“…When the shrimp Palaemonetes argentinus is infected by the branchial ectoparasite isopod Probopyrus ringueleti and starved for 15 days, a decline in lipid concentrations and preferential carbohydrates utilization was detected (Neves et al, 2004). In unparasitized organisms no significant differences were observed on glucose and glycogen concentrations, while total lipids decreased significantly (nearly 66%) in the first 24 h, and remained low until the end of the experiment.…”

“…Other species have a faster rate of lipid depletion, e.g. Penaeus vannamei (Penaeidae) reaches the lowest lipid levels after 4 days of starvation [ 38 ], and Palaemon argentinus uses 66% of the initial lipids during the first day of starvation [ 8 ]. Instead, in our work, Palaemon argentinus utilized ~ 30% of their lipid reserves throughout 3 starvation days.…”

Energy reserves mobilization: Strategies of three decapod species

et al. 2017

In food deprivation assays, several different responses have been observed in crustaceans. However, studying energy reserves utilization among more than one species during the same starvation period has not yet been performed, particularly to discern whether the responses are due to intrinsic and/or environmental factors. We hypothesize that decapod species with similar feeding habits have the same strategies in the use of energetic reserves during starvation, even though they inhabit different environments. The aim of this study was to compare the energy reserves mobilization of three decapods species (Cherax quadricarinatus, Palaemon argentinus and Munida gregaria) with similar feeding habits, exposed to similar food deprivation conditions. The crayfish, shrimp and squat-lobster were experimentally kept at continuous feeding or continuous starvation throughout 15 days. Every 3rd day, the midgut gland index (MGI), and the glycogen, lipid and protein contents were measured in the midgut gland (MG) and pleon muscle. Palaemon argentinus mobilized more reserves during starvation, followed by C. quadricarinatus, and the last M. gregaria. The starved shrimps presented low MGI, whereas MG showed a reduction in glycogen (from day 6 to 15), lipid (from day 3 to 15), and protein levels (at day 9 and 15) while in their muscle, lipid reserves decreased at days 3 and 6. In C. quadricarinatus, the most affected parameters in the MG were MGI, glycogen (from day 6 to 15), and lipids (at day 12 and 15). In the MG of M. gregaria only the glycogen was reduced during fasting from 3 to 15 days. Even though the three studied species have similar feeding habitats, we found that their energetic profile utilization is different and it could be explained by the habitat, life span, temperature, organ/tissue, and metabolism of the species. Our results may be useful to understand the several different responses of crustaceans during starvation.

“…However, documentation on other bopyrids of the same genus shows devastating effects to their respective hosts, such as a reduction of respiratory rate in Palaemonetes argentinus (Nobili, 1901) due to infection with Probopyrus ringueleti (Verdi & Schuldt, 1987) (cf. Anderson, 1975;Schuldt & Rodrigues-Capítulo, 1987;Neves et al, 2000), re-allocation of the host's energetic reserves (Bass & Weis, 1999;Astete-Espinoza & Caceres, 2000;Neves et al, 2004), and sexual sterility (Pike, 1960).…”

A bopyrid isopod was found attached in the gill chamber of a wild giant freshwater prawn, Macrobrachium rosenbergii (De Man, 1879) from the Timun River, Negeri Sembilan (Malaysia) (2 • 28 N 102 • 02 E), with a prevalence of 0.27% (2/743). The specimens measured 18.25 ± 0.35 mm in length and 15.25±0.35 mm in width. The body of the isopod was subcordate and slightly distorted. It has five oostegites, with black pigment. The first oostegites are large, the 2 nd and 3 rd are suboval and smaller, while the 4 th and 5 th are long and ending in sharp points. Both specimens were identified as adult female Probopyrus buitendijki (Horst, 1910). The isopod was found only in January of 2009 and 2010, which months recorded a relatively low rainfall. A histopathological study of the infected gill showed impairment of the gill filaments, necrosis, and hyperplasia. Such effects may reduce the respiration efficiency of the gills. RÉSUMÉUn isopode Bopyridae a été trouvé fixé dans la chambre branchiale de la crevette géante d'eau douce, Macrobrachium rosenbergii (De Man, 1879) de la rivière Timun, Negeri Sembilan (Malaisie) (2 • 28 N 102 • 02 E), avec une prévalence de 0.27% (2/743). L'isopode mesurait 18,25 ± 0,35 mm de long et 15,25 ± 0,35 mm de large. Le corps de l'isopode était subcordiforme et légèrement déformé. Il possède cinq oostégites, avec un pigment noir. Les premières oostégites sont de grande taille, les 2èmes et 3èmes sont de forme subovale et plus petites, tandis que les 4èmes et 5èmes sont longues et terminées en pointes aigües. Les spécimens ont été identifiés comme des femelles adultes de Probopyrus buitendijki (Horst, 1910). L'isopode a été trouvé seulement en janvier 2009 et 2010, mois présentant des précipitations relativement basses. Une étude histopathologique de la branchie infectée s'a révélé une détérioration des filaments branchiaux, une nécrose et une hyperplasie. De tels effets pourraient réduire l'efficacité de la respiration des branchies. 1 )
