Farmers often feed their fish with vegetable matter in the morning and with pellets in the afternoon (Wang and Zhang, 2005) and this leads to higher profit margins (Lu and Deng, 2003). The feed coefficient is 4.9, if a part of the green fodder is added, the feed coefficient is 13. Grass carp feed formulation has received considerable attention, in particular the replacement of expensive ingredients with cheaper alternatives. The feed coefficient is 15. Fragment peptides from shrimp waste have also been reported to increase growth, feed utilization and protein retention in grass carp (Feng and Liu, 2005). In order to balance the growth of fish and the feed coefficient, the most appropriate amount for each feeding and daily feeding should be about 90% of the total body weight of the fish. Probiotics may also be used to increase growth and to increase resistance to low dissolved oxygen levels (Xiang et al., 1995). Straw powder 80%, bean cake 10%. Chinese medicines are often added as a prophylaxis. Feed conversion ratios on formulated pellets is around 1.5-1.8:1 and with high quality feeds can be as low as 1.1:1 (Tian et al., 2005).

Table 10 shows the digestibility of various feed ingredients (Luo et al., 2001; Lin et al., 2001) and Table 11 lists the apparent amino acids digestibility coefficients for 25 feed ingredients (Ye et al., 2003). Triploid grass carp will also control filamentous algae, when the fish are small. For example, some farmers feed grass carp fry of 30mm TL (stocked at 6 000 fry/1 000 m 2) on bean curd by-products for one week and then switch to duckweed at 60-128 kg duckweed/1 000 m 2. Stay tuned to this channel for updates on the carp. Newly hatched grass carp feed on benthic invertebrates and zooplankton until they reach about two inches, when they switch to vegetation. Grass carp is cultured in many countries and hence diet formulation varies with the availability of local ingredients. J. Int. Grass carp larvae start feeding on protoza, rotifers and some small Cladocera. Due to various factors that impact triploid grass carp feeding, it is impossible to precisely predict the exact number of fish to stock to achieve the 20-30% . To increase productivity, growth and profitability, formulated feeds are becoming more popular in intensive grass carp culture (Table 8 and Table 9) (Shao et al., 2004; Duan and Duan, 2005).

C. Formulation of compound additive for herbivorous fishes Grass Carp: Grass carp is a typical herbivorous fish, adults mainly eat weeds, fish fry in the early stage of cultivation mainly feed tiny protozoan, but they like to eat artificial fine feed in each growth stage. The foregoing experience with my sterile grass carp stands in contrast to developments in northwest Ohio’s Sandusky and Maumee rivers, and the great body of water that they feed, Lake Erie. Almost all ingredients generally used in aquaculture feeds can be used for grass carp. Grass carp suppliers will often quit sell grass crap in summer months due to the problems with hauling the fish in high temperatures. If the feeding amount is more than 100% of the satiety, in addition to waste, it will pollute the water quality and increase the cost of water quality management. The feed coefficient is... 2.Formula for Grass Carp Feed Vitamin C at 150–300 mg polyphosphate ascorbic acid/kg diet improves growth and feed utilization (Wen and Liao, 1996; Shi et al., 2001; Lin et al., 2003). 1.Feed must be granulated, sinking pellets or floating pellets.

