“…It is known that the growth of the marine decapod Penaeus monodon (which feeds primarily on phytoplankton and animal carrion) is positively correlated with the diet's content of the EAA arginine, histidine, leucine, isoleucine, phenylalanine and tryptophane [27], [39]. For the growth of the related species Parapenaeus longirostris , not only arginine, but also histidine was found to be particularly important [28]. Here, we did not find any evidence for a growth-promoting effect of a single EAA on D. pulex .…”

“…For Daphnia , the same amino acids are considered to be essential as for insects and mammals [25] , and the pool of free amino acids in D. magna is dominated by histidine, arginine, alanine, and glutamate [26] . Among those, the two essential amino acids arginine and histidine were shown to be particularly important for growth of marine decapods [27] , [28] . Therefore, we hypothesized that the availability of dietary EAA in general and arginine and histidine specifically, would affect both the choice of reproductive strategy in Daphnia , and also the somatic growth of this herbivorous zooplankton.…”

Dietary Essential Amino Acids Affect the Reproduction of the Keystone Herbivore Daphnia pulex

Recent studies have indicated that nitrogen availability can be an important determinant of primary production in freshwater lakes and that herbivore growth can be limited by low dietary nitrogen availability. Furthermore, a lack of specific essential nitrogenous biochemicals (such as essential amino acids) might be another important constraint on the fitness of consumers. This might be of particular importance for cladoceran zooplankton, which can switch between two alternative reproductive strategies – the production of subitaneously developing and resting eggs. Here, we hypothesize that both the somatic growth and the type of reproduction of the aquatic keystone herbivore Daphnia is limited by the availability of specific essential amino acids in the diet. In laboratory experiments, we investigated this hypothesis by feeding a high quality phytoplankton organism (Cryptomonas) and a green alga of moderate nutritional quality (Chlamydomonas) to a clone of Daphnia pulex with and without the addition of essential amino acids. The somatic growth of D. pulex differed between the algae of different nutritional quality, but not dependent on the addition of dissolved amino acids. However, in reproduction experiments, where moderate crowding conditions at saturating food quantities were applied, addition of the essential amino acids arginine and histidine (but not lysine and threonine) increased the total number and the developmental stage of subitaneous eggs. While D. pulex did not produce resting eggs on Cryptomonas, relatively high numbers of resting eggs were released on Chlamydomonas. When arginine and histidine were added to the green algal diet, the production of resting eggs was effectively suppressed. This demonstrates the high, but previously overlooked importance of single essential amino acids for the reproductive strategy of the aquatic keystone herbivore Daphnia.

“…Several amino acids are known to be involved in moulting related processes [35], through multiple ways. For instance, branched chain amino acids (leucine, isoleucine and valine) are involved in muscle growth [36], as well as in haemocyanin synthesis and transportation [37], lysine is related to the production of elastin and collagen [38] and to the absorption of calcium for exoskeleton formation [39], phenylalanine and tyrosine are involved in the synthesis of the pigment melanin and in haemocyanin transportation processes [40], while glutamine is involved in muscle growth [41].Asinother crustaceans, growth and moult are tightly correlated in terrestrial isopods and dependent on the frequent replacement of their cuticle [39]. Although moulting is not considered the main excretion route of metals in these organisms [42], it has been reported to take part on this process.…”

This work aimed at characterizing the metabolome of the isopod Porcellionides pruinosus and at assessing its variations over 14 days under laboratory culture conditions and upon exposure to the contaminant metal Nickel (Ni). The spectral profiles obtained by 1 H NMR spectroscopy were thoroughly assigned and subjected to multivariate analysis in order to highlight consistent changes. Over 50 metabolites could be identified, providing considerable new knowledge on the metabolome of these model organisms. Several metabolites changed non-linearly with Ni dose and exposure time, showing distinct variation patterns for initial (4 days) and later time points (7 and 14 days). In particular, at day 4, several amino acids were increased and sugars were decreased (compared to controls), whereas these variations were inverted for longer exposure, possibly reflecting earlier and more intensive moulting. Other variations, namely in betaines and choline-containing compounds, were suggested to relate with osmoregulation and detoxification mechanisms. Ni also had a marked effect on several nucleotides (increased upon exposure) and a moderate impact on lipids (decreased upon exposure). Overall, this study has provided new information on the Ni-induced metabolic adaptations of the P. pruinosus isopod, paving the way for improved mechanistic understanding of how these model organisms handle soil contamination.Significance: This study provided, for the first time to our knowledge, a detailed picture of the NMR-detectable metabolome of terrestrial isopods and of its fluctuations in time and upon exposure to the contaminant metal Nickel. Several time-and dose-dependent changes were highlighted, providing mechanistic insight into how these important model organisms handle Ni contamination.

“…Finally, in both shrimp and lobster species, the limiting amino acid is methionine [101]. Variations in amino acids that cannot be synthesized de novo (EAA) reflect the dietary condition [10], and deficiencies or excesses of one or more EAA limit protein synthesis, growth or both [102][103][104]. Amino acid deficiencies provoke low survival of Pacifastacus leniusculus juveniles after 100 days of culture [105].…”

Ontogenetic changes in energetic reserves, digestive enzymes, amino acid and energy content of Lithodes santolla (Anomura: Lithodidae): Baseline for culture

The southern king crab (SKC) Lithodes santolla is an important commercial species in southern South America. Fishing pressure has caused the deterioration of its stocks. Currently, culture techniques are being developed for producing SKC juveniles to enhance the natural population and to recover the fishing stock. Therefore, it is necessary to know about physiology, energetic and nutritional requirements for SKC maintenance in hatchery. Thus, this study aims to evaluate the biochemical and physiological changes in the midgut gland, muscle and hemolymph of juveniles, pre-adults and adults of wild SKC. The energetic reserves, digestive enzymes activity, amino acid profile and energy were quantified in twelve juveniles, ten pre-adult, and ten adult crabs. Juveniles showed high glycogen and low lipids in the midgut gland, and low proteins and low lactate in muscle. In the hemolymph, juveniles had high lipids. Pre-adults had high glycogen and lipids in the midgut gland, and both high protein and lactate in muscle. In the hemolymph, pre-adults had high lipids. Adults had low glycogen and high lipids in midgut gland, and both high proteins and high lactate in muscle. In hemolymph, adults had high glucose and lactate. Juveniles and pre-adults had high proteinase activity, whereas adults had high lipase activity. Major essential amino acids of SKC were arginine, methionine, and tryptophan, and the non-essential amino acids were glycine, aspartic acid and glutamic acid. On another hand, SKC had similar energy in the midgut gland and muscle, regardless of the ontogenetic stage. Moreover, we demonstrated that the biochemical energy calculation underestimates the actual measured values by a calorimeter. Thus, our results help to understand the physiological changes, energetic and nutritional requirements of L. santolla, and this study is a baseline for research on diet formulation for maintaining this species under culture conditions.
