Amino acids have a strong stimulatory effect on fish's sense of smell and taste. L-amino acids are effective attractants for aquatic animals, and their D-amino acid attraction is weak. The effect of the same attractant on the different growth stages of different animals or the same animal is different or even completely different. Amino acid mixtures are more effective than single amino acids.
2. Sulfur-containing organic matter? Cave DMPT? Snow
DMPT. Bp dimethyl-p-propionate is a potent aquatic animal attractant. DMPT is the most effective lure agent and can increase the biting frequency of fish. There may be special DMPT receptors in the fish's taste and olfactory organs.
3. Nucleic acids
Inosinic acid is the most effective nucleotide, but its activity is affected by inosine, adenosine diphosphate and creatine.
4. Betaine
Betaine is a glycine trimethyl lactone extracted from sugar beet processing by-products. Betaine is one of the stimulants of animal taste. Betaine's attracting action also shows synergistic effect with some amino acids, which not only makes the fish's taste perception of betaine, but also enhances the fish's taste perception of amino acids, thereby enhancing the attracting effect of amino acids.
5. Animals and plants and their extracts
The use of earthworm as a lure can increase food intake, feed frequency, and weight gain of shrimp. With the increase in the amount of barium added to the feed, the degree of feeding preference of Scutellaria baicalensis has gradually increased. It has been speculated that the decoction of the alfalfa slurry may be related to lysine, histidine and glycine because of the high content of these amino acids in alfalfa. Some of the plants and animals were chemically extracted and then studied. The results showed that certain components of the extract could improve the palatability of the bait. Currently, Cladocera, Chironomid larvae, scorpions, oysters, and squid have been confirmed. The larvae of bamboo, mackerel, juvenile fish, prawn, crab, clove, snail, cocoon, cockroach and other animals and plants and their extracts may be due to their large amounts of amino acids and nucleotides.
Garlic contains a unique allicin, with a spicy taste, adding 0.5% to 3% of allicin powder to the salmon diet. Its strong odor promotes the fish's feeding activities. Feeding squid with garlicin (100 mg/kg body weight) increased the survival rate, weight gain rate, and feed efficiency by 1.4%, 18.4%, and 10.3%, respectively, compared to the control group.
6. Herbs
Some Chinese herbal medicines not only have a strong attracting effect, but also have the effect of promoting the growth of fish and enhancing the resistance to disease. According to the experience of the Chinese folk folk “Awe†used as a fishing bait, the researchers used the chemical composition and similar grass as bait to catch the yellow cricket. The effect was very obvious.
Vaccine For Prevention Of Rabies
Rabies vaccine is used in two ways. Rabies vaccine is given to persons who have been exposed (eg, by a bite, scratch, or lick) to an animal that is known, or thought, to have rabies. This is called post-exposure prophylaxis. Rabies vaccine may also be given ahead of time to persons who have a high risk of getting infected with rabies virus. These persons include veterinarians, animal handlers, or travelers who will spend more than 1 month in countries having a high rate of rabies infection, and persons who live, work, or take vacations in wild areas of the country where they are likely to come into contact with wild animals
