Temperature requirements are suggested to be flexible. It has been found that American eels during elver stage can survive temperature as low as −0.8 °C (30.6 °F). Barila and Stauffer (1980) reported a final mean temperature preference at 16.7 °C (62.1 °F).
An elver pass or eel pass is a waterway modification constructed to mitigate the effects of obstructions, especially manmade weirs, on waterways, watercourses, ditches, drains, channels and flumes, on the movement of eels, fish and elvers (juvenile eels). Powerful swimmers, including salmon and sea trout, find it easy to pass through many ...
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 eel fishing season happens every spring and Maine is the only U.S. state with a significant, legal fishery for elvers. Last year's harvest was worth about $2,031 per pound, orders of magnitude ...
The only state in the country with a significant elver catch is Maine, where fishermen have voiced concerns in recent months about the possibility of a cut to the fishery's strict quota system.
Fishermen in the U.S.'s only commercial-scale fishing industry for valuable baby eels once again had a productive season searching for the tiny fish. Baby eels, called elvers, are often worth more ...
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.
Your aquarium should have a bed consisting of either sand or smooth rounded gravel. It should also have many large rocks with multiple openings and overhangs for shelter. The water flow should be set to a low level. Because this is a tropical species, the water should be maintained at a temperature range of 24–28 Celsius (75–82 Fahrenheit ...
