“…Sesarma rectum usually feeds on a mixed diet but the diet is composed mainly of mangrove leaves (around 75 %, see STEINKE et al, 1993) and N. granulata feeds on a diet composed of fewer plant matter, showing an opportunist behavior in relation to foods encountered (KUCHARSKI & SILVA, 1991). This study also demonstrated for the first time the effects of known feeding stimulants, such as betaine or cadaverine (see COMAN et al, 1996) in the intake patterns of crabs, an understudied group of crustaceans in relation to non-natural food sources.…”

ABSTRACT. Calcium (Ca) is essential for crustaceans, due to calcium carbonate (CaCO 3 ) deposition in the new exoskeleton to harden it. The purpose of this work was to study short term Ca balance in terms of dietary Ca ingestion in two phylogenetically related crabs (Superfamily Grapsoidea) showing different degrees of terrestrial adaptations: Sesarma rectum Randall, 1840 and Neohelice granulata (Dana, 1851). Dietary Ca ingestion was studied using purified diets with different Ca concentrations (0, 2.2 and 6.66 % Ca), together with measurements of Ca excretion and Ca hemolymph levels. The results showed that both crabs had the same response to foods containing different levels of Ca, with both species eating more of the high Ca diet. However, S. rectum consumed more per mg body mass at all Ca concentrations (6 mg.g -1 for S. rectum against 3 mg.g -1 for N. granulata). Both species excreted/egested Ca differently: S. rectum excreted Ca proportionally to ingestion, whereas N. granulata maintained constant faecal Ca output at all dietary Ca levels. Moreover, Ca hemolymph levels for crabs fed the different diets were independent of dietary Ca. In conclusion, both S. rectum and N. granulata seem to regulate the consumption of diets containing more Ca, which suggests a fine balance for Ca intake.KEYWORDS.

A importância do consumo de cálcio na dieta de duas espécies de caranguejos grapsóides semi-terrestres.O cálcio (Ca) é essencial para os crustáceos porque cristais de carbonato de cálcio (CaCO 3 ) são depositados no novo exoesqueleto para endurecê-lo. O objetivo do presente trabalho foi estudar o balanço do Ca em relação à sua ingestão em dois caranguejos filogenéticamente relacionados (Superfamília Grapsoidea), que apresentam diferentes graus de terrestrialidade: Sesarma rectum Randall, 1840 e Neohelice granulata (Dana, 1851). A ingestão de Ca foi estudada através do uso de dietas purificadas com diferentes quantidades de Ca (0, 2,2 e 6,66 % Ca), juntamente com a excreção de Ca nas fezes e níveis de Ca na hemolinfa. Os resultados mostraram que ambos apresentam a mesma resposta em relação aos níveis de Ca na dieta, ingerindo mais da dieta com maior quantidade de Ca. Sesarma rectum, porem, consumiu mais dieta por mg de peso para todas as concentrações de Ca utilizadas (6 mg.g -1 para S. rectum contra 3 mg.g -1 para N. granulata). As duas espécies excretaram Ca de maneira diferente: S. rectum excretou em proporção direta à quantidade ingerida, enquanto N. granulata manteve constante a excreção de Ca independente do Ca ingerido. Níveis de Ca na hemolinfa, por outro lado, foram iguais e independentes da quantidade de Ca ingerido para os dois caranguejos. Desse modo, tanto S. rectum como N. granulata parecem discriminar e ingerir dietas com maior quantidade de Ca, sugerindo uma regulação fina na ingestão do Ca.

