जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Recorded from coastal waters at sea. Lacustrine, at depths greater than 30 m, in Lake Ladoga commonly at 50-150 m (Ref. 59043). Specimens measuring 36-40 cm are more than 5 years old. Spawns for the first time at 4-6 years (Ref. 59043). Spawns from the end of November to 20 December (Ref. 593). Oviparous (Ref. 205). Eggs are buried in unguarded nests (Ref. 205). Feeds on benthic invertebrates, especially gammarids, molluscs and insect larvae (Ref. 59043).
