First page of Mangolt's book from 1557
Just finished reading Gregor Mangolt's 1557 book "On the Nature and Traits of Fish — Especially Those Caught in Lake Constance". Fascinating early account including details on #parasites, #spawning #phenology #hybridisation, and spatial variability. #HistoryOfScience #LakeConstance
‘Heinrich Harder was a German artist and an art professor at the Prussian Academy of Arts in Berlin best known for his depictions of extinct animals.’ Wikipedia https://www.biodiversitylibrary.org/page/10028012#page/105/mode/1up

When the frogs turn up to spawn, it's not long until a Heron or two arrive to feed on them! (Lagan Meadows towpath, Belfast) #ukwildlife #amphibians #frogs #frogspawn #spawning #mating #northernireland #ireland

Two Common Frogs mating on a path at the side of the forest. The frogs are facing the camera with their left sides showing. The male is on top of the female and both heads are visible. They are on stone and the background is out of focus vegetation
A Common Frog poking its head out of water in a pond. The frog is facing the camera, the reflection of its head is visible in front of it. The water has a metallic appearance and is reflecting the grasses and reeds in the water. A small mound of frog spawn can be seen in the background
Two Common Frogs mating on a path at the side of the forest. The frogs are facing the camera straight on. The male is on top of the female and both heads are visible. They are on stone and the background is out of focus vegetation
Two Common Frogs with their heads poking out of the water; one is side on and the other is facing away. Their reflection are visible in front of them. There are grasses poking out of the after throughout and giving the water a green tinge.
Happy Valentines Day Everybody!
These Common Frogs have been getting into the spirit of things all week! Spawning season is well underway.

🔬Researchers found that broodstock conditioning and water temperature are key drivers of reliable #spawning, while high-energy diets significantly improve egg quality. Additionally researchers identified more than 40 #pathogens known to affect #kingfish.
I finally got to Carkeek Park to witness the homecoming of the Salmon. There were only a few stragglers on the last day of November, who were tired and stopped often to rest, like this one.

Digital art comic. Mischievous female imps perform a ritual using a woman with two braids in her hair. The woman has glasses and is naked except for her stockings. She's tied to the bed. The imps are about two feet tall with big hips and breasts. As a pentagram glows near the woman's pussy, two imp hands reach from within and open it. The ritual is completed as the newly summoned imp flies away through the air. The girl cries out in ecstasy. Her two captors look up with interest at the new imp.
A patreon sketch request I had around when I did the #TomeofImps sequence. The imps try summoning more of their kind rather than using conversion, for a change.

🪸 Handle with care, precious corals have arrived at SeaSim for #Spawnathon2025!
Our facility is designed to mimic the exact conditions that trigger #spawning These capabilities allow researchers to study #coral breeding, resilience, and restoration, supporting world-class reef science at #AIMS. 🌊
Ancient rhythms carried out every autumn since time immemorial ~ On this day last year Salmon return to spawn, one of nature’s wonders.

A brown bear splashes around while fishing in a river. The bear reaches into the water and catches sockeye salmon in Kamchatka, Russia.

Bolbometopon muricatum 隆頭鸚哥魚 is famous for its spawning aggregations—all the more impressive since it is the largest parrotfish species. For #SciArtSeptember #Spawning theme. #TaiwanFishes #台灣魚類 Day 15/30 (We're entering the second half now!!!) 🐡🦑🧪
An Atlantic sturgeon lying caught on a boat in the water next to a wooden jetty.
🌐🧪🦤 We reveal that #AtlanticSturgeon #Acipenseroxyrinchus produce low frequency thunder-like sounds associated with #spawning, similar to #lakesturgeon #Acipenserfulvescens. This finding lays the groundwork for passive acoustic monitoring of this endangered species. bit.ly/esr_58_1
Fig. 7. Conceptual model for the Antarctic battlefield where accumulation and concentration processes at the shallow-marine spawning ground may contribute to forming dense concentrations of belemnites. See Doyle and Macdonald: https://doi.org/10.1111/j.1502-3931.1993.tb01513.x
One in a million example of pabulite where belemnite which was bitten in half by a predator and subsequently dropped still preserved its arm crown and a prey item grasped within it. See: https://doi.org/10.1186/s13358-021-00225-z
In other cases, predators may be less successful in concentrating belemnite remains and (mass) #mortality at #spawning grounds after #reproduction may concentrate belemnite rostra. This is the basic of another model developed by Doyle and Macdonald (1993): doi.org/10.1111/j.15...
Fishing associations and landowners must spend large amounts to prevent escaped farmed #salmon in #Iceland from entering the rivers. It is essential to catch the #fish before #spawning.

An Alaskan Coastal Brown Bear walks through water that's up to its belly. It is looking towards the viewer. There are a few sprigs of grassy vegetation around the bear, indicating its coastal habitat.
