Herds of fish collect hundreds of fish stuck on the beach after the tide

Maybe the mackerel escapes predators and gets stuck in shallow pools.

Many people believe that it may be because dolphins are chasing them so they swim here.

Hundreds of fish swim in small puddles on the beach at St Ives, Cornwall (England), when the tide falls on September 24, AOL reported. Many people believe that it may be because dolphins are chasing them so they swim here.

Some fishermen take the opportunity to catch fish but only take the ones 30cm or more. Fishing smaller than this size is illegal. At Carbis Bay not far away, hundreds of other fish are also stuck on the beach just before dawn.

The representative of the Royal Society for Animal Protection (RSPCA) said that most of the fish will be rolled back to the sea at high tide. Such cases of shallow fish are quite unusual, occurring only about once a year along the coast.
