In a specific example, different feed large yellow croakers were fed:
cultivation experiment
Before the beginning of the formal culture experiment, pseudosciaena crocea is temporarily cultured in a seawater floating net cage (4 multiplied by 8 multiplied by 4), and expanded commercial feed is fed to adapt to the environment and the feed. After two weeks, starving for 24 hours, selecting large yellow croakers which are strong and have regular specifications (the initial weight: 189.7 +/-0.64 g), randomly dividing the large yellow croakers into floating cages (2 multiplied by 2), feeding the large yellow croakers with 100 tails of each cage in 3 parallel cages corresponding to each feed twice a day, weighing and recording the number of dead fishes and the feed amount. During the culture period, the water temperature is 19.8-28.5 ℃, the salinity is 31.1-34.9, the dissolved oxygen is more than 6mg/L, and the culture period is 90 days.
Body colour measurement
After the culture experiment is finished and 8 o' clock in the evening, 9 fishes are randomly fished out from each net cage, and the body color of the large yellow croaker is measured at 6 different positions (back 1, back site 1, back 2, back site 2, tail, abdomen 1, abdomen site 1, abdomen 2, abdomen site 2 and abdominal bottom) by using a portable color difference meter (CR-400, Konika-Meinenda, Japan) under the condition of keeping out of the sun (the sites are shown in the following figure 1). L represents the brightness value, a represents the red value, b represents the yellow value, measured according to the rules of the international commission on illumination CIE (cie.1976). The larger the value of L, the brighter the color, otherwise, the darker the color; the larger the value of a, the more red the color is, otherwise, the more green the color is; a larger value of b indicates a more yellow color, otherwise the color is more blue. The measurement results are shown in Table 3.

Figure BSA0000250037550000071
Note: the data are represented as: and (4) average value. Different letter designations indicate significant differences (P < 0.05).
As can be seen from the above experimental results, the addition of astaxanthin and lutein to the mixed feed containing Clostridium ethanolicum protein can affect the body color of large yellow croaker.
Wherein, aiming at the 1 site on the back of the large yellow croaker, the addition of lutein can obviously improve the brightness value L and the yellow value b (P is less than 0.05) compared with the group without pigment; the addition of astaxanthin slightly increased the yellow value b, but there was no significant difference compared to the group without addition and the group with addition of lutein.
Aiming at 2 sites on the back of the large yellow croaker, compared with a group without pigments, the yellow value b (P is less than 0.05) can be obviously improved by adding lutein; the addition of astaxanthin slightly increased the yellow value b, but there was no significant difference compared to the group without addition and the group with addition of lutein.
Aiming at tail sites of the large yellow croakers, compared with a group without pigments, the yellow value b (P is less than 0.05) can be obviously improved by adding lutein; the addition of astaxanthin slightly increased the yellow value b, but there was no significant difference compared to the group without addition and the group with addition of lutein.
Aiming at the abdominal 1 site of the large yellow croaker, compared with a group without pigments, the yellow value b (P is less than 0.05) can be obviously improved by adding lutein; the addition of astaxanthin slightly increased the yellow value b, but there was no significant difference compared to the group without addition and the group with addition of lutein.
Aiming at 2 sites of the abdomen of the large yellow croaker, compared with a group without pigment, the addition of lutein obviously reduces the brightness value L (P is less than 0.05) and obviously improves the yellow value b (P is less than 0.05); compared with the lutein group, the red value a (P < 0.05) is obviously improved by adding the astaxanthin, and compared with the group without the pigment, the yellow value b (P < 0.05) is obviously improved by adding the astaxanthin.
For the abdominal bottom part of the large yellow croaker, compared with the group without the added pigment, the added astaxanthin or the added lutein obviously reduces the brightness value L, obviously increases the red value a, obviously increases the yellow value b (P < 0.05), and slightly increases the yellow value b by adding the astaxanthin, but has no obvious difference compared with the group without the added pigment and the group with the added lutein.
According to the analysis of the above experimental results, the addition of 80mg/kg astaxanthin to the compound feed containing 22.4% clostridium ethanolate protein can obviously improve the red value a of the abdomen 2 and the bottom of the abdomen of the large yellow croaker, obviously improve the yellow value b of the abdomen 2 and obviously reduce the brightness value L of the bottom of the abdomen. The yellow value b of the back 1, the back 2, the tail, the abdomen 1, the abdomen 2 and the abdominal bottom of the large yellow croaker can be obviously improved by adding 80mg/kg of lutein, the brightness value L of the back 1 is obviously improved, the brightness value L of the abdomen 2 and the abdominal bottom is obviously reduced, and the red value a of the abdominal bottom is obviously improved.
Meanwhile, although the body color of the large yellow croaker can be improved by adding the astaxanthin and the lutein into the basic feed, the body color improvement effect of the lutein is more obvious. Lutein is the preferred choice in view of practical production costs.
Particularly, the clostridium ethanolate protein is a novel mycoprotein with extremely high nutritional value, and as a novel protein source, a few studies show that the clostridium ethanolate protein can replace part of fish meal in certain carnivorous fish compound feeds, but the studies on replacing the fish meal in large yellow croaker compound feeds are rarely reported. Astaxanthin and lutein belong to carotenoid, aquatic animals cannot synthesize the carotenoid, and the body color of large yellow croaker can be improved by adding the astaxanthin or the lutein into feed.
