1. Juvenile Bao Nurturing (1) Feed: The juvenile Baoqiao is about 1.85 millimeters long, which means that the first breathing hole is completed. Growing to a shell length of 5 mm, the staple food is benthic diatoms, but young seaweed can also be eaten. Therefore, it can be fed in a timely manner.
(2) Density: Juvenile abalone should adjust the stocking density timely. When the shell length is within 2.5mm, the cultivation density is 0.3-0.5/cm2; when the shell length is within 3mm, the cultivation density is 0.1-0.3/ Square centimeter; when the shell length is within 5mm, the incubation density is 0.1/cm2.
(3) Change of water volume: in the case of small production, taking into account economic efficiency, the water exchange volume is 4 to 6 times, and the survival rate of 70% to 80% is sufficient. Of course, if conditions permit, the water can be changed 9 times and the survival rate can reach 97%.
2. Peeling (1) Drug soaking Anesthesia, peeling: The juvenile abalone with a shell length of 5 mm or more was transferred to a young abalone.
(2) Other stripping methods Seawater impact: It is suitable for stripping the young abalone attached to the pool wall. It uses a pump with a flow rate of 22 liters per minute to flush the young abalone attached to the pool wall. At the same time, a cage is set at the drain outlet. Water enters the cage and can be collected.
Temperature Difference Stimulation: The attachment plate with a childbirth abalone is soaked in seawater of two different temperatures. The childbearing abalone is stimulated by a temperature difference, and it falls off. However, the range of temperature difference should not be too large, otherwise the mortality rate will be high.
The above various stripping methods, relatively speaking, the manual stripping method is safe and effective. Because of the use of a brush or a sponge, it is not easy to cause damage to the hatchery.
Whether it is to take drug anesthetic stripping or seawater impact stripping, it is necessary to use different screen mesh screens to nest together when the narcotic anaesthesia has not returned to normal, and move them back and forth in the water. Junior Bao, in order to facilitate the development of grading.
3. Young calves cultivating (1) Baits: Incubation stage of young calves, strong feeding power, large amount of bait requirements, and a wide range of bait types. Therefore, it is necessary to feed kelp such as kelp, canola, and river fence. In the initial stage, the algae can be processed into fresh algae and fresh algae to facilitate feeding and gradually increase the amount of feeding. Appropriate supplement powdery, flake-like food.
(2) Increase shading equipment: At this time, the reaction habit of juvenile abalone to light has shifted from light orientation to light. Therefore, shading equipment should be increased accordingly to control the light intensity, and the light should not be too strong.
(3) Stocking density: The stocking density of young hatchlings should not be too large. For cage culture, 6,000 juvenile hatchlings with a shell length of 5 mm can be stocked per square metre of water; 4000 larvae are cultured on a square-brick basis. If it is a young abalone with a shell length of 10 to 20 millimeters, it can stock 2,000 to 3,000 fish.
(4) Inflation of flowing water: about 6 millimeters in length in juvenile abalone shell, the amount of water flow is not less than 4-6 times of cultivated water body, the aeration rate per minute is still 1% to 1.5%, so that the dissolved oxygen in cultivated water body is not low At 5 mg/l.
(5) Young hatchery cultivation methods: There are mainly two methods of cage cultivation and square brick cultivation.
Cage cultivation: Hang cages in pool water, and place a horizontal corrugated plate (made of dark hard plastic sheet) in the cage. The size of the cage is generally 1 meter, 0.6 meter, and 0.3 meter. Polyethylene is used. Made of mesh sheet, the corrugated board has a round hole with a diameter of 3 cm, making it easy for young cubs to crawl up and down.
Corner brick cultivation: Four corner bricks are made of cement mortar, 30 centimeters long, 3 centimeters thick, and 4 centimeters long. They are made of black hard plastic. Place 15 to 18 bricks per square meter, spaced 7 to 10 cm.
(6) Routine management: In the cultivation, the water body should be exchanged, and the pool should be cleaned 2 or 3 times a week to remove the residual baits and dirt attached to the base and the bottom of the pool. Young calves often climb out of the water and should move into the water at any time to avoid death. If there are a lot of young hatchlings crawling near the waterline, they should check and change the water and increase the amount of aeration.
Bee Pollen is the pollen ball that has been
packed by worker honeybees into
pellets. Bee bread is also the bee pollen with added nectar and enzymes and
stored in brood cells, chambers of honeybees or of wood
and mud created by female ground-nesting when the pollen ball is complete, a
single female lays an egg on top of the pollen ball, and seals the brood cell. Pollen
balls are harvested as food for humans. Bee pollen is sometimes referred to as ambrosia.,
whereas with honey bees, the thing to keep in mind is that the forager bees
that gather pollen do not eat it themselves, since when they transition to
foraging, they stop producing the proteolytic enzymes necessary to digest it.
So the foragers unload the pollen they`ve gathered directly into open cells
located at the interface between the brood and stored honey, creating a typical
band of what is called beebread - the substance which is the main food source
for honey bee larvae and workers.
Foraging bees
bring pollen back to the hive, where they pass it off to other worker bees, who
pack the pollen into cells with their heads. During collection and possibly
packing, the pollen is mixed with nectar and bee salivary secretions. Bee
pollen is the primary source of protein for the hive. This method of packing
can be seen in the bee species
Composition
Like honey and propolis,
other well-known honey bee products that are gathered rather than secreted
(i.e., in contrast to royal jelly and beeswax),
the exact chemical composition depends on the plants the worker bees gather
the pollen from, and can vary from hour to hour, day to day, week to week,
colony to colony, even in the same apiary,
with no two samples of bee pollen exactly identical. Accordingly, chemical and
nutritional analyses of bee pollen apply only to the specific samples being
tested, and cannot be extrapolated to samples gathered in other places or other
times. Although there is no specific chemical composition, the average
composition is said to be 40-60% simple sugars (fructose and glucose), 20-60%
proteins, 3% minerals and vitamins, 1-32% fatty acids, and 5% diverse other
components. A study of bee pollen samples showed that they may contain 188
kinds of fungi and
29 kinds of bacteria. Despite this microbial diversity, stored pollen
(also called bee bread) is a preservation environment similar to honey, and
contains consistently low microbial biomass.
Use
as a health supplement
Bee pollen has been touted by herbalists as
a treatment for a variety of medical conditions but there is scientific
controversy with some saying it does not have any health benefits whilst others
claiming it does. Nonetheless there seems to remain the potential risks of
consuming bee pollen that include contamination by fungal mycotoxins,
pesticides or toxic metals. Bee pollen is safe for short term use, but for
those with pollen allergies, allergic reactions may occur (shortness of breath, hives,
swelling, and anaphylaxis). Bee pollen is not safe for pregnant women and
should not be used during breastfeeding. The Food and Drug Administration has
warned against the use of some bee pollen products because they are adulterated
with unapproved drugs including sibutramine and phenolphthalein.
