Sustainability

The contemporary commercial eel fishery dates from the mid-1960s when markets were established in Europe and Asia. Eel catches are greatly influenced by water temperature, flood events (increased catches) and drought conditions (reduced catches). Catches decline in winter months, particularly in the South Island. The eel fisheries in the South Island, Chatham Island and North Island were introduced to the Quota Management System from 2000-2004. Minimum and maximum size limits exist across the country. Recreational fishers are limited to a daily bag limit of six eels. They are also an important customary fishery, which is managed by authorisations issued under the fisheries regulations.  Indices of abundance for longfin and shortfin eels are available from commercial catch data for those areas that are commercially fished.Monitoring of recruitment is often combined with work to mitigate the effect of hydro-power dams.  

Nutrition

Eel (Shortfinned) is a good source

To quality for a 'good source' claim the food must contain at least 25% of the RDI.
The Recommended Dietary Intake (RDI) is considered to be the average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (97–98 per cent) healthy individuals in a particular life stage and gender group.

of Selenium

Selenium is necessary for normal immune system function and for the production of thyroid hormones and it contributes to the maintenance of hair and nails

, Vitamin A

Vitamin A is necessary for normal vision and the structure and function of skin and mucous membranes

, Niacin (vitamin B3)

Niacin (vitamin B3) is necessary for the release of energy from food and for the normal structure and function of skin and mucous membranes, and contributes to the reduction of tiredness and fatigue

, Vitamin B12

Vitamin B12 is necessary for normal neurological function and it contributes to blood formation, energy metabolism and to the growth and development in children

, Vitamin D

Vitamin D is necessary for normal bone structure and the utilisation of calcium and phosphorus and it contributes to the maintenance of normal teeth

and Vitamin E

Vitamin E is contributes to the protection of cells from free radical damage and to the normal growth and development of children

; and a source

To quality for a 'source' claim the food must contain at least 10% of the RDI.
The Recommended Dietary Intake (RDI) is considered to be the average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (97–98 per cent) healthy individuals in a particular life stage and gender group.

of Iodine

Iodine is necessary for the production of thyroid hormones, for normal neurological function and for normal energy metabolism, and it contributes to the growth and development in children

, Magnesium

Magnesium is necessary for normal nerve and muscle function and for teeth and bone structure and it contributes to normal energy metabolism

, Phosphorus

Phosphorus is necessary for normal teeth, bone and cell membrane structure and for energy metabolism

, Potassium

Potassium is necessary for water and electrolyte balance, it contributes to the functioning of the nervous system and normal muscle function; and to the normal growth and development of children

, Thiamin (vitamin B1)

Thiamin (vitamin B1) is necessary for the metabolism of carbohydrates and for normal neurological and cardiac function, and it contributes to the production of energy

, Riboflavin (vitamin B2)

Riboflavin (vitamin B2) is contributes to the transport and metabolism of iron, to the release of energy from food and to the maintenance of normal vision

and Vitamin B6

Vitamin B6 is necessary for the metabolism of protein and the transport and metabolism of iron and it contributes to immune system function, energy metabolism, to reduction of tiredness and fatigue, and to the regulation of hormonal activity

.

Seafood is a highly nutritious food and is a great source of protein

Protein is necessary for tissue building and repair, normal growth and development of bone in children and adolescents aged 4 years and over, and contributes to growth and maintenance of muscle mass

. Many species are low in saturated fat and a number of them are a good source of Omega 3

Omega 3 is a group of fatty acids that contribute to heart health

Tips

Eels are often smoked, and available as either fillets or pieces.
