Juvenile Handling

This video consists of X section showing different aquaculture operations where juvenile fish are handled for husbandry purposes. The first example is juvenile sorting and grading in a pompano hatchery. This takes place in large tanks which appear to be up to 1 meter deep and aerated. Small juvenile fishy are concentrated in shallow plastic baskets with holes or slots that would allow the smallest fish to escape. Workers are passing the basket into and out of the water to flush out any smaller fish or particles.  

The second example are slightly larger juvenile grouper which are shown being introduced to a similar grading basket within a large tank from a fine-mesh dip net. Smaller juveniles are then shown being transferred between grading baskets using an enamel metal bowl.

The third example shows juvenile seabass being managed within smaller net pen structures within a large and probably lined pond. There is significant water movement and foaming suggesting fresh and possibly aerated water is being supplied into the pens during the operation. The fish are being removed from the pens using hand nets into blue plastic bowels without water from where they are examined by the farm workers and some removed and thrown to an adjacent pen. 

The fourth example is catfish fingerlings held in a fine mesh net where they can be lifted out of the water and a hand net used to remove them.

The fifth example shows very concentrated fingerling carp in a large white bucket-like container being poured into a larger plastic barrel type tank. Both containers have water. There is then a brief clip of the fish being transferred from a hand net into the white backet at the pond bank. 

The sixth example is snakehead fingerlings being transferred by hand net into a large white bucket type container that is sitting on an electronic scale to measure weight. The bucket contains no water and the video shows two full nets of fish added to the bucket.

The final example is tilapia fry being held in a wire mesh basket in the shallow part of a tank. The fish are concentrated and swimming actively and some smaller fish can be seen to escape and swim away at the start of the segment.
