More than 43,000 chicks were distributed in recent months, and 10 million fish larvae were introduced into local waters.

It is mainly used as an energy-rich food source for fish larvae and rotifers.

As a result, there are less prey for the fish larvae to feed upon, and the success of a recruitment event in severely diminished.

Like the sticklebacks, they feed on small invertebrates and fish larvae.

Newly hatched fish larvae are about 2.32 mm long and appear translucent.

Leptocephali differ from other fish larvae is in their development.

They then become pelagic and join other fish larvae in the "ichthyoplankton community".

Test subjects include tadpoles, fish larvae and the astronauts themselves.

Two examples are fish larvae and sea stars (also called starfish).

Like sticklebacks, its feeds on small invertebrates and fish larvae.