Supplementary dietary taurine, at 600mg/kg diet, increases fish growth and protein efficiency ratio, while the inclusion of beta-glucanases (500 IU/kg diet) increases digestibility, somatic growth and decreases FCR (Gao et al., 2006b). Vitamin and mineral premix and feeding attractants comprise around 2-5 percent of the feed. For example, addition of 0.5 percent Pulsatilla chinensis to the diet has been found to increase the immune response of grass carp (Tao et al., 2007). In Michigan, one of our most troublesome aquatic weeds is the non-native Eurasian watermilfoil. An 8-week feeding trial was conducted to evaluate the effects of xylooligosaccharde (XOS) on growth, immunity and disease resistance of juvenile grass carp (Ctenopharyngodon idella).Fish (3.05 ± 0.01 g) were fed with diets containing XOS at levels of 0, 0.05 %, 0.1 %, 0.2 %, 0.4 % and 0.6 %. The feed coefficient is 1.9. Supplementary dietary taurine increases the flesh protein content by about 2-3 percent and decreases water content by about 3 percent (Luo et al., 2006). Invader from the East The first grass carp arrived in the U.S. from Taiwan and Malaysia in 1963, sent to aquaculture facilities in Alabama and Arkansas, where the plan was to use the species to control unwanted aquatic vegetation. So as to achieve the best production effect and benefit. 2.Formula for Grass Carp Feed Diet formulation affects meat quality. It is used as edible fish. After 20 days the fish grow to around 70 mm (total length) and the quantity of duckweed is adjusted according to fish biomass. Grass carp (Ctenopharyngodon idella) was cultured in the inundated low-lying coastal wetlands using Asian watergrass (Hygroryza aristata) as feed for 6 months.The study was carried out with three treatments, each with three replications. Grass carp do not eat all plants with equal enthusiasm, though. Grass carp consume from 20 to 100% of their body weight in vegetation per day depending on their size and water temperature, although they stop feeding at temperatures below 50°F. Feed requirement determination of grass carp (Ctenopharyngodon idella) using a hybrid method of bioenergetics factorial model and fuzzy logic control technology under outdoor pond culturing systems. improved feed formulation and on-farm feeds and new methodological approaches towards fish and crustacean nutrition research within semi- ... nobilis (a zooplankton filter feeder), grass carp Ctenopharyngodon idella (a herbivo-rous macrophyte feeder), and common carp Cyprinus carpio (an omnivorous bottom feeder). Dabrowski and Kozak (1979) reported that growth, protein efficiency ratio and apparent net protein utilization of grass carp fry (0.4 g) is optimized when fed a diet containing 40 percent fishmeal. Grass carp is an herbivorous fresh water fish. After 15-20 days, when the early juveniles are approximately 26 mm TL, they start to ingest duckweed and soon there after feed almost exclusively on macrophytes (Ni and Wang, 1999).

A video of the first step we have taken to address our lake's weed problem. Leaf meal and grass meal are also used. Extrusion increases the digestibility of some feed ingredients, especially those ingredients with high carbohydrate levels (Guo et al., 2005). Grass carp can grow up to 100 pounds. Price of feed with high protein content is higher, but it is worth spending, especially when the average weight of fish is not less than 50 grams. plant coverage target. If the feeding amount reaches 100% of the satiety, the growth will be good, but the feed coefficient will be relatively large. Feed should be used up within 6 weeks after production, if the storage time is too long, its vitamins and other nutrients will lose, or be damaged mildew and other microorganisms. The amount of fish feed is mainly related to the water temperature and the average body weight of fish. Egg diameter is approximately 1.5 mm (Ni and Wang, 1999). Aca.

Corn flour 70%, fish meal 10%, bean cake powder 15%, wheat bran 15%, other material (based the total material metering) can be: sweet potato powder 12%, salt 0.5%, growth substance 2%, calcium hydrogen phosphate 2%. Grass carp (Ctenopharyngodon idella), also known as white amur, is a freshwater fish that is reportedly the second-most farmed fish (after silver carp) in the aquaculture industry, with five million tonnes-per-year produced on average globally. In this study, we investigated the influences of dietary iron deficiency on intestinal immune function as well as underlying signaling of on-growing grass carp (Ctenopharyngodon idella).Fish were fed with six graded level of dietary iron for sixty days, and a fourteen days’ challenge test under infection of Aeromonas hydrophila thereafter. II.How to Choose Feed for Freshwater Fish The goal of feeding in pond is to feed the fishes with required quality, quantity, and feeding time per day. Feed ingredients were collected from the local market and were analyzed for protein, fat, ash, fiber, moisture content Rice bran 40%, wheat bran 38%, bean cake 10%, fish meal 10%, yeast powder 2%. If the amount of feeding is only 80% of the satiety, the feed coefficient will be relatively low, but the growth will be slow. 3.The protein content of feed is generally 32 – 36%. Some terrestrial grasses and agricultural by-products such as rice bran, oilseed cakes can also be used as food. Dietary photosynthetic bacteria have also been shown to increase grass carp growth rate under pond culture conditions (Zhang et al., 1996; Lin, 2001; Chen and Zhang, 2005; Zhang et al., 2007).
