Based on the given pictures, guess the tools being shown or described. unlocking content area vocabulary. Salinity, the concentration of dissolved salts in a solution. Versatile describes something or someone that is capable of adapting or being used in various ways or for various purposes. Brails typically refers to ropes or lines used to control the edges or corners of a sail. Substrate. A material or surface on or in which an organism lives, grows, or is attached. Sediment. Solid particles that settle at the bottom of a liquid or are deposited on the surface of a solid. Tools and equipment used in aquaculture. Tools and equipment refer to the various instruments, machinery and devices used in the management, maintenance and operation of aquaculture facilities. Water pump horizontal and vertical centrifugal pumps are typically used for recirculation purposes. Their working principles are similar and the main difference between these aquaculture pumps is the shaft's position. Laboratory thermometer. These are essential tools in aquaculture for monitoring water temperature, ensuring optimal conditions for aquatic organisms, conducting research and maintaining quality assurance in laboratory settings. Salinometer or refratoter. Valuable tool for measuring salinity accurately and efficiently. Providing essential information for a wide range of scientific, industrial and environmental applications related to aquatic ecosystems and water management. Dissolved oxygen meter play a vital role in water quality monitoring and management providing essential data for ensuring the health and sustainability of aquatic environments and supporting various industries and research activities. PH meter valuable tools for measuring and monitoring pH accurately and efficiently. Providing essential information for a wide range of scientific, industrial and environmental applications. SEI disk measurements are commonly used by scientists, environmental researchers and citizen scientists for monitoring water quality in lakes, rivers and coastal areas. Activity concept mapping tools and functions. Draw a simple map linking each aquaculture tool to its function. Example image small sample concept map. Example net right pointing arrow catching fish. Why are aquaculture tools important in fish production?
