Sardinops
A genus of sardines found in warm oceans worldwide.
Sardinops is a group of small marine fish within the herring family. These species inhabit coastal waters across the Indo-Pacific, Atlantic and Pacific oceans. They grow up to 40 centimetres long and support major commercial fisheries, particularly in Australia where they feed tuna farms.

What it is
This genus belongs to the herring family and includes several species of small, silvery fish. Adults reach a maximum length of 40 centimetres. They are known by many local names such as blue pilchard or Pacific sardine, depending on the specific subspecies and region. The group was once thought to contain only one species but now includes three valid living types along with various subspecies.
Where it lives
These fish inhabit warm temperate and tropical waters across multiple ocean basins. Their distribution covers the Indo-Pacific region, the eastern Pacific coast, the southeastern Atlantic and the southwestern Indian Ocean. Specific populations include the Japanese pilchard, the Southern African pilchard and the Australian pilchard, each occupying distinct coastal zones within these broader areas.
How it lives
Information regarding specific dietary habits, schooling behaviour or natural predators is not detailed in the provided text. However, their abundance allows them to form large schools that can be targeted efficiently by commercial fishing vessels using wide nets.
Fish and people
In South Australia, this fish supports the largest single-species fishery by volume. Started in 1991, the industry uses purse seining to catch schools with large nets. Most of the harvest goes to southern bluefin tuna ranches near Port Lincoln as feed. A small portion is sold for human eating, bait or pet food. Quotas have risen from 1,000 metric tons initially to 38,000 metric tons by 2014.
Status and threats
The South Australian fishery is considered sustainable due to its fishing methods. Compliance issues arose in 2004 regarding quota evasion, such as unreported landings or dumping excess catch. Total catches peaked at nearly 57,000 metric tons in 2004-05 before stabilising around 32,000 metric tons annually.
