Sea runners - Early Season Excitement - Christopher Bassano

Presented from Issue 100
Considering the world class quality of our sea trout fishery, these fish are not sought after by enough anglers. Sea runners live in the salt water and run up our estuaries and rivers from the start of August to the middle of November. At this time of the year, they are here to eat the many species of fish that are either running up the rivers to spawn or are living in and around the estuary systems. Trout, both sea run and resident (Slob Trout) feed heavily on these small fish which darken in colouration as they move further into fresh water reaches.

The majority of these predatory fish are brown trout with rainbows making up a very small percentage of the catch. They can be found all around the state but it would be fair to say that the east coast is the least prolific of all the areas. They still run up such rivers as the Georges (and many others) but their numbers along with the quality of the fishing elsewhere make it difficult to recommend the area above the larger northern, southern and western rivers.

Awesome find in the Derwent estuary.

Kevin Blackwell recently discovered this oarfish washed ashore under the Tasman Bridge. It weighed 20 kilos and measured 2.2 metres in length. Kevin donated it to CSIRO in Hobart. Below are the details from John Pogonoski to Kevin.

 

Hi Kevin
We thawed the oarfish yesterday, took photos and confirmed the identification (scientific name Regalecus glesne).

The below link has a map of the records from Australian waters (where a specimen exists in a fish collection – 37 records + this one). It  was only the 4th specimen in the CSIRO collection, so it will be retained in the collection. There are some differences in fin ray counts between your specimen and what I have found documented in fish books, but can’t take the identification any further until more information is published or until we get genetic results (which will take a few months).

Anyway, we really appreciate you donating the specimen to the CSIRO collection.

 

Cheers
