ラスウナギを飼育した。結果を第１表に示す。
[Industrial Field of Application] The present invention relates to feed for glass eels. [Problems to be Solved by the Prior Art and the Invention] Glass eels are young eels, and as the demand for eels increases, feed for glass eels is becoming increasingly important. Conventionally used feed for glass eels includes minced fish and shellfish, such as sardines, mackerel, clams, and oysters, but this method has disadvantages in terms of cost, environmental protection, etc. as it causes a lot of feed to be lost. many. In addition, worms, which are natural feed, have been widely used, but since worms exist on the bottom of rivers, there are cases where filth, pathogens, etc. are introduced into the glass eel feed tank, and in this case, the glass eel can be wiped out, resulting in a large amount of damage. Damage may also occur.
On the other hand, in Japan, the amount of earthworms has been decreasing due to river pollution and other factors, and the current situation is that earthworms are being imported from foreign countries. Moreover, there are also problems with storage. The present inventor discovered the present invention after studying feeds for glass eels that do not have these drawbacks of currently used feeds for glass eels. [Means for Solving the Problems] That is, the present invention relates to a feed for glass eels whose main ingredient is ground raw squid meat. The squid used in the present invention is fresh or raw and refrigerated or frozen, and dried or freeze-dried squid is not very effective unless the amount of water added at the time of feeding is adjusted appropriately. The feed of the present invention is made by grinding raw squid meat, and preferably has an average diameter of 0.01 mm or less. If the diameter is larger than this, it will easily get stuck in the glass eel's digestive tract. Also, the moisture content of the feed is 65 to 85.
% by weight, preferably about 75-80% by weight is suitable. If the water content is lower than this range, glass eels with low digestive and absorption capacity will be burdened, and their growth will be poor. In addition, the adhesiveness becomes low and water tends to dissipate easily. The feed of the present invention has ground raw squid meat as its main ingredient, but also contains ingredients commonly used in fish feed, such as various vitamins, minerals, and binders such as pregelatinized starch, guar gum, sodium alginate, Xanthan gum, carboxymethycellulose, gluten, etc. may be added. When gluten is used, it may replace pregelatinized starch. The appropriate amount of the binder used is about 1 to 5% by weight based on the raw squid meat. 5
If it is more than % by weight, the resulting feed becomes hard and cannot be eaten by the glass eel, while if it is less than % by weight, the disadvantage is that the feed tends to dissipate into water. In producing the feed of the present invention, for example, raw squid meat is first ground into a paste, and then an appropriate amount of vitamins, minerals, and a binder are added to the paste and mixed well. I can do it. The obtained feed is stored, for example, by freezing. Furthermore, even if a small amount of krill is mixed into the feed of the present invention, excellent effects such as an improvement in the weight gain ratio can be achieved. [Example] Next, an example will be shown. Example 1 Raw squid meat was ground using a grinder to obtain meat with an average diameter of about 0.005 to 0.01 mm. The analysis values are 76.3% water, 20.3% protein, and fat.
The ash content was 1.8% by weight, and the ash content was 1.6% by weight. Its 9.61Kg
was thoroughly mixed with 90 g of vitamins (halvar vitamin), 100 g of minerals (pine column salt No. 185), 120 g of pregelatinized potato starch, and 80 g of guar gum. Test example Feed obtained in Example 1 14.85Kg (dry weight 3.713Kg)
Glass eels were raised using 20.7 kg of earthworms (dry weight: 4.14 kg). The results are shown in Table 1.
上述の第１表から分る様に、本発明の飼料は、
従来用いられているイトミミズに比べて、シラス
ウナギの嗜好性及び成長に劣らない効果を有す
る。その上、本発明の飼料は、イトミミズの有す
る前述の如き欠点例えば入手の困難、汚染などが
なく、それらの点を考慮すれば、イトミミズに比
較して優るとも劣らぬ飼料ということが出来る。
As can be seen from Table 1 above, the feed of the present invention has
Compared to the conventionally used worms, it has the same effect on the palatability and growth of glass eels. Furthermore, the feed of the present invention does not have the above-mentioned disadvantages of Japanese earthworms, such as difficulty in obtaining them, contamination, etc. Considering these points, it can be said that the feed is no less superior than that of Japanese earthworms.
