Relevance to Humans and Ecosystems
S. madarensis is a distinctly elongate Sardinella while also having a variably protruding belly. These fish have a median number of gill rakers and their upper pectoral fin rays are white on the outer side with a black membrane in between. They are very hard to distinguish from Sardinella aurita except that these fish have only 7 rays on their pelvic fins and no black spot on the hind part of their gill cover. They also have a gray caudal fin (see Fish anatomy) with black tips.
S. madarensis catches have decreased from 1.8 tonnes per trip in 2003 down to 1.5 tonnes in the following two years. The major fishing grounds for these fish are off the coasts of Senegal and Morocco. Over the course of the last ten years the average size of these fish has decreased down from 35 cm to 32 cm. Experts say that these changes are in large part due to very active Dutch commercial fishing in the region. The
These Sardinella can handle very low salinities when they travel into estuaries and lagoons and spend most of their lives near the surface of the water. They feed on phytoplankton and fish larvae. These are some of the larger fish in the genus and grow to as much as 35 cm.
