Tagging Very Small Fish: Two Effective and Low Impact Methods Identifying individuals over time and across contexts is essential in many scientific fields. There are a variety of well-established methods for uniquely marking individuals (e.g., visible implant e...

Find out more about tagging methods for tiny juvenile cichlids (Astatotilapia burtoni): tattoo ink injections and fine fishing line tags. Both are low-cost, safe, and don’t alter behavior! #Ichthyology #ResearchMethods

Turns out these sharks can make friends and have social lives, new study finds | CBC Radio New research is suggesting that not all sharks are the lone, cold, ruthless predators as many films so often depict them. Some species, it turns out, can even be friendly — at least among their own ki...

No such thing as a shark? Genomes shake up ocean predator’s family tree Sharks might not be a natural biological group, with most species potentially closer kin to rays than to an oddball group of sharks.

A hand-colored ed and yellow sea perch is in the foreground, while behind there is a black and white line drawing landscape with mountains, ocean, sailing ships, sea birds, etc., all miniature compared to the giant fish that dominates the scene.

Think this is a swallowtail sea perch, also known as a marine goldfish, with an early scientific name that didn't stick. From Ichthyology by Sir William Jardine, 1835. #fish #rarebooks #oldbooks #ichthyology
