“…The conclusion that taste preferences remain stable in fishes stimulated by food odour was supported by a later study in two cyprinid fishes, C. carpio and R. rutilus (Kasumyan & Marusov, ). Agar pellets containing glycine, L‐proline or L‐alanine (0.1 M for all) were simultaneously given to isolated individuals in clean water or in the presence of food odour (chironomid larvae water extract).…”

“…This indicated that the demand for taste quality of food becomes higher in fishes agitated by attractive food odour. Undoubtedly, the adaptive significance of such behaviour is related to enhancement of food selection; i.e ., searching and accepting food items with a highly preferred odour of common and palatable food and refusing items with poor or plain taste (Kasumyan & Marusov, ). It follows that this will also decrease the risk of consuming inadequate or harmful food items.…”

“…A study performed on C. carpio showed that fish frightened by alarm pheromone (conspecific skin‐water extract, 10 −3 g l −1 ) grasped pellets with amino acids (glycine or L‐proline; 0.1 M for both) several times less often than in clean water and rejected most of them. However, changes in pellet acceptance ratio between intact fish and in fish stressed by alarm pheromone have not been found (Kasumyan & Marusov, ). This indicates stability of taste preferences in fish motivated by available and attractive food, or frightened by a predator.…”

The adaptability of the taste system in fish has led to a large variety in taste bud morphology, abundance and distribution, as well as in taste physiology characteristics in closely related species with different modes of life and feeding ecology. However, the modifications evoked in the sense of taste, or gustation, particularly during ontogeny when fishes are subject to different environmental variables, remain poorly studied. This review paper focusses on current knowledge to show how plastic and resistant the taste system in fishes is to various external factors, linked to other sensory inputs and shifts in physiological state of individuals. Ambient water temperature is fundamental to many aspects of fish biology and taste preferences are stable to many substances, however, the taste‐cell turnover rate strongly depends on water temperature. Taste preferences are stable within water salinity, which gives rise to the possibility that the taste system in anadromous and catadromous fishes will only change minimally after their migration to a new environment. Food‐taste selectivity is linked to fish diet and to individual feeding experience as well as the motivation to feed evoked by attractive (water extracts of food) and repellent (alarm pheromone) odours. In contrast, starvation leads to loss of aversion to many deterrent substances, which explains the consumption by starving fishes of new objects, previously refused or just occasionally consumed. Food hardness can significantly modify the final feeding decision to swallow or to reject a grasped and highly palatable food item. Heavy metals, detergents, aromatic hydrocarbons and other water contaminants have the strongest and quickest negative effects on structure and function of taste system in fish and depress taste perception and ability of fishes to respond adequately to taste stimuli after short exposures. Owing to phenotypic plasticity, the taste system can proliferate and partially restore the ability of fishes to respond to food odour after a complete loss of olfaction. In general, the taste system, especially its functionality, is regarded as stable over the life of a fish despite any alteration in their environment and such resistance is vital for maintaining physiological homeostasis.

“…The high levels of glycine and alanine are of special interest for fish feeding, because these amino acids are feed intake stimulators (Shamushaki et al 2007). Kasumyan and Mikhailova (2014) and Kasumyan and Marusov (2015) showed an increase in the fish's feed intake with alanine and glycine, respectively. Regarding essential amino acids, amphipods have higher levels of isoleucine and valine, but lower of leucine (Table 7).…”

