Murray cod are Australia's largest freshwater fish and, as a freshwater person, I kinda relate to it.
In particular, the line about the skeleton prompts me to share this remarkable discovery:
These fish are known to be protective fathers and travel long distances, like salmon, to return to their home to spawn.
They nearly were made extinct by large-scale fishing and, in recent years, have become an aquaculture crop.
If I drive west there are many breeding ponds where cod are grown for meat, and if I drive east there's the John Lake Centre where the techniques for propagation were documented.The story is that Lake was told a cod had taken residence in a neighbouring dam, where he found it used a 44-gallon drum like it was a treehollow for spawning young.
Anyway, I can talk about cod for a while since I put together an exhibition about them.
