Features
Sardines are small, oily fish that belong to the herring family. They have a streamlined body shape that is ideal for fast swimming, with a pointed head and a forked tail. Sardines typically grow to be between 15 and 20 centimeters (6-8 inches) in length and weigh around 100 grams (3.5 ounces).
Their coloration is typically silvery-blue on the back and sides, fading to a lighter silver on the belly. Sardines have a series of small scales along their lateral line, which helps them detect vibrations in the water and avoid predators.
The fins of sardines are important for their swimming and maneuverability. They have two dorsal fins, located on their back, that work in tandem to stabilize their swimming and help them make quick turns. Sardines also have an anal fin and a pair of pectoral fins, which are located on the sides of their body and help them to steer and brake.
Sardines are known for their impressive swimming speed, which can reach up to 60 kilometers per hour (37 miles per hour) in short bursts. They often swim in large schools, using their speed and agility to evade predators like dolphins and sharks.
Habitat and Food
Sardines are a schooling fish and prefer to live in large groups. They can be found in both shallow and deep waters, but tend to stay near the surface of the water column. Sardines are often found near the coast, but can also be found offshore in deeper waters. In general, they tend to swim at depths between 25 and 100 meters.
Sardines are often found near the shore, particularly in areas with rocky coastlines or reefs. However, they can also be found further offshore in open waters.
Sardines are opportunistic feeders and will eat a variety of small organisms, including plankton, small crustaceans, and fish larvae. They are also known to eat squid and small fish. Sardines are filter feeders, using their gills to strain plankton from the water as they swim.
IUCN Status
According to the International Union for Conservation of Nature (IUCN), the conservation status of Sardinella longiceps is currently listed as “Least Concern”. This means that the species is not considered to be at significant risk of extinction in the near future.
However, it is important to note that overfishing and habitat destruction can still pose a threat to the long-term survival of this species, as well as other marine species in the region. Therefore, efforts to sustainably manage and conserve the Indian oil sardine population and its habitat should continue to be a priority.
