“…In fact, increases of faeces were recorded in animals fed boiled or ovendried shrimp, showing that this type of meat was not adequately digested. Previous work on S. officinalis showed that diets made with fish meal and supplemented with sardine and squid paste produced similar results (high production of faeces and low absorption efficiency), showing that when protein sources were modified (as the fish meal) assimilation efficiency was limited (Domingues 2007a). The reason for that limited digestibility of processed protein could be related to changes in protein structure.…”

“…The reason for that limited digestibility of processed protein could be related to changes in protein structure. Although there are some unsolved questions regarding protein structure and digestibility capabilities of cephalopods, evidence suggests that processed protein such as fish surimi paste (Castro et al 1993), catfish processed paste (Domingues et al 2005) or fish meal enriched with squid paste (Domingues et al 2007a;Rosas et al 2007) limit the digested energy in cephalopods.…”

“…These experiments demonstrated that large juveniles and adults readily accepted prepared diets. 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).…”

“…The two main factors that have prevented large-scale culture are the dependence on live prey during the first part of the life cycle (O'Dor and Wells 1987;Lee et al 1991;Lee 1994;Domingues 1999) and the lack of a successful artificial diet for cephalopod culture (Domingues et al 2007a). Considerable cost reductions of up to 80% can be estimated, particularly when using commercial production methods, if prepared diets could successfully replace natural prey (Domingues et al 2005.…”

“…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). Consequently, the formulation of such a diet is still in the early stages, being one priority for the successful large-scale culture of cephalopods (Lee 1994;Domingues et al 2006Domingues et al , 2007a.…”

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.

We quantified the uncertainty due to biota-related parameters in estimated bioaccumulation factors (BAFs) of persistent organic pollutants for fish through Monte Carlo simulations. For this purpose, the bioaccumulation model OMEGA (Optimal Modeling for EcotoxicoloGical Applications) was parameterized based on data from the existing literature, analysis of allometric data, and maximum likelihood estimation. Lipid contents, fractions of food assimilated, the allometric rate exponent, normalized food intakes, respiration and growth dilution rates, and partial mass transfer resistances in water and lipid layers were included as uncertain parameters. The uncertainty in partial resistances was particularly important in the estimation of the rate constants for chemical intake from water by fish. Uncertainties in the fractions of food assimilated and partial water layer resistances from and to food were particularly important in the estimation of the rate constants of chemical intake from food. The uncertainty in the model outcomes for the bioaccumulation factors for fish was a factor of 10 (ratio of 95th and fifth percentile estimates), which was mainly caused by the uncertainty in the lipid fraction. For chemicals with a K(OW) of 10(3) to 10(6), the uncertainty in the lipid contents of fish accounted for more than 50% of the uncertainty in the estimated bioaccumulation factor. For chemicals with a high K(OW) (10(7) and higher), the fractions of food assimilated and partial resistances also contributed to uncertainty in the estimated bioaccumulation factor (up to 60%). A case study showed that uncertainty in estimated BAF for nonpersistent substances can be dominated by uncertainty in the rate constants for metabolic transformation.
