The third lecture of the webinar Stickleback Day-2021 – “Stickleback in trophic chains”. It is dedicated to feeding of threespine stickleback and its’ role in feeding of some predatory fish in the coastal ecosystems of the White Sea.
Stickleback spends most of its life in the open waters. During spawning, it moves to the coast, where adult individuals spend a month or two, and juveniles – the first several weeks of their live. Thus, stickleback is included in coastal communities, being food for predators and eating plankton and benthos. The speakers are step by step discussing trophic connections of stickleback from the higher trophic level to the lower trophic level while sticklebacks are staying in coastal waters.
Lecturers – Anna Demchuk & Anastasiia Zelenskaia.
