春にメダカの卵をほったらかしにすると失敗する理由を解説します！

I'll share the methods I use every year for managing medaka eggs in early spring. "Eggs are laid, but they don't hatch." "They hatch, but the fry don't grow." These patterns are very common in spring. And the cause is almost always "water temperature." In summer, simply moving the spawning bed to a separate container is usually enough for hatching, but from late March to early May, when temperatures are unstable, leaving them alone won't work. This video carefully explains everything from the concept of accumulated water temperature to heater heating, egg collection, identifying fertilized eggs, methylene blue management, and heating methods using a plastic tub. ◆Recommended for: ・Those experiencing their first spring medaka breeding season ・Those who want to ensure the successful hatching of eggs from their cherished breed ・Those who are troubled by the fact that their fry don't seem to grow every year ------------------- 🔹Table of Contents🔹 00:00 Opening - Reasons why spring eggs don't hatch 01:43 Accumulated water temperature and the pitfalls of temperature fluctuations in early spring 06:05 My practical egg management method (egg collection, selection, and heating) 11:21 Summary -------------------
