“…Data on whole body composition of the shrimp suggest that there was an inverse relationship between the moisture content and weight gain, whereas the percentages of protein, fat, and ash were directly related to weight gains. Similar results have been found in other studies (Stuck et al, 1996a;Lim, 1997).…”

“…This result implies that shrimp in fish flesh and shrimp flesh treatments suffered from nutritional stress. Similar sublethal stress such as starvation, nutritional restriction, infection, and environmental pollution would cause increase in body moisture content in crustaceans (Wang & Stickle, 1988;Stuck et al, 1996aStuck et al, , 1996bLim, 1997;Wu & Dong, 2002a, 2002b.

Five diets, i.e., fish flesh (FF), shrimp flesh (SF), clam foot (CF), polychaete worm (PW), a formulated diet (FD), and a mixture of the preceding five diets (MD), were fed to Chinese shrimp, Fenneropenaeus chinensis (initial weight 1.53 ± 0.05 g) for 30 days to investigate the effects of different diets on the energy allocation and body composition of Chinese shrimp. It was found that the model of allocation of ingested energy changed according to diet, and significant differences existed among treatments. Moisture, protein, lipid, ash content, and gross energy content of shrimp fed different diets also showed significant differences. The relationships between food conversion efficiency (FCE) and gross energy to protein content ratio (GE : P), between net conversion efficiency (NCE) and GE : P, between FCE and lipid content (L), and between NCE and L were well expressed with their respective models. The optimal crude lipid (L) content and GE : P were calculated from these models on the assumption that when optimal FCE and NCE were reached, then the L and GE : P were optimum. The optimal crude lipid contents were 23.1%, 29.08%, 19.82%, and 24.93% while the FCE and NCE were described in terms of protein and energy. When FCE and NCE were described in terms of dry matter, protein, and energy, the optimal GE : P were 36.11 KJ/g, 38.75 KJ/g, 37.22 KJ/g, 37.43 KJ/g, 38.49 KJ/g, and 37.32 KJ/g, respectively. The results indicate that natural diets are feasible to be used for studying the nutritional requirements and to analyse the primary ingredients that affect the utilization of these by the shrimp. RÉSUMÉCinq types de nourriture, soit la chair de poisson (FF), la chair de crevette (SF), le pied de coquillage (CF), les vers polychètes (PW), une formule composée (FD), et un mélange des cinq précédents types (MD), ont été proposés à la crevette chinoise Fenneropenaeus chinensis (poids initial 1,53 ± 0,05 g) pendant 30 jours, afin d'étudier les effets des différentes nourritures sur le gain d'énergie et la composition du corps de la crevette chinoise. On a mis en évidence que le modèle de répartition de l'énergie ingérée variait suivant l'aliment, et des différences significatives existaient en fonction des traitements.

“…In the current experiment, F. chinensis showed no different response to DO changes in wet weight gain when DO was above 3.10 mg/L, but refer to no difference in dry weight gain, DO should be above 4.13 mg/L, which was close to the corresponding levels (at or above 4 mg/L) for P. aztecus and P. setiferus (Renaud 1986). The difference between the effects of low DO on wet weight and dry weight gain indicated that deficient oxygen supply might cause the rising of body moisture content like other stresses (Wang and Stickle 1988; Stuck et al 1996a, 1996b; Lim 1997). So the growth of juvenile F. chinensis would not be affected by DO above 4.13 mg/L.…”

Information about the effect of hypoxia exposure on energy allocation is helpful for better understanding how aquatic animals tolerate and adapt to a hypoxic environment. The growth, molting, and energy allocation were investigated in juvenile Fenneropenaeus chinensis exposed to five different dissolved oxygen (DO) seawaters (2.09 ± 0.15, 3.10 ± 0.29, 4.13 ± 0.25, 4.73 ± 0.12, and 5.48 ± 0.09 mg/L DO) for 30 d. When DO was below 4.13 mg/L, the growth of shrimp was depressed. Feed ingestion and feed conversion efficiency decreased with the decrease of DO. Less feed ingestion was caused by lower daily metabolic energy. Higher proportion of ingested energy lost in metabolism, exuviations, and nitrogen excretion caused lower feed conversion efficiency. More energy lost in exuviations, lower survival rate, soft carapaces of dead shrimp, and cannibalism were found in oxygen deficient groups and it implicated that hypoxia could delay the shrimp recovering from molting and cause cannibalism and higher mortality. The results indicated that hypoxia was an important factor affecting the amount and fitness of shrimp stock because it could cause a high rate of mortality and growth depression.

“…The ability to withstand and recover from periods of nutritional stress is an important adaptation for survival of any organism that must sporadically endure periods of limited food supply (Stuck et al 1996). For L. santolla although there were no significant differences detected in the relative quantity of food consumed between seasons among mature crabs, during spring months the percentage of empty stomachs was higher and differences in the occurrence of different types of food was detected (Comoglio & Amin 1996).…”

Resumen.-Este estudio evalúa los efectos del ayuno en la centolla Lithodes santolla. Machos adultos de la centolla fueron mantenidos en condiciones de ayuno durante 12 días. Cada 3 días (i.e., 0, 3, 6, 9 y 12 días) se evaluó en subgrupos el consumo de oxígeno, la excreción de amonio, la relación atómica O:N y la composición bioquímica del hepatopáncreas. El índice hepatosomático (calculado individualmente como el porcentaje del peso húmedo del hepatopáncreas en relación al peso húmedo total del individuo) fue menor a 12 días de ayuno, coincidiendo con el menor contenido de proteínas en el hepatopáncreas. No se detectaron diferencias significativas en la composición bioquímica porcentual (contenido de agua, materia orgánica y cenizas). El contenido lipídico no fue significativamente diferente durante el experimento aunque el mayor valor fue registrado a los 3 días de ayuno. Entre los 3 y 9 días de ayuno, la excreción de amonio y el contenido de proteínas en el hepatopáncreas fue mayor y la actividad enzimática de tripsina, menor. Esto podría indicar que el catabolismo de proteínas fue el más importante durante ese período. Este hecho también se confirma por los bajos valores de O:N detectados en el período mencionado. A los 9 días de ayuno se incrementó el consumo de oxígeno, acompañado con un alto valor de excreción de amonio, originados probablemente por una demanda extra de energía producida por el ayuno. Se concluye que L. santolla para estos rangos de tiempo experimental utiliza proteínas como fuente primaria de energía.Palabras clave: Cangrejos, consumo de oxígeno, excreción de amonio, lípidosAbstract.-This study evaluates the effects of starvation on the physiological aspects of the southern king crab, Lithodes santolla. Adult males of this crab species were maintained in starving conditions for 12 days. Every 3 days (i.e., 0, 3, 6, 9 and 12), subgroups were taken to evaluate oxygen consumption, ammonia excretion, O:N atomic ratio and biochemical composition of the hepatopancreas. The hepatosomatic index (calculated individually as the percentage of hepatopancreas wet mass in relation to the total body wet weight) was lower at 12 days starving period, coincidentally with the minor amount of hepatopancreatic protein. No significant differences in the relative biochemical composition (percentage of water, organic matter and ash) were detected. The lipid content was not significantly different during the experiment; nevertheless the higher value was detected at 3 days of starvation. Between the 3 and 9 days of fasting period ammonia excretion and hepatopancreatic protein were higher and the trypsin activity, lower. These results could indicate that protein catabolism was the most important in these periods. Besides, the lower values of O:N detected for all periods confirm this effect. On the ninth day of starvation oxygen consumption increased together with a high value of ammonia excretion probably due to an extra energy demand produced by starvation. We conclude that L. santolla in the experimental time-ran...
