“…Our results suggest that AG appears in the DG when more complex nutrients are digested 180 min after feeding; for instance when AG was extracted from crab tissues. In crustaceans, Chol is an essential nutrient stored in the DG, muscle and hemolymph where it is mobilized and used as a precursor for molting and growth hormones (Teshima 1997, Pascual et al 2003, Rosas et al 2004, 2007a. The characteristics of Chol explain why this molecule showed 2 peaks in the O. maya DG, as it was ob tained from the food on 2 occasions: from soluble nutrients in the first chyme pulse (probably soluble cholesterol found in the hemolymph and other tissues) and later, when more complex nutrients were digested.…”

O. maya and O. mimus adapt well to captivity, eat freeze-dried diets, and can reach high market value (Zuñiga et al 1995, Salas et al 2006, thus making both species good candidates for marine aquaculture (Iglesias et al 2014).…”

“…Feeding rates for S. officinalis on prepared diets were always considerably lower than a normal laboratory maintenance diet of crustaceans (Pascual 1978;Richard 1971Richard , 1975Boletzky 1979;Castro et al 1993;Castro and Lee 1994;Lee et al 1991;Forsythe et al 1994;Domingues et al 2001bDomingues et al , 2002Domingues et al , 2003aDomingues et al , b, 2004Domingues et al , 2006Domingues et al , 2007aBoucaud-Camou 1999, 2001;Koueta et al 2000). Nevertheless, high feeding rates on prepared diets were reported for the Yucatan octopus, Octopus maya (Domingues et al 2007b;Rosas et al 2007). Growth and survival of cephalopods with these diets are comparable to fish larvae being transitioned from natural to prepared diets (Dabrowski et al 1978;Lindberg and Doroshov 1986).…”

The diet of frozen grass shrimp (P. varians) was compared to similar grass shrimp that had suffered either boiling, drying at 60°C, or freeze-drying by lyophilization at -40°C. In experiment 1, cuttlefish fed the frozen shrimp were significantly larger (P \ 0.05) at the end of 10 days and at the end of the experiment, compared with those fed the boiled or dried shrimp. Growth rates were also higher for cuttlefish fed the frozen shrimp, compared with the remaining two. Growth rates were also higher for cuttlefish fed the frozen shrimp, compared with the remaining two. In experiment 2, there were no differences in weight (P [ 0.05) between cuttlefish fed the frozen or the freeze-dried shrimp, whereas cuttlefish fed the dried shrimp were smaller at the end of the experiment. Growth rates of cuttlefish fed the dried shrimp were lower, compared with those for cuttlefish fed the frozen and freeze-dried shrimp, with no significant differences (P [ 0.05) between them. Cuttlefish fed freeze-dried and frozen shrimp showed a higher trypsin activity compared to animals fed boiled and dry (60°C) shrimp. A higher proportion of absorbed energy was channelled into biomass production in animals fed frozen and freezedried shrimp (56% and 43%, respectively) than for animals fed oven-dried (60°C) or boiled shrimp. The heat treatment suffered by the shrimp, either dry or wet, negatively affected diet quality, probably due to denaturation, and loss (by boiling) of proteins and amino acids. Additionally, the heating processes may have oxidized the lipids to a large extent, contributing to the loss of the polar lipids (polyunsaturated fatty acids), which are essential for cephalopods as for other organisms. Freeze-drying by lyophilization (negative temperatures) did not affect the nutritional quality of the shrimp.

“…R. harrisii belongs to ammonotelic organisms which excrete mainly soluble ammonia as a deamination product and only small proportion of other nitrogenous wastes like urea or free amino acids (Regnault 1987, Chen & Kou 1996, Weihrauch et al 2009). According to Lucas (1993), Radford et al (2004) and Rosas et al (2007), an increase in the metabolic rate is observed when ingested materials are biochemically processed and then transformed into new molecules, used in further physiological and biochemical traits. Digestion of highly energetic food items, consisting mainly of proteins and lipids, is a complex process.…”

Rates of physiological processes and bioenergetics of the Harris mud crab Rhithropanopeus harrisii were determined during a 7-day experiment on adult males (mean wet weight 0.83 ± 0.16 g) exposed to temperatures of 15ºC and 20ºC (S = 7). The results show that the change in temperature by 5ºC caused detectable changes in locomotor activity, food consumption and faeces production and significant (p < 0.05) changes in metabolic rates. Food assimilation efficiency and the ammonia excretion rate did not change significantly (p > 0.05). The energy expended on metabolic processes was similar at both temperatures (15ºC and 20ºC) and amounted to 17.7 ± 6.4% and 16.7 ± 4.3% of the assimilated energy, respectively. Similar values were obtained for net production efficiency K2 (P/A) at 15ºC and 20ºC, i.e. 80.4 ± 22.4% and 82.9 ± 9.7%, respectively. The amount of energy available for production was 2-fold higher at a temperature of 20ºC than at 15ºC and amounted to 103.69 ± 25.61 and 206.40 ± 20.76 J d -1 g -1 wet wt, respectively. The results show that from the bioenergetic point of view, higher experimental temperature is more "profitable" for adult R. harrisii specimens because it provides better conditions for the growth and reproduction.
