Location
They are found around the coast in the sandbanks and mudbanks of sheltered bays from the low tide mark out to about 50 metres depth. They lie on the seabed with the flat shell uppermost, often singly but sometimes grouped in beds.
Attributes
Fan-shaped bivalve shell with deep ridges that radiate from the hinge. Colours are variable, including brown, orange, yellow, pink, or flesh-coloured or a mix of these. The upper valve of the shell is flat, and the lower valve is concave. The flesh is white and the roe is usually bright orange. They move by suddenly closing the shell to shoot water from the hinge. This propels the shellfish in a series of jerky jumps. Scallops have two rows of eyes around the mantle, which can sense danger when the valves of the shell are open.
Family
Scallops belong to the Pectinidae family (scallops).
Spawning
Spawning occurs in the spring and early summer. They mature rapidly, often reaching the legal size of 10 centimetres within three years.
Sustainability
One of our most popular shellfish, scallop harvesting is subject to controls on the season and hours of fishing in addition to the catch limits set under the Quota Management System. Minimum sizes are set for both recreational and commercial fisheries. Commercial harvesting is only permitted in areas where biotoxin testing has been completed. Monitoring of shellfish and water quality is carried out to specifications set by the Ministry for Primary Industries and international markets. A temporary closure for commercial and recreational scallop harvesting in the Nelson and Marlborough Sounds area for the 2016-17 season was announced by the Ministry in July 2016 to enable stocks to rebuild.
Fishing methods
The main dredging areas are Tasman Bay and Golden Bay, Marlborough Sounds, Coromandel coasts, and Northland coasts. They are best harvested before they spawn.
Nutrition
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.
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
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 B12 is necessary for normal neurological function and it contributes to blood formation, energy metabolism and to the growth and development in children

Phosphorus is necessary for normal teeth, bone and cell membrane structure and for energy metabolism
Magnesium is necessary for normal nerve and muscle function and for teeth and bone structure and it contributes to normal energy metabolism
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
Zinc is necessary for normal immune system function, contributes to normal skin structure and the healing of wounds, the maintenance of bones, hair and nails
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
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
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
Omega 3 is a group of fatty acids that contribute to heart health
Tips
Scallops are tender and juicy when cooked quickly on a high heat with a light, gentle touch. If overcooked, their texture can become rubbery.
They should be removed from heat as soon as the flesh changes from translucent to white.
Grilled/ seared scallops are very popular, however they can also be sautéd, baked, barbequed, fried, poached, added to a paella, pasta or risotto or marinated.
Buying & Storage Tips
Scallops should be bought plump and fresh, with firm lustrous flesh, showing no signs of discolouration or dryness. Scent is also a good indicator of freshness - scallops should smell slightly sweet and pleasantly briny but not sharp.
