🚨Paper alert!
🐟 What do young Atlantic bluefin tuna eat in the Mediterranean?
📍 We studied their diet in the Gulf of Valencia over 30 years.
🔍 Have their habits changed? Are they affecting sardines and anchovies?

👇 Let’s dive in!

1️⃣ What do fish do when they see a human underwater?

We studied how white seabream (Diplodus sargus) react when approached by a snorkeler or a spearfisher. Do they flee sooner when alone or in a group? 🤿

👀 Are fish afraid of us?
The #HumanFear project, led by @valeriosbra.bsky.social, investigates if activities like snorkeling and recreational spearfishing 🤿alter fish behavior and, at the same time, the dynamics of marine ecosystems.

🛥️What does environmental stewardship mean? 🤔
A new study shows that differing definitions can cause conservation conflicts. Using thought experiments and the Delphi process, researchers highlight how understanding these differences improves management.

🎣Our researcher @valeriosbra.bsky.social took his session on the ecology and social aspects of spearfishing at
Università di Pisa.
Since 2020/21, he’s shared his knowledge in this course by Prof. Ferruccio Maltagliati.

Our last contribution to understand how fish adjust their behaviour to underwater human presence. It seems that fieldwork alone is not sufficient to fully reveal the role of group size in modulating flight initiation distance 🤔 @imares-group.bsky.social
