“…The current seasonal variations in muscle glycogen content could be explained according to Hagerman et al(1990) and Baden et al(1994);where the lowest values obtained in the winter correspond to the period of the year with the highest percentage of empty stomachs. This was supported by Schirf et al (1987) who reported that food deprivation in P. clarkii resulted in a significant decrease in muscle carbohydrate. Similar results were obtained by Rosa and Nunes ( 2003a) on deep-sea decapod crustaceans since the glycogen content in abdominal muscles of these animals reached the lowest values in winter.…”

ABSTRACThe current study was conducted to investigate the effect of environmental factors and sex difference on the physiological status of the exotic red swamp crayfish (Procambarus clarkii) in Egypt along four successive seasons during the period from 2005 to 2006. Animals were collected from El-Mansourya canal at Giza governorate . Water and sediments were collected from three different aquatic habitats in order to determine the least polluted water quality region for collecting specimens used in the current study . These sites were: El-Mansourya canal (site I), El-Mouhit drain (site II) and Bany Magdoul canal (site III). During the four seasons, measurements of physicochemical characteristics of water and sediments revealed elevated annual concentrations for ammonia, nitrates, nitrites, in addition to high chlorosity in site II and heavy contamination with iron, copper, manganese, zinc and aluminum in site III; whereas site I was the least polluted and possesses the most transparent water with lowest electrical conductivity than the other sites. Lowest water temperature was recorded during winter and the highest one was during summer; while at the same season no wide difference has been found among the three habitats. Biochemical analysis of the main edible parts of crayfish inhabiting El-Mansourya canal (site I) revealed that males showed little rise in their muscle water content but females exhibited significant higher lipid content almost the year round. No marked changes were observed in the protein content in both sexes. Females also showed more glycogen accumulation in their abdominal muscles but lack statistical significance except during spring . In both sexes, highest levels for water content were reported during winter and for lipid during spring while for glycogen were during autumn . The lowest content for lipid was during autumn and for glycogen during winter for both sexes. The results indicate that seasonal changes in biochemical composition of edible parts of both sexes could reflect different physiological processes related to sex difference as an expression of animal adaptive response, an ecophysiological adaptation, to habitat quality and environmental conditions along the four successive seasons in Egypt.

“…Thus, during trawling extreme exercise is induced in the capture phase (Newland et al 1992;Albalat et al 2009) and handling on deck after trawling or after trapping in creels involves periods of emersion in the air (Schmitt & Uglow 1997;Harris & Andrews 2005a,b;Ridgway et al 2006b). Holding in pounds or cages may lead to prolonged starvation (Schirf et al 1987), and seasonal effects causing changes in climatic factors such as water or air temperature (Giomi et al 2008) and biological factors such as the moulting state, or infection (Stentiford et al 2001a;Chang 2001) may also apply. Gaining an understanding of the relative severity of these stressors is important for recommending the most effective way to reduce physiological threats to the survival of these animals during holding and live transportation, and also helping to extend the shelf-life (use by date) of whole animals or tails, and improve their overall quality.…”

The effects of four different ante-mortem stressors (exercise, emersion, starvation and a patent infection with the parasite Hematodinium sp.) on post-mortem processes have been investigated in the abdominal muscle of Norway lobster Nephrops norvegicus by measuring changes in the pH, the levels of glycogen, L-lactate, arginine phosphate, ATP, ADP, AMP, IMP, HxR, Hx and the adenylate energy charge (AEC) over a time course of 24 h with samples being taken at 0, 3, 6, 12 and 24 h. The acute stresses of intense exercise and 2 h emersion resulted in a premature onset of anaerobic glycolysis, leading both to an enhanced glycogen depletion rate and an early accumulation of L-lactate. The chronic stressors, starvation and parasite infection, resulted in a complete ante-mortem depletion of muscle glycogen and consequently the failure of post-mortem glycolytic fermentation. Post-mortem pH and ATP inter-conversion were significantly altered in chronically stressed animals. Ante-mortem, a rapid, almost complete depletion of arginine phosphate was observed in all stress groups. The AEC was altered significantly by all stresses, indicating a strong energy demand. The findings suggest that ante-mortem stressors strongly influence the post-mortem biochemical processes. The laboratory-based results are compared to 'field' data and effects on post-harvest product quality are discussed.

“…Nutritional deprivation is a natural part of the life cycle of many aquatic organisms and results from winter torpor, seasonal variation of food availability, behavioral modifications during mating/spawning (Schirf et al 1987) and also parasitism (Walkey & Meakins 1970, Astete-Espinosa & Caceres 2000. Most species reduce their metabolic rate and deplete protein, carbohydrate, glycogen and/or lipid reserves during nutritional stress (Hazlett et al 1975, Regnault 1981.…”
