Device for comparing growth of coral with different flow rates

Abstract

The invention discloses a growth contrast device for corals with different flow rates, which comprises a water tank, a glass steel plate seat is transversely and fixedly laid in the middle of the water tank, a glass partition plate is vertically inserted in the middle of the glass steel plate seat, and the glass partition plate divides the middle of the water tank into a high flow rate area and a low flow rate area. A wave making pump is fixedly arranged in the water vat on the side corresponding to the head end of the high-flow-speed area, a high-speed area grid plate is transversely and vertically inserted into the glass steel plate base of the high-flow-speed area, and first containing coral tables are arranged on the rear side of the high-speed area grid plate at intervals. A low-speed area grid plate is transversely and vertically inserted into one side, close to the head end of the low-flow-speed area, of the glass steel plate base, second containing coral tables are arranged on the rear side of the low-speed area grid plate at intervals, and movable stones are placed in the water vat corresponding to the tail end of the low-flow-speed area. According to the growth comparison device for corals with different flow velocities, corals are placed on the two placing tables with different flow velocity areas to be cultured, then the influence of the flow velocities on physiological indexes such as the coral calcification rate and the photosynthetic efficiency can be measured, and the whole device is simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the technical field of marine coral growth experiment testing, in particular to a coral growth comparison device with different flow rates. Background technique [0002] As the ecosystem with the highest biodiversity in the ocean, the coral reef ecosystem not only nurtures many marine organisms, but also provides important ecological service functions for nature and humans, including maintaining biodiversity, coastal protection, fishery resources, tourism, science and education, etc. . However, coral reefs face threats including global climate change, the impact of human activities, pollution, and overfishing. Nearly half of coral reefs have been severely degraded, and two-thirds of coral reefs are seriously threatened. [0003] The effects of thermal anomalies on tropical corals are caused by a range of environmental factors that ultimately affect coral health and survival, an important one being the reef and current conditio...

Problems solved by technology

Fast water flow is well known to be beneficial for coral growth, but conclusive experimental evidence describing how water flow alleviates coral heat stress responses is still lacking
