Hundreds of Trevally Shelter in the Shade

Hiding in the shade of the Omaha jetty floating pontoon this afternoon were hundreds of trevally of all sizes. They were accompanied by smaller numbers of parore and mullet, all station-keeping under the pontoon in the outgoing current.

Trevally

The water was beautifully clear about two hours after high tide, as there had been no rain and little wind for several days, the water offshore is really clear at present, and the vast numbers of cockles in the harbour would have finally “polished” the water of any remaining plankton and sediment.

I have seen trevally like this under the pontoon before, but they have usually stayed only a couple of days before moving on. But when they are there they are a lovely sight.

Today I just held my Go Pro camera in the water over the side of the pontoon, but it would be great to snorkel quietly over to the pontoon and take a closer look.

Kahawai school at Horseshoe Island channel

A school of several hundred young kahawai was seen in the channel behind Horseshoe Island on Saturday.  This was the largest number of kahawai I have seen in this area, and is a very encouraging sign.  There were also large numbers of adult parore, and the usual school of around 200 trevally which have grown since last summer.  There were no juvenile snapper, however, which were common in the summer but have departed for winter.

With 8 to 10 metres visibility, this is the clearest I have seen the harbour waters since the big cockle die-off in 2009.  There had been no rain or wind for several days, however, and the water on the coast is very clear at the moment too, which all helps the harbour’s water clarity.
