“…Detritus therefore seems not to negatively affect the growing rate of survivors. For caprellids cultured under laboratory conditions at small- or medium-scales [ 25 , 26 ] it is therefore recommended that a mixed diet of detritus enriched with Artemia , especially during the first 15 days of culture, is used.…”

“…Colonies of bryozoans and hydroids attached to floating pontoons, buoys and ropes of the marinas were handpicked. Preliminary caprellid sorting was conducted in situ, before the individuals were transported with aeration together with some bryozoan colonies to the laboratory (see [ 25 ]).…”

“…During recent years, several promising results have been obtained by using marine amphipods as alternative prey for fishes [ 21 , 22 ] and cephalopods [ 23 , 24 ] and several amphipod species have recently been cultured under controlled conditions for potential use in aquaculture (e.g. [ 25 ]). [ 4 ] examined aspects of known biology and ecology of caprellid amphipods and their potential suitability as a novel marine finfish feed, concluding that caprellids were worthy of consideration for application in marine finfish aquaculture.…”

“…The suggestion was based on the following characteristics: (i) they have a widespread global distribution, (ii) they form an important natural dietary component in a variety of coastal marine finfish, (iii) they contain high levels of beneficial polyunsaturated fatty acids, (iv) caprellids are relatively sedentary, readily colonise artificial structures (fouling communities) and under appropriate conditions can reach high biomass, especially around fish farms, (v) they exhibit fast growth with several generations per year, (vi) they are opportunistic feeders, (vii) some species show wide environmental tolerances, and (viii) recent studies have indicated the potential suitability of caprellids to larger scale culture (i.e. [ 25 ]).…”

The search for alternative live feed organisms and the progression of Integrative Multi-Trophic Aquaculture (IMTA) are currently being highly prioritised in EU strategies. Caprellids could potentially be an important exploitable resource in aquaculture due to their high levels of beneficial polyunsaturated fatty acids, fast growing nature and widespread distribution. Furthermore, since they are mainly detritivorous, they could be excellent candidates for integration into IMTA systems, potentially benefitting from uneaten feed pellets and faeces released by cultured fish in fish farms and sea-cage structures. Despite this, there is a lack of experimental studies to: (i) test inexpensive diets for caprellids, such as detritus, (ii) develop sustainable caprellid culture techniques and (iii) include caprellids in IMTA systems. The main aim of this study was to determine whether detritus (D) in the form of fish faeces provided an adequate diet for caprellids in comparison to other traditional diets, such as Artemia nauplii (A) or phytoplankton (P). Adult survival rate was shown to be significantly higher for caprellids fed with D. Conversely, hatchlings had the highest survival rate with A, although the juvenile growth rate and number of moults was similar in the three diets. With regard to lipid composition, caprellids fed with A had higher concentrations of Triacylglycerols (TAG) and Phosphatidylcholine (PC) while those fed with P or D were richer in polyunsaturated fatty acids, especially 22:6(n-3) (DHA). Interestingly, caprellids fed with D were also a rich source of 18:2(n-6) (LA), considered to be an essential fatty acid in vertebrates. It was found that detritus based mainly on fish faeces and uneaten feed pellets can be considered an adequate feed for adult caprellids, providing a source of both omega-3 (DHA) and omega-6 (LA) fatty acids. Hatchlings however seem to require an additional input of TAG and PC during juvenile stages to properly grow.
