12月9日(土)快晴
砂金浜の南東のはずれはバロン川支流のヨーキーズ分流。大雨のたびに上流から落ち葉や泥を運ぶので、砂金浜は鳴き砂ではありません。その代わり魚影が驚くほど豊富。波打ち際から20m先に鳥山が立ち、河口ではたくさんのボラが跳んでいます。よく見るとボラの前を無数の小魚が水面を跳びながら逃げ回っています。ボラの跳躍って捕食活動だったんですね。

Why mullets jump?
The end of south east of Golden Sand Beach is Yorkeys branch of Barron River. Every time when there is the heavy rain the river carries fallen leaves and the mud from the mountain, so Golden Sand Beach is not a weeping beach. On the other hand there are a lot of fish. You can see the gulls flying in flocks 20m beyond the beach and many mullets are jumping and dancing. Seeing carefully, countless tiddlers are also jumping to escape from the mullet. Jumping and dancing of mullet is the predation activity.
