The fish research programme introduces Estonian fishery and fish species. The main objects of study are the fish of Lake Ermistu: perch, roach, bream, pike. In addition, major sea fish are also studied: European sprat, Baltic herring, zander, garfish; permanent slides about the structure of fish are examined.
Snow and ice biota
The formation of snow and ice is studied. If possible, snowflakes are examined under a microscope, original photographs related to the topic are viewed, the thickness and density of snow is measured on the field. In addition, ice is drilled and ice samples are examined (transparency, colour, etc.).
Fishing for beginners
We learn about the rules of recreational fishing, and get to know the most common fishing tackle and techniques, as well as safety techniques. We conduct simpler nature observations: weather, water temperature, oxygen content, transparency, connection to fish.
The programme provides an overview of all aquatic plants – from microscopic plankton to flowering plants. Cyanobacteria that affects the quality of bathing water is examined from fresh material and previously collected samples. Swimming safety is also explained.
The concept of an introduced species is clarified. The increase in the frequency of introduced species, the impact of introduced species on native species, their economic benefits and harms are discussed.
Fauna of the body of water
During the excursion to the water body, the general condition of the water body is studied, simpler measurements are made (O2, pH, transparency, temperature). The suitability of the water body as a living environment is assessed and the rules of environmentally friendly collection are explained.
