Embodiment 1
[0026] The culture medium is natural seawater, and after the seawater is filtered, boiled and sterilized, and cooled to room temperature, it is placed in a high-temperature sterilized vessel for use.
[0027] Collect mature individuals of reticulated barnacles, and select larger individuals when sampling, and the appearance is intact.
[0028] Dissect adult barnacles, select mature fertilized egg pieces and put them into a 500ml beaker equipped with sterilized seawater for hatching (the 500ml beaker selected in this embodiment refers to the beaker used when collecting barnacle egg pieces and hatching nauplii, because the beaker is too large. Easy to operate, but the beaker is too small and there is little water, which is not conducive to separating the unhatched egg masses from the hatched nauplii, the same below), and then move the collected nauplii into a 1000ml beaker to cultivate according to the following steps:
[0029] (1) After the eggs of netted barnacles hatch into n...
Embodiment 2
[0035] The culture medium is natural seawater, and after the seawater is filtered, boiled and sterilized, and cooled to room temperature, it is placed in a high-temperature sterilized vessel for use.
[0036] Collect mature individuals of reticulated barnacles, and select larger individuals when sampling, and the appearance is intact.
[0037] Adult barnacles were dissected, mature fertilized eggs were selected and incubated in a 500ml beaker filled with sterilized seawater, and then the collected nauplii were cultured according to the following steps:
[0038] (1) After the eggs of reticulated barnacles hatch into nauplii, seawater is used as the culture medium (1000ml), and subcordate flat algae is the bait (2.5~3.0×105 cells / ml), cultured at room temperature (25-28°C) in a dark environment; the density of larvae in seawater is 1-2 / ml;
[0039] (2) The beaker containing the barnacle larvae was subjected to natural light for 1 hour every morning and evening;
[0040] In the ...
Embodiment 3
[0044] The culture medium is natural seawater, and after the seawater is filtered, boiled and sterilized, and cooled to room temperature, it is placed in a high-temperature sterilized vessel for use.
[0045] Collect mature individuals of reticulated barnacles, and select larger individuals when sampling, and the appearance is intact.
[0046] Adult barnacles were dissected, mature fertilized eggs were selected and incubated in a 500ml beaker filled with sterilized seawater, and then the collected nauplii were grouped and cultured according to the following steps:
[0047] (1) be divided into four groups and carry out, after the ovum hatching of reticulated barnacles is all treated as nauplii in the early stage, take 1000ml seawater as culture medium, subcardioid flat algae as bait, put nauplii into incubator Cultivate in a dark environment at a constant temperature of 29-31°C; the density of larvae in seawater is 2 / ml;
[0048] The difference between the four experimental gr...
