The elver stage lasts about three to twelve months. Elvers that enter fresh water may spend much of this period migrating upstream. Elver influx is linked to increased temperature and reduced flow early in the migration season, and to tidal cycle influence later on. [11] 5. Yellow eels: This is the sexually immature adult stage of American eel.
Tesch — like Schmidt — kept trying to persuade sponsors to provide more funding for expeditions. His proposal was to release 50 silver eels from Danish waters, with transmitters that would detach from the eels each second day, float up toward the surface, and broadcast their position, depth, and temperature to satellite receivers.
European eels live through 5 stages of development: larva (leptocephalus), glass eel, elver, yellow eel, and silver eel.Adults in the yellow phase are normally around 45–65 centimetres (18–26 in) and rarely reach more than 1.0 metre (3 ft 3 in), but can reach a length of up to 1.33 metres (4 ft 4 in) in exceptional cases.

The term "eel" is also used for some other eel-shaped fish, such as electric eels (genus Electrophorus), swamp eels (order Synbranchiformes), and deep-sea spiny eels (family Notacanthidae). However, these other clades , with the exception of deep-sea spiny eels, whose order Notacanthiformes is the sister clade to true eels, evolved their eel ...

Temperate eels migrate on average for approximately 6–10 months, while tropical eels undergo shorter migrations between approximately 3–5 months on average. [23] The European eel ( A. anguillidae ) has one of the longest migrations of all freshwater eels, migrating up to 6000 km (over 3700 miles) in a single migration loop.
