“…The dietary protein in the present study was supplied mainly by high quality fish meal while the diets in the previous study were formulated mainly by conventional low‐cost ingredients with low protein quality (Hossain & Jauncey 1989). The growth in terms of SGR, feed conversion and per unit production performance of T. putitora was satisfactory and comparable to that reported for other carps (Nandeesha, Gangadhara, Manissery & Venkataraman 2001; Virk & Saxena 2003), and, in carp polyculture, mahseer would perform even better than other carp species. Keshavanath, Gangadhar, Ramesh, Van Dam, Beveridge and Verdegem (2002) reported that T. khudree exhibited better growth gain and per unit production than another carp fish, Labeo fimbriatus , in the same experimental conditions.…”

A feeding trial was conducted to study the e¡ect of six iso-energetic diets containing 25, 30, 35, 40, 45 and 50% crude protein (CP) on growth, survival and feed conversion ratio (FCR) as well as the protein requirement of an endangered cyprinid,Tor putitora. Triplicate groups of ¢ngerlings with initial total length of 10.0^11.0 cm and weight of 12.0^12.5 g were reared in earthen ponds and fed diets at 5% of body weight for 120 days. Performance was evaluated on the basis of total length gain, body weight gain, survival rate, feed e⁄ciency, FCR, protein e⁄ciency ratio, speci¢c growth rate, energy retention, gross and net yield in kg ha À1 . Whole-body carcass composition of ¢sh was analysed at the start and the end of the experiment. Growth and FCR were in£uenced signi¢cantly (Po0.05) by dietary CP contents; higher growth and lower FCRs were obtained with increasing dietary protein. Dietary protein also in£uenced the whole-body carcass composition of the ¢sh. Higher protein and ash, and lower moisture and lipid in the whole body were observed with increasing dietary protein. Broken-line regression analysis indicated that the optimum dietary protein level for maximal growth of mahseer lies between 45% and 50% (45.3%). Overall feed utilization and growth performance of the ¢sh is comparable to that of other aquaculture species and the ¢sh o¡ers high potential for commercial aquaculture.

“…Results of the bromatological analysis for amaranth and quinoa seed meals were similar to the results reported by Virk and Saxena () and Koziol () respectively. Amaranth and quinoa have a protein content (Table ) that is comparable to alfalfa (173 g kg −1 ) but higher than the values reported for oats (118 g kg −1 ), sorghum (111 g kg −1 ) and wheat (122 g kg −1 ) (NRC ).…”

“…There are a few reports on the use of amaranthus in aquafeeds. Virk and Saxena () studied amaranthus seeds as replacement for rice bran and groundnut oil cake at three different levels (20%, 35%, and 50%) in diets for common carp, Cyprinus carpio , and rohu, Labeo rohita , under a semi‐intensive production system. Growth in terms of body weight gain was maximum in fish fed on diets containing 200 g kg −1 amaranthus seeds.…”

Evaluation of amaranth (Amaranthus caudatusL.) and quinoa (Chenopodium quinoa) protein sources as partial substitutes for fish meal inLitopenaeus vannameigrow-out diets

Two groups of isonitrogenous diets formulated by replacing 15%, 25%, 35% and 45% of fish meal protein by amaranth meal and quinoa meal were used to evaluate the performance of Litopenaeus vannamei. Growth showed significant reduction (P < 0.05) in the group of shrimp fed with amaranth diets, with diet A15 showing the best specific growth rate (SGR = 2.81% day À1 ), but after the control diet AQ0 (3.07% day À1 ). Diet A15 had significantly (P < 0.05) the best digestibility of dry matter (79.7%) and protein (88.4%) without differences compared to control diet AQ0 (75.1% and 85.2%). Replacement with quinoa meal at any level tested did not significantly affect (P > 0.05) the shrimp growth performance. Shrimp fed with quinoa diets showed better SGR (3.05% day À1 ) than those shrimp fed with amaranth (2.56% day À1 ). No differences in feed conversion ratio appeared in either of the protein sources, but quinoa diets presented a better average (3.13) than amaranth diets (4.01). The apparent digestibility of dry matter and protein for quinoa diets was similar for all diets, but they were statistically different (P < 0.05) from the control diet. We conclude that quinoa meal can replace fishmeal up to 45%, whereas it can be replaced with amaranth meal up to 15%, without adverse effects on growth and survival.

Effects of supplemental feeding with cereals (rye, triticale, maize and the unsupplemental control group) on fat content in flesh of 3‐year‐old common carp (Cyprinus carpio) were the subject of study carried out at four ponds (Czech Republic, Central Europe) during the growing season. The main result was that supplemental feeding with cereals to the same energetic level was associated with varying growth and fat content in the flesh of common carp. At the end of the experiment, the stock of fish supplementally fed with maize was found to have the highest fat content (112.7 ± 15.6 g kg−1), while the lowest value of fat content was found in the control group (56.8 ± 9.4 g kg−1). The carps supplementally fed with rye were found to have a higher fat content (90.1 ± 19.0) than those supplementally fed with triticale (84.3 ± 15.7 g kg−1). Established average fat content values (except for maize) were at the level that indicate a high sensory quality of carp flesh during the whole growing season.
