example 1

[0039]In August 2012, we conducted a golden squid breeding experiment at Qingdao Jinshatan Aquatic Development Co., Ltd. The bait is the compound feed prepared by the project team, which is in the shape of thin strips, with a length of 2-6cm and a diameter of 0.2-0.3cm. The formula is: 50% shrimp meal, 6% fish meal, 7.5% soybean meal, 7.5% peanut meal, 3 %, feed yeast 6%, starch 8%, fish oil 4%, choline chloride 0.7%, biological enzyme 4%, lecithin 0.3%, compound vitamin additive 2%, compound mineral additive 1%. At the beginning of the experiment, the golden squid was 80 days old, with a carcass length of 4.2 cm and a body weight of 65 g. The bait was fed twice a day at 7:00 am and 4:00 pm respectively, and the amount of each feed was 2% of the body weight of the golden squid. The water used for breeding is seawater with secondary sand filter, the water temperature is 22-23°C, the air is continuously inflated, and the light is natural light. After feeding the compound feed ...

example 2

[0041] In November 2011, we conducted a winter breeding experiment of golden squid at Tianjin Xinyongfeng Aquaculture Co., Ltd. The bait is the compound feed prepared by the project team, which is in the shape of thin strips, with a length of 6-8cm and a diameter of 0.5-0.6cm. The formula is: 50% shrimp meal, 6% fish meal, 7.5% soybean meal, 7.5% peanut meal, and 3% seaweed meal , Feed yeast 6%, starch 8%, fish oil 4%, choline chloride 0.7%, biological enzyme 4%, lecithin 0.3%, compound vitamin additive 2%, compound mineral additive 1%. At the beginning of the experiment, the golden squid was 180 days old, with a carcass length of 15.2 cm and a body weight of 410 g. The bait is fed twice a day, at 8:00 am and 5:00 pm respectively, and the amount of each feed is 2 to 3% of the body weight of the golden squid. The water for breeding is seawater blended with heavy brine and geothermal fresh water, the water temperature is 20-21°C, the salinity is 27-29, the aeration is continuou...

Abstract

The invention relates to artificial compound feed formula for sepia esculenta cultivation and a feed. The artificial compound feed formula for sepia esculenta cultivation comprises the components of shrimp meal, fish meal, bean pulp, peanut pulp, seaweed meal, feed yeasts, starches, fish oil, choline chloride, biological enzymes, lecithin, compound vitamin additives and compound mineral substance additives. The artificial compound feed formula disclosed by the invention provides the nutrients, namely proteins, fats, carbohydrates, trace elements, vitamins and other modifying agents and the like through multiple feed sources aiming at the nutritional requirements of sepia esculenta, ensures that nutrition proportion is balanced and can meet the nutritional requirements of the normal growth of the sepia esculenta; the feed disclosed by the invention is in the shape of a thin strip and simulated into the shapes of live baits and chilled fresh baits, thereby ensuring that young sepia esculenta is easy to transform from eating the chilled fresh baits to eat the artificial compound feed; according to the invention, the cultivation cost spent by feeding the feed produced through the artificial compound feed formula disclosed by the invention is reduced by 40% compared with the cultivation cost spent by feeding the live baits, and the survival rate is enhanced by 30% compared with the survival rate achieved by feeding the chilled fresh baits.

Description

Technical field: [0001] The invention belongs to the field of aquatic feed, and in particular relates to an artificial compound feed formula and feed for growing golden squid. Background technique: [0002] Golden squid used to be one of the four traditional fisheries in my country and was an important breeding target, but its resources have been depleted since the 1980s. In response to the urgent need to restore the resources of golden squid, the Yellow Sea Fisheries Research Institute has been conducting research on golden squid seed breeding and multiplication breeding technology since 2005. its industrial application. Because golden squid has the characteristics of large size (average weight 700g), rapid growth (it can be launched in the market after 9 months), short life cycle (one year), rich nutrition, and obvious migration rules, etc., the prospect of increasing breeding is broad. At present, golden squid farming The scope has been extended to the marine aquacultur...
