“…Neritina tuberculata, Melanoides tuberculata). Fish and shrimp juveniles that depend on zooplankton during their early life stages in coastal waters (Choudhury, 1971a,b;Cutolo de Araujo and Valenti, 2007) showed the most enriched δ 13 C values. Secondary consumers had intermediate δ 13 C values that related the integration of various carbon sources via the assimilation of consumers.…”

This paper determines the bioaccumulation and transfer processes of organochlorine pesticides within the stream food web in Guadeloupe (Caribbean). ABSTRACTConcentrations of organochlorine pesticides and stable isotope ratios of nitrogen and carbon were measured in a tropical freshwater ecosystem to evaluate the contamination level of biota and examine the bioaccumulation patterns of pollutants through the food web. Chemical analyses showed a general and heavy contamination of the entire food web. They revealed the strong accumulation of pollutants by juveniles of diadromous fishes and shrimps, as they re-enter the river. The role of ecological factors in the bioaccumulation of pesticides was evaluated. Whereas the most persistent pollutants (chlordecone and monohydro-chlordecone) were related to the organisms diet and habitat, bioaccumulation of β-HCH was only influenced by animal lipid content. The biomagnification potential of chlordecone through the food chain has been demonstrated. It highlighted the importance of trophic transfer in this compound bioaccumulation process. In contrast, bioconcentration by passive diffusion from water seemed to be the main exposure route of biota to β-HCH.

“…In populations living in coastal rivers and adjacent estuaries, the larvae require for successful development a low or moderate salt concentration (Guest & Durocher 1979, Lobão et al 1987, Rojas et al 1990, Araujo & Valenti 2007. As a consequence of this physiological constraint, riverine populations living near the coast must follow an 'export strategy' (Strathmann 1982), which includes early larval transport to estuarine or coastal marine habitats and subsequent development in brackish or marine waters (Odinetz Collart 1991a).…”

During downstream transport from rivers to estuaries, early larval stages of the Amazon River prawn Macrobrachium amazonicum (Heller 1862) are likely exposed to planktonic food limitation. In the laboratory, we studied the effects of presence or absence of food on larval survival, moulting and biomass (dry mass, and content of carbon, hydrogen and nitrogen). Unfed larvae developed successfully from hatching of the Zoea I (Z I) to the third zoeal stage (Z III). Complete absence of starvation effects indicated obligatory lecithotrophy in Z I, while significantly delayed moulting and reduced biomass in unfed Z II proved that this stage is facultatively lecithotrophic. Although unfed Z III did not develop any further (obligatory planktotrophy), they still showed a high endotrophic potential, surviving for up to another 10 d (in total 2 wk from hatching), and utilizing about two-thirds of their initial biomass. Dramatically decreasing C:N ratios in unfed larvae suggest an almost complete metabolic degradation of internal lipid stores (visible as fat droplets in the hepatopancreas region), but little protein mobilization. Larvae obtained from 2 different females differed significantly in biomass at hatching and, correspondingly, also in maximum survival time, delay of moulting to the Z III and average rates of biomass utilization. In conclusion, the early larval stages of M. amazonicum depend very little on food, shifting from completely non-feeding behaviour (Z I) through facultative lecithotrophy (Z II), to planktotrophy (later stages). This ontogenetic pattern may be an adaptation to initial food limitation associated with larval export from limnic to estuarine environments.

“…amazonicum, which is commonly referred to as "Amazon River prawn", can grow to large body size (up to about 16 cm total length or 30 g fresh weight) and is therefore considered as a candidate for commercial aquaculture (New, 2005;Moraes-Valenti & Valenti, 2010;Hayd et al, 2010Hayd et al, , 2014. Optimum physical conditions for larval rearing have been found at salinities 10-15 (Guest & Durocher, 1979;Barreto & Soares, 1982;Araujo & Valenti, 2007). Our experiments show, however, that successful development from hatching to the first juvenile stage is possible also at salinity 5.…”

“…Development from hatching to early juvenile stages of M. amazonicum is possible at oligohaline conditions (salinities 1-5), but maximum survival has been observed at higher salinities (10-16; Guest & Durocher, 1979;Barreto & Soares, 1982;Araujo & Valenti, 2007). Besides total salt concentration, also the ionic composition of the culture water is important for physiological functions such as respiration, excretion, and osmoregulation, especially at low salinities (Roy et al, 2007).…”

ABSTRACT. In the aquaculture of prawns in inland facilities, the supply with natural seawater is technically difficult and expensive, while the use of artificial salt may be suboptimal due to unfavorable ionic composition. In the present study, Amazon River prawn, Macrobrachium amazonicum, were reared from hatching through nine larval stages to the first juvenile instar, comparing four experimental conditions with two salinities (5, 10) and two different types of salt (artificial, natural). Larval biomass growth was measured in terms of changes in dry weight (W), contents of carbon and nitrogen (C, N), and proximate biochemical composition (lipid, protein); moreover, body size (carapace length, CL) was measured in first-stage juveniles. After passing through the nonfeeding first larval stage, later stages showed an exponential increase in values of biomass per individual. Rates of increase differed significantly among treatments, showing generally lower growth in experiments with artificial vs. natural salt, and at 5 vs. 10. The same response pattern was found also in CL of early juvenile shrimps. Similar but mostly weaker effects were observed in the percentage C, N, lipid, and protein values (in % of W), and in the C: N mass ratio. Our data indicate that larval rearing of M. amazonicum is feasible with artificial salts and at lower than commonly used standard salinity (10). This makes the cultivation of this species feasible also in aquaculture facilities located at large distance from the coast, where a reduction of costs and logistic investments may compensate for reduced larval growth and production of smaller juveniles. However, these salinity effects on offspring production have to be taken into account in comparisons of growth data from different laboratories and locations.
