate the oxygen required by fishes. Such mechanism stabilizes the functioning of an artificially recycling ecosystem, as exemplified by combining the euryhaline tilapia Sarotherodon melanotheron heudelotii and the unicellular alga Chlorella sp. Feed addition in this ecosystem results in faster fish growth but also in an increase in phytoplankton biomass, which must be limited. In the prototype described here, the algal population control is exerted by herbivorous zooplankton growing in a separate pond connected in parallel to the fish-algae ecosystem. The zooplankton production is then consumed by tilapia, particularly by the fry and juveniles, when water is returned to the main circuit. Chlorella sp. and Brachionus plicatilis are two planktonic species that have spontaneously colonized the brackish water of the prototype, which was set-up in Senegal along the Atlantic Ocean shoreline. In our system, water was entirely recycled and only evaporation was compensated (1.5% volume/day). Sediment, which accumulated in the zooplankton pond, was the only trophic cul-de-sac. The system was temporarily destabilized following an accidental rotifer invasion in the main circuit. This caused Chlorella disappearance and replacement by opportunist algae, not consumed by Brachionus. Following the entire consumption of the Brachionus population by tilapias, Chlorella predominated again. Our artificial ecosystem combining S. m. heudelotii, Chlorella and B. plicatilis thus appeared to be resilient. This farming system was operated over one year with a fish productivity of 1.85 kg/m 2 per year during the cold season
