The Effect of Temperature on the Physiological Condition and Immune-Capacity of European Lobsters (Homarus gammarus) During Long-Term Starvation
Decapod crustaceans, such as those from the Homarus genus, are key benthic representatives that support very valuable fishing and aquaculture industries. Those commercially caught, such as the European lobster (H. gammarus) can be stored in live facilities for short (a few days) to long periods (up...

Decapod crustaceans, such as those from the Homarus genus, are key benthic representatives that support very valuable fishing and aquaculture industries.

Conditions in captivity are not standardized, including holding temperatures or feeding regimes. Herein, the physiological condition during long-term starvation (24 weeks) in H. gammarus was assessed at three temperatures (4, 8, and 12°C). Our results indicate that, H. gammarus have the capacity to endure long-term starvation. Principal component analysis (PCA) of measured parameters showed two main components (Eigen value >1).
