Molecular and biochemical effects on metabolism and immunity of Hyriopsis cumingii fed with four different microalgae

Hyriopsis cumingii has attracted attention because of its pearl production performance and water purification capacity. Realizing sustainable industrialized culture H. or applying it to bivalve biomanipulation for controlling eutrophication needs urgent studies about the selection suitable algae effects different microalgae on mussel physiology. To contrast molecular biochemical high-quality microalgal diets ( Chlorella vulgaris , Navicula pelliculosa Cyclotella sp.) with toxic Microcystis aeruginosa metabolism immune physiology levels related enzymes genes were analyzed during 28-day exposure period. Results showed that sp. diet could significantly p < 0.05) maintain higher metabolic (glutamic oxaloacetate transaminase (GOT), glutamic pyruvate (GPT), kinase (PK), hexokinase (HK)) (CPT1 LDLR). C. N. treatments reduced activities these parameters. The M. treatment enhanced (alkaline phosphatase (AKP), superoxide dismutase (SOD), catalase (CAT)) (HcIL-17 IAP) day 1 7, there was a significant reduction 28. suggested followed by caused disorders, injury, poor physiological status. study practical significance in cultivation provides theoretical basis eutrophic water.
