Benefits of technology
This patented technology improves the performance and usability of green clay (Blue Crab) feeds while reducing their costs compared to traditional methods such as poultry or fish farming. By mixing specific types of materials together, these new ingredients enhance the properties of both raw material and finished products like breadings made from them. These mixed compositions also have an enhanced ability to resist decomposition during storage without losing its original tastefulness when fed into humans through consumption. Overall, they provide technical benefits including increased yield, reduced waste, lower energy usage rates, better overall value creations, reduction of harm caused by nitrogen fertilizers, prevention against algae growth, and improvement in animal welfare and environment safety.
Problems solved by technology
This patented technical problem addressed in this patent relates to improving the efficiency at producing green crops from seafood (Blue Crab) populations due to its vulnerability towards environmental factors like saltwater or harmful chemical substances during harvesting processes. Current methods involve either create an excessive amount of waste material containing valuable components or use costly special facilities to treat these materials before they reach consumers. Therefore there is a desire to develop new ways to enhance the growth potential of blue crocs while reducing pollution caused by traditional fertilizers used alone.

Embodiment 1
[0020] Taking the production of 100kg of mud crab hard pellet feed with a diameter of 3mm and a length of 1cm as an example, 44kg of fish meal, 6kg of squid meal, 10kg of peeled soybean meal, 21.95kg of high-gluten flour, 2kg of multivitamin, 10kg of shrimp shell powder, and 3kg of dihydrogen phosphate Calcium is pulverized and passed through an 80-mesh sieve for mixing. Take 0.6 kg of xanthan gum, 0.3 kg of sodium carboxymethyl cellulose, and 0.15 kg of sodium alginate and mix to obtain a composite binder, and then mix with the above-mentioned raw materials. Put it in a feed mixer, add 2kg of fish oil to expand and stir evenly step by step, use a 3mm granulating abrasive, extrude into strips and make 1cm long hard pellet feed by hand or machine. Put the prepared feed into a steamer, steam it in water for 15 minutes, dry it at 50°C for 24 hours, and store it in a refrigerator at 0°C.

Abstract
The invention discloses a green crab fodder and a simple preparation method thereof. The green crab fodder is prepared from 35%-45% of fish meal, 8-15% of shrimp shell powder, 4-6% of sepia powder, 8-12% of peeled bean pulp, 18-25% of high gluten flour, 1-3% of monocalcium phosphate, 2-3% of fish oil, 2% of multidimensional ore and 1-2% of compound adhesive, wherein the compound adhesive is prepared from xanthan gum, sodium carboxymethylcellulose and sodium alginate in proportion. An extruding particle pelletizing method and a simple steam curing method are adopted for curing and bonding the compound adhesive and starch components in the fodder provided by the invention under high temperature, so that the degree of gelatinization is greatly promoted; the prepared fodder has complete nutrition and high water stability, can be used for replacing cured fodders, can be prepared and popularized under simple processing conditions and is capable of reducing energy consumption of production; the formula is optimized, the compound adhesive is added and a simple curing process is adopted, so that the fodder is capable of solving the problems of low water stability, low efficiency of feed utilization, higher bait coefficient and water pollution of the present green crab fodder; the technology according to the invention is simple and the prepared fodder, compared with the traditional fodder, is more environment-friendly and is higher in use ratio.
