Pregnant Sharks and Rays Abort Offspring When Fished – Guest post by Kye Adams
Have you ever seen a viral video of a shark or ray giving birth (e.g. River Monsters)? Unfortunately, it turns out these videos have a pretty dark explanation: There’s a fairly high chance the female is actually aborting her pups due to the stress of being caught. Continue reading →
A prediction of the preferred environmental habitat for the range-shifting yellowtail kingfish (Seriola lalandi) for March 2008, based on a combination of preferences for sea surface temperature, current speed and sea surface height.
Curtis Champion is a PhD candidate at the Institute for Marine and Antarctic Studies – University of Tasmania. He stopped by the Fish Thinkers blog to give us a run down on some of the research he is working on.
Species on the move and a quick explainer about how range-shifts are commonly identified
Climate. Change. No doubt you’ve heard of the phenomenon. And while a small number of our political reps sporadically break into the headlines for criticising its reality, the global scientific community has been busy forging novel territory to understand its ecological consequences. This emergent field is most-commonly referred to as “species redistribution science” because plants and animals shifting where they live (generally towards the poles or up mountains) in response to changes in temperature is perhaps the most perceptible ecological effect of climate change.

The plan was to head to the mid stretches of the Thredbo River in the Snowy Mountains to try and fool some foot-long brown trout into eating a dry fly. But after a short walk to my favourite stretch of water the rain had set in making it almost impossible to spot my fly. A change in tactics was needed, so I tied on a heavy double nymph rig and attached a subtle indicator to fish some deeper runs.
Warm afternoons, insects hatching and brown trout looking to the surface for a feed – A couple of weekends ago my old man and I had a great weekend fly fishing the Snowy Mountains region. After mid-week snow and rain the creeks were running well and the trout eager for well-presented dry flies. Below are a handful of images from the trip…
It’s probably no real surprise that both Lac and I do a fair bit of fishing (some say too much). In the past we’ve documented what we’ve been catching on Instagram, but are often left with pictures from our fishing trips which end up clogging our hard drives. So this year we have created a “Fishing Journal” page on the blog to share some thoughts and pictures from our fishing adventures. Continue reading →
VEMCOs researchers map: ‘Help us help you collaborate with the best researchers in the world and let us “Put You on the Map”! Red pins represent studies using VEMCO products, the dark pins represent institutes’.
For those that have an interest in animal movement in the oceans, I’d like to draw your attention to a handy and interesting tool on the VEMCO website; the global tracking map. This tool Continue reading →