Coastal protection, nutrient cycling, erosion control, water purification, and carbon sequestration are ecosystem services provided by salt marshes. Additionally, salt ponds offer coastal breeding and a nursery habitat for fishes and they provide abundant invertebrates, such as amphipods, which are potentially useful as a resource in aquaculture. Fishmeal and fish oil are necessary food resources to support aquaculture of carnivorous species due to their omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA). Currently, aquaculture depends on limited fisheries and feed with elevated n-3 LC-PUFA levels, but the development of more sustainable food sources is necessary. Amphipods appear to be a potential high quality alternative feed resource for aquaculture. Hence, a nutritional study was carried out for several main amphipod species-Microdeutopus gryllotalpa, Monocorophium acherusicum, Gammarus insensibilis, Melita palmata and Cymadusa filosa-in terrestrial ponds in the South of Spain. These species showed high protein content (up to 40%), high n-3 PUFA and phospholipid levels, and high levels of phophatidylcholine (PC), phosphatidylethanolamine (PE) and triacylglycerols (TAG), the latter being significantly high for M. acherusicum. M. gryllotalpa and M. acherusicum showed the highest proportion of lipids (19.15% and 18.35%, respectively). Isoleucine, glycine and alanine were the dominant amino acids in all species. In addition, amphipods collected from ponds showed low levels of heavy metals. Furthermore, the biochemical profiles of the five species of amphipods have been compared with other studied alternative prey. Therefore, pond amphipods are good candidates to be used as feed, and are proposed as a new sustainable economic resource to be used in aquaculture. G. insensibilis may be the best for intensive culture as an alternative feed resource because it shows: 1) adequate n-3 PUFA and PL composition; 2) high levels of glycine,

“…The high levels of glycine and 340 alanine in PNBC amphipods have special interest for fish feeding, taking into account the role of 341 these AA as feed intake stimulators (Shamushaki et al 2007). In two experiments about taste and 342 preference feed, they prove that alanine and valine, in first experiment (Kasumyan and 343 Mikhailova, 2014), and glycine, in the second (Kasumyan and Marusov (2015), increase the 344 fish's feed intake. Regarding essential amino acids, amphipods have higher levels of isoleucine 345 and valine, but lower of leucine (Table 7).…”

Coastal protection, nutrient cycling, erosion control, water purification, and carbon sequestration are ecosystem services provided by salt marshes. Additionally, the salt ponds offers coastal breeding and nursery habitat to fishes and invertebrates providing abundant amphipods potentially useful as a resource in aquaculture. Fishmeal and fish oil are necessary food resources to support aquaculture of carnivorous species due to their omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA). Their dependence on limited fisheries constrains growth of aquaculture and the need for n-3 LC-PUFA recommends the development of more sustainable food sources. Due to their extensive feeding on detritus and primary producers, amphipods appear as potential and high quality alternative feed resource for aquaculture. Hence, a nutritional study was carried out for main amphipods species -Microdeutopus gryllotalpa, Monocorophium acherusicum, Gammarus insensibilis, Melita palmata and Cymadusa filosa-at South Spain aquaculture terrestrial ponds . These species showed a high protein content (up to 40%), high n-3 PUFA and phospholipid levels, and high levels of phophatidylcholine (PC), phosphatidylethanolamine (PE) and triacylglycerols(TAG), the latter significantly high for M. acherusicum . M. gryllotalpa and M. acherusicum showed the highest proportion of lipids (19.15% and 18.35%, respectively). Isoleucine, glycine and alanine were the dominant amino acids in all species. In addition, amphipods collected from ponds showed low levels of heavy metals. Furthermore, the biochemical profile of the five amphipods have been compared with other studied alternatives preys. Therefore, amphipods of ponds are good candidates to be used as feed, and are proposed as a new sustainable economic resource to use in aquaculture. G. insensibilis may be the best to be intensively cultured as an alternative feed resource because shows: 1) adequate PUFAS n-3 and PL composition;2) high levels of glycine, alanine, tyrosine, isoleucine and lysine; 3) high natural densities;PeerJ Preprints | https://doi.org/10.7287/peerj.preprints.3220v1 | CC BY 4.0 Open Access | rec: 2 Sep 2017, publ: 2 Sep 2017 4) large body size ( ≥ 1 cm) and 5) high concentration of Calcium. Moreover, a combined culture of amphipods and fishes in these marsh ponds seems a promising and environmentally sustainable way to develop Integrate Multi-Trophic Aquaculture (IMTA) in these ecosystems.1 Crustacean amphipods from marsh ponds: a nutritious feed resource with potential 2 application in Integrated Multi-Trophic Aquaculture.3 Pablo Jiménez-Prada 1,2* , Ismael Hachero-Cruzado 2 , Inmaculada Giraldez 3 , Catalina Fernández-4 Díaz 2 , César Vilas 2 , José P.
