Consider the following statements with reference to the Diadromous fis...
The study, published in the British Ecological Society’s Journal of Applied Ecology, found that MPAs designated to protect diadromous fish species did not align with their core habitats.
- These are those fish species which migrate between saltwater and freshwater environments.
- Some of the examples for diadromous fish: the allis shad (Alosa alosa), twait shad (Alosa fal- lax), Mediterranean twaite shad (Alosa agone) and the European eel (Anguilla anguilla) etc.
- In order to better understand these movements, scientists have classified these migrations into several categories.
- Anadromous fish: These are born in freshwater, then migrate to the ocean as juveniles where they grow into adults before migrating back into freshwater to spawn.
- Catadromous fish: These are born in saltwater, then migrate into freshwater as juveniles where they grow into adults before migrating back into the ocean to spawn.
- Amphidromous fish: These are born in freshwater/estuaries, then drift into the ocean as larvae before migrating back into freshwater to grow into adults and spawn.
- Potamodromous fish: These are born in upstream freshwater habitats, then migrate downstream (still in freshwater) as juveniles to grow into adults before migrating back upstream to spawn.
- Threats: Diadromous fish are sensitive to anthropogenic pressures. They are subjected to terrestrial, freshwater, and marine pressures such as agricultural and pollutant runoffs, habitat destruction, barriers to migration, fishing, bycatch, and climate change.
Hence both statements are correct.

Consider the following statements with reference to the Diadromous fis...
Diadromous Fish
Diadromous fish are fish species that migrate between saltwater and freshwater environments. These fish play a crucial role in the ecosystem as they transport nutrients between different habitats and contribute to the overall biodiversity of aquatic environments.
Examples of Diadromous Fish
- European eel and Allis shad are examples of diadromous fish.
- European eel, for example, spawns in the Sargasso Sea and migrates to freshwater rivers and streams to grow and mature.
- Allis shad migrate between saltwater and freshwater environments for spawning and feeding purposes.
Correctness of Statements
Both statements 1 and 2 are correct. Statement 1 accurately describes diadromous fish as species that migrate between saltwater and freshwater habitats. Statement 2 provides examples of diadromous fish, including European eel and Allis shad, which exhibit this migratory behavior in their life cycle. Therefore, the correct answer is option C - Both 1 and 2.