“…To enhance the results obtained in this study or to evaluate higher levels of fishmeal replacement for SPC, new formulations that include ingredients that increase the feed attractiveness are recommended, such as squid meal, krill meal (Sáchez et al, 2012), synthetic amino acids, such as methionine, lysine and/or threonine (Sookying et al, 2013), or taurine, free amino acids, non-essential amino acids, and food stimulants recommended for better growth performance of fish and shrimp (Coman et al, 1996;Martinez et al, 2004). Irrespective of fishmeal replacement level, shrimp in the present study exhibited the same apparent feed efficiency, demonstrating their ability to absorb nutrients from SPC.…”

-This study aimed to assess the final body weight, weekly weight gain, yield, apparent feed efficiency, protein efficiency ratio, and feed intake of the Pacific white shrimp (Litopenaeus vannamei) fed four diets containing different levels of soy protein concentrate (SPC) as a replacement for fishmeal, reared in a super-intensive biofloc system. Diets consisted of replacing 209 g kg −1 fishmeal at 0, 33, 66, and 100% SPC. Shrimp were raised in a biofloc system using twelve experimental units stocked with 250 shrimp m −3 under constant aeration (O2>5mg L −1 ) and temperature (29±0.5 °C). No significant differences among treatments were observed based on water quality parameters. Shrimp fed diets with 0 and 33% substitution exhibited the highest weekly growth (1.88 and 1.79 g per week) and final weights (15.2 and 14.7 g) compared with shrimp fed the 66 and 100% replacement. A lower feed intake was observed for shrimp fed the 33% SPC diet (3.18 kg per experimental unit) compared with 0% replacement (3.62 kg). Shrimp fed the 33% replacement achieved a similar performance and lower feed intake than animals fed diet without replacement.

“…Amino acids are abundant in tissues of marine and freshwater invertebrates (Sutcliffe, 1962;Firling, 1977;Edwards, 1982;Herzog and Liappis, 1987;Carr et al, 1996;Zimmer et al, 1999), and they act as feeding stimulants/ attractants for diverse predatory species (Carter and Steele, 1982;Carr, 1988;Valentincic and Captrio, 1994;Coman et al, 1996;Hara, 2006;Keiichiro et al, 2006). In the present study, worm (Eisenia rosea Gates 1942) prey of adult newts (Taricha torosa Rathke 1883) were collected on three occasions (April 14, August 26 and October 12, 2004) from natural streamside sediments at the field study site.…”

SUMMARY Chemoreception may function throughout an entire animal lifetime, with independent, stage-specific selection pressures leading to changes in physiological properties, behavioral expression, and hence, trophic interactions. When the California newt (Taricha torosa) metamorphoses from an entirely aquatic larva to a semi-terrestrial juvenile/adult form, its chemosensory organs undergo dramatic reorganization. The relationship between newt life-history stage and chemosensory-mediated behavior was established by comparing responses of adults (as determined here) to those of conspecific larvae (as studied previously). Bioassays were performed in mountain streams,testing responses of free-ranging adults to 13 individual l-amino acids. Relative to stream water (controls), adults turned immediately upcurrent and moved to the source of arginine, glycine or alanine release. These responses were indicative of predatory search. Arginine was the strongest attractant tested, with a response threshold (median effective dose)of 8.3×10–7 mol l–1 (uncorrected for dilution associated with chemical release and delivery). In contrast to adult behavior, arginine suppressed cannibal-avoidance and failed to evoke search reactions in larvae. For a common set of arginine analogs, the magnitudes of adult attraction and larval suppression were not positively correlated. Suppression of cannibal-avoidance behavior in larvae was unaffected by most structural modifications of the arginine molecule. Adult behavior, on the other hand, was strongly influenced by even subtle alterations in the parent compound. Reactions to arginine in both adults and larvae were eliminated by blocking the external openings of the nasal cavity. Stimulating adult predatory search in one case and inhibiting larval cannibal avoidance in the other, arginine is a chemical signal with opposing behavioral effects and varying ecological consequences. Significant differences between responses of adults and larvae to changes in arginine structure suggest alternative, chemosensory receptor targets. Although arginine reception functions throughout an entire newt lifetime, an ontogenetic shift in larval and adult chemoreceptive ability changes behavioral expression, and thus, reflects the unique selection pressures that act at each life-history stage.
