“…Experimental diets were well accepted and consumed by crayfishes which reflected a good growth in all treatments overcoming growth results previously reported in the same species by Carmona Osalde et al and Rodriguez-Serna et al [17,15]. Feeding diets containing PO in 50 and 100% of added oil had similar growth which leads the possibility of eliminating FO from crayfish food.…”

“…Experimental organisms doubled their size every fifteen days reaching in three months a maximum average weight of 3.67 g and 53.98 mm in size. Percentage of weight gain fluctuated between 537 and 807%, that represent eight fold increased than those results reported by Carmona Osalde et al [15] with different protein/lipid ratios and [18] using shrimp commercial food. No significant differences were found in survival, but best results were observed with D1.…”

“…Over this period of time no growth or mortality was taken into account because of the high density managed. In non spawned females ovarian development was determined at the end of the experiment by dissecting them and observing differences in oocyte color [15]. The gonadosomatic index (GI) was calculated according to Pawson et al [16] …”

A 12-week feeding study was carried out to establish the effect of partial or total substitution of fish oil by plant oil in experimental fed diets in crayfish juveniles (Procambarus llamasi). Three isonitrogenous (30% crude protein) and isoenergetic (15.1 kJ/g) practical diets were formulated with 100% fish oil (FO), 100% plant oil (PO), and 50% FO-50% PO. The crayfish were raised on plastic tanks without water exchange, constant aeration, PVC shelters, with an average water temperature of 26 ± 1°C. Uneaten food and fecal residues were siphoned out from the tank bottom each morning. Crayfish total body weight (BW) and total length (TL) was measured every two weeks. Results showed that the use of plant oil did not significantly modified (p>0.05) growth performance, survival or maturity of experimental organisms. All diets were offered to apparent satiation twice a day. Fed was consumed showing good results in all performance growth parameters and maturity index. In conclusion the present study clearly supported the possibility of total or partial substitution of fish oil by plant oil for crayfish. Despite the absence of fish oil as attractant in the diet with 100% PO, its acceptance was as good as the one containing it. P. llamasi demonstrated the feasibility of using a vegetable oil as lipidic energy source, which allows lowering costs in the use of fish oil about 66%.

“…Lipid content in the feed was, in accordance to the majority other crayfish studies, low (Xu et al 2013;Carmona-Osalde et al 2005;Ghiasvand et al 2012) and should be enhanced with the crayfish age (Ackefors et al 1992). Although higher lipid levels were stated , the feed and its lipid content was chosen in accordance to the natural nutrient for A. astacus supply stated by Hager (2003).…”

Growth performance of Noble Crayfish Astacus astacus in recirculating aquaculture systems

There is growing interest in using recirculating aquaculture systems (RAS) to raise noble crayfish Astacus astacus a valuable and once plentiful food species in Europe, now a highly endangered species. The growth and survival of A. astacus was compared in growth trials in RAS and open-pond systems (OPS) over a period of 2 months. Energy and lipid content of available diets and crayfish tissue were also determined. Growth of A. astacus during summer was significantly (p \ 0.01, one sample t test) higher in OPS (SGR 1.23) than in RAS even at the highest feeding ration provided at 5 % bw/d -1 (RAS HI SGR 0.78 ± 0.06). OPS crayfish also had significantly (p \ 0.01 OPS vs. all RAS treatments; Pairwise Wilcoxon) higher lipid content (8.51 %) than RAS crayfish (RAS HI 5.73 %, RAS MED 6.93 %, RAS LOW 5.92 %). Survival rates in RAS were, however, 100 % compared with previous observations in OPS of approx. 70 %. While results showed OPS growth exceeds than that in RAS in the short term, RAS survival rates and annualized growth performance may outweigh this disadvantage, particularly if optimal artificial diets for RAS holding are provided. Feed and crayfish analysis indicated that culturing A. astacus in RAS require a diet protein content exceeding 30 % and lipid content of \13 %, indicating that the carp diet supplied was not optimal. RAS culture allows this valuable species to be cultured in controlled, disease-free enclosed systems-resulting in high-value food products as well as high-quality seedlings for restocking purpose.
