“…Confirming the existence of this pathway, experimental and field evidence has been presented for ingestion and assimilation of vascular plant detritus by zooplankton (Roman & Rublee 1981, Roman 1984, DeMott 1988, Stoner & Zimmerman 1988, Posch & Arndt 1996, McKinnon & Klumpp 1998 and juvenile decapod crustaceans (Rodelli et al 1984, Loneragan et al 1997, Fantle et al 1999, Dittel et al 2000, Schwamborn & Criales 2000, although for most organisms studied, live food was more important than detritus.…”

“…Stomach content analysis and relatively enriched somatic isotopic values indicate that adult shrimp shift their feeding habits from omnivory to more pronounced carnivorous habits as shrimps migrate from the estuarine environments to the open sea (Schwamborn and Criales 2000). In a study conducted on open sea shrimp, Moncreiff and Sullivan (2001) reported isotopically enriched ␦ 13 C VPDB and ␦ 15 N AIR values for shrimp species caught in the Gulf of Mexico (Farfantepenaeus aztecus: ␦ 13 C VPDB = -17.7‰ and ␦ 15 N AIR = 11.0‰; Farfantepenaeus duorarum: ␦ 13 C VPDB = -16.5‰ and ␦ 15 N AIR = 11.2‰; Litopenaeus setiferus: ␦ 13 C VPDB = -19.6‰ and ␦ 15 N AIR = 11.4‰).…”

Carbon and nitrogen stable isotope values were determined in Pacific white shrimp (Litopenaeus vannamei) with the objective of discriminating animals produced through aquaculture practices from those extracted from the wild. Farmed animals were collected at semi-intensive shrimp farms in Mexico and Ecuador. Fisheries-derived shrimps were caught in different fishing areas representing two estuarine systems and four open sea locations in Mexico and Ecuador. Carbon and nitrogen stable isotope values (␦ 13 C VPDB and ␦ 15 N AIR ) allowed clear differentiation of wild from farmed animals. ␦ 13 C VPDB and ␦ 15 N AIR values in shrimps collected in the open sea were isotopically enriched (−16.99‰ and 11.57‰), indicating that these organisms belong to higher trophic levels than farmed animals. ␦ 13 C VPDB and ␦ 15 N AIR values of farmed animals (−19.72‰ and 7.85‰, respectively) partially overlapped with values measured in animals collected in estuaries (−18.46‰ and 5.38‰, respectively). Canonical discriminant analysis showed that when used separately and in conjunction, ␦ 13 C VPDB and ␦ 15 N AIR values were powerful discriminatory variables and demonstrate the viability of isotopic evaluations to distinguish wild-caught shrimps from aquaculture shrimps. Methodological improvements will define a verification tool to support shrimp traceability protocols.

“…This occurred at the highest detritus and lowest diatom concentration, hinting at a possible impact of detritus abundance on detritus ingestion. The concept of detritus being ingested at extreme detritus concentrations only has been suggested earlier, in a study on feeding strategies of juvenile shrimp in a segrass ecosystem (Schwamborn & Criales, 2000). Only in experiment E2, detritus ingestion was not significant at a = 0.05.…”

Ingestion rates of zoeae of Aratus pisonii Milne Edwards (Brachyura: Grapsidae) were determined offering natural plankton-detritus mixtures in laboratory food selection experiments. The food mixtures were sampled in the Itamaraca´estuary, north-eastern Brazil, and standardised to a size range of 50-200 lm. Zoeae ingested significant amounts of large centric diatoms (Coscinodiscus spp.), mangrove detritus, tintinnids (Favella ehrenbergi) and adult copepods during feeding experiments. Diatoms were positively selected by A. pisonii zoeae in all three experiments, with ingestion rates of 3.3-21.3 cells zoea )1 day )1 . Detritus particles were always more abundant than phytoplankton and zooplankton in the particle size spectrum offered. Detritus was ingested in two of three experiments, with ingestion rates of up to 34.1 particles zoea )1 day )1 , being the most important food item during one experiment. Adult copepods (up to 1.8 ind. zoea )1 day )1 ) and tintinnids (up to 0.4 ind. zoea )1 day )1 ) were ingested by A. pisonii zoeae during one experiment each. In spite of a wide range of zoeal density, food particle composition, and density, zoeae of A. pisonii displayed a consistent pattern of food selectivity. This hints at a consistent sensory and behavioural mechanism related to capture and handling of food particles, that most likely also affects larval feeding under natural conditions. Although detritus showed to be quantitatively ingested under estuarine conditions, zoeae of A. pisonii preferred large diatoms and ingested zooplankton only occasionally.
