Mass death may be due to a ‘stress event’ linked to climate change, officials say ... Juvenile eels, known as elvers, ... Elvers thrive when water temperatures range between 16 and 18C along ...
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).
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.
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 New Zealand longfin eel (Anguilla dieffenbachii) is a species of freshwater eel that is endemic to New Zealand. It is the largest freshwater eel in New Zealand and the only endemic species – the other eels found in New Zealand are the native shortfin eel (Anguilla australis), also found in Australia, and the naturally introduced Australian longfin eel (Anguilla reinhardtii).
The Atlantic States Marine Fisheries Commission decided Wednesday that U.S. fishermen will be allowed to harvest a little less than 10,000 pounds (4,536 kilograms) of the eels
Anguillids can withstand a wide variety of temperatures but the optimum temperature in cultured species is between 22 °C and 28 °C- at this temperature growth is maximised [8] Recent work has determined that the optimal water temperature is for maximal growth of short-finned eels is 26.5 °C, and salinity is optimum at 17.5%.
