“…These differences may be explained by differences in the life history of the two amphipod species. E. marinus is a marine amphipod that lives in the intertidal zone in association with species of algae that are used as both habitat and food source (Martins, Leite and Constantino, 2014). Strong positive thigmotaxis and negative phototaxis behaviours would keep organisms in association with the algae during circatidal rhythms and strong currents.…”

“…The Fucus diet was supplied exclusively to E. marinus, as it is suggested as the (strongly) preferred diet (Martins et al 2014); all other diets were fed to both G. locusta and E. marinus. The carrot leaves and thalli of Ulva and Fucus were rinsed with fresh water and dried at 50°C for 10 h. The lupin diet consisted of lupin meal mixed with water, shaped into pellets and dried at 50°C for 16 h.…”

“…Even though this species can express predatory behaviour (Dick et al 2005, Alexander et al 2013, it shows strong preferences for Fucus spp. in its herbivorous diet (Martins et al 2014). Life in harsh intertidal habitats may also be corroborated by a prolonged brood care strategy, which is indicated by much higher sizes at hatching.…”

Rapidly expanding fed aquaculture demands high-quality, sustainable nutrient sources for utilisation as dietary ingredients. Exploring the potential of under-utilised resources from other industries is imperative to replace finite natural resources, such as fish meal. Marine gammarids may be an excellent source of essential fatty acids; however, their aquaculture using formulated diets remains untested in terms of survival, growth and nutritional value of the cultured product. Here, juveniles of 2 marine gammarid species, Gammarus locusta and Echinogammarus marinus, were maintained in controlled feeding experiments with 2 marine diets (Ulva spp. and Fucus spp.) and 2 terrestrial diets (lupin meal and carrot leaves). G. locusta exhibited higher survival rates, particularly when fed carrot leaves, an agricultural waste product. Fatty acid profiles of the resulting G. locusta product appear well suited for marine finfish nutrition, indicating high suitability of G. locusta as an aquaculture diet source. In contrast, whilst E. marinus may provide beneficial fatty acid profiles for aquatic animal nutrition, its poor growth performance in this study indicates that further dietary/culture research is required for this species. Our results indicate, for the first time, that marine gammarids are capable of trophic upgrading and can use nonmarine diets for healthy growth in culture, but their suitability as a formulated feed ingredient for specific fish or crustacean species needs to be investigated individually. Future research should include the development of optimal large-scale production as well as investigation of optimal methods of inclusion of gammarids as feed ingredient for target aquaculture species.

“…The overall consumption rate of E. marinus in the present study was markedly higher than previously recorded for the species. For example, Martins et al (2014) recorded an average consumption of fresh F. vesiculous of 0.29 g per g body mass per day in winter. In comparison, when similarly mass adjusting the daily consumption values for the present experiment using the overall mean consumption divided by the amphipods' mean final weigh, the average food consumption was 0.86 g per g body weight.…”

“…The intertidal amphipod Echinogammarus marinus was chosen as a model species due to its estuarine habitat being at particular risk of plastic pollution (Gallagher et al, 2016;Lima et al, 2014;Mathalon & Hill, 2014), as well as for its central position in the food web, both as predator (Dick et al, 2005) and prey (Múrias et al, 1996). Recent evidence suggest that microplastics can adhere to the mucus of Fucus vesiculosus (Gutow et al, 2015), a favoured seaweed for E. marinus (Martins et al, 2014). This may thus represent an important exposure pathway.…”

Chronic ingestion of polystyrene microparticles in low doses has no effect on food consumption and growth to the intertidal amphipod Echinogammarus marinus?

The ingestion of microplastics (plastic particles <5 mm) has been observed in a range of marine organisms, and adverse effects have been reported in several species after high concentration exposure. However, the long-term effects of low-dose ingestion remains unclear. The aim of this study was thus to assess the chronic effects of low concentrations of polystyrene microparticles to the intertidal amphipod Echinogammarus marinus, using food consumption, growth, and moulting as endpoints. Amphipods were fed a gelatinous algal feed spiked with microbeads (8 μm) in concentrations of ∼0.9, 9 and 99 microplastics/g for 35 days. E. marinus was also analysed for retention of microplastics, and egestion rate was calculated in a separate high-dose feeding experiment. No significant effects were found in the food consumption or growth assays. There was no accumulation of microplastics in the gut, with only one microbead recorded internally in three (8%) of the exposed amphipods. The low number is likely linked to gastrointestinal functions, allowing for easy egestion of indigestible items. This assumption was supported by the observation that after high-dose exposure, 60% of E. marinus egested all microbeads within 24 h. This study suggests that ingesting low concentrations of 8 μm microplastics do not impair the feeding or growth of amphipods along the exposure period. We hope that negative results such as these may further assist in assessing the impact posed by microplastics to marine organisms.
