“…The same procedure was also undertaken with 300 G. pulex. Bloor et al [3] previously showed that in a deionised water test media (without aeration) both G. pulex and A. aquaticus could survive for several weeks without mortalities.…”

“…Over the years, scientists have used a variety of nutritional supplements to feed macroinvertebrates during breeding programmes and experiments, including dog food [1], baby, and fish food [2]. If the macroinvertebrates were being bred for ecotoxicological studies (or as test subjects within bioassays) they need to be representative of wild specimens, and it is well documented that a test, animals response could be affected by their past history, diet, life stage, disease and so forth [3,4]. Therefore, by feeding the animals with an unnatural diet, which may not contain the appropriate nutritional requirements, they could display a false negative/positive response during a test.…”

An investigation was undertaken to establish if Gammarus pulex and Asellus aquaticus preferred a diet of unconditioned, artificially or naturally conditioned alder leaves (Alnus glutinosa). Standardised, 24 hour ex situ feeding assays were undertaken with both species to determine their food preference. The results showed that A. aquaticus ate more leaf material compared to G. pulex (Z 23.909, P 0.001) when exposed to all three test variables. Also, both G. pulex and A. aquaticus demonstrated a preference for naturally conditioned leaves compared to the other two variables, with unconditioned leaves proving the least popular food option for both macroinvertebrates (Z 18.803, P < 0.001). However, both species ate varying amounts of all the leaf treatments (Z 136.399, P < 0.001). Subsequently, the author outlined a feeding methodology for natural alder leaf conditioning that could be used during a laboratory breeding programme.

Gammarus spp. represent an important taxon in running water ecosystems concerning both structural and functional aspects. Gammarus spp. are also part of several macrozoobenthos indices for assessing biological water quality. However, in ecotoxicological water quality assessment, this taxon has been used much less than Daphnia spp. A new user-friendly and low-cost test protocol for Gammarus spp. has been developed, constituting the "ecotoxicological module "of an integrated multimetric triad-based concept for water quality assessment. The GamTox test is based on several test parameters: behavior (especially locomotion and feeding) depicts rapid and sensitive early warning indicators, survival displays an indicator of severe acute stress, and biochemical biomarkers, esp. AChE inhibition, is a sensitive marker of neurotoxic xenobiotic stress. GamTox can be performed both in situ and ex situ, based either on visual or automatical recording.

“…As a detritus feeder, G. pulex plays a key role in nutrient cycling in freshwater systems (Welton, 1979) and Gammarus species are among the most eaten prey for many fish species (Bollache et al, 2006). G. pulex is known to be sensitive to a wide range of pollutants and to be among the most sensitive aquatic invertebrates (Helson & Surgeoner, 1986;Mian & Mulla, 1992;Wogram & Liess, 2001;Cold & Forbes, 2004;Van Wijngaarden et al, 2004;Bloor et al, 2005). This amphipod species can be easily grown in the laboratory and has been recommended for use in toxicity tests (McCahon & Pascoe, 1988a, b;Adam et al, 2010).…”
