While γ-aminobutyric acid (GABA) promotes nutrient accumulation in green microalgae, its effects on marine diatoms—critical aquaculture feed—remain understudied. Understanding the physiological response of diatoms to exogenous GABA is vital for optimizing high-quality feed production. In this study, we investigated the impact of GABA on diatom growth, photosynthetic performance, proximate composition (lipids, proteins, carbohy...

The last 30 years have witnessed the degradation and loss of function in the ecosystem of the Bohai Sea, China. Great efforts, such as artificial reefs, have been used to restore the ecosystem of the Bohai Sea in recent years. In this study, we examined the seasonal variation of food webs in artificial reefs of Juehua Island by the Ecopath model. Results showed that the number of species, range of trophic level, energy cycle p...
