| Like anchovies and herrings, they are small, primitive fish belonging to the group known as clupeoids. |
| Herring, unlike most other clupeoids, are total spawners with a group-synchronous ovarian organization. |
| It may, therefore, be useful to briefly review some of the general characteristics of clupeoids to indicate what we might expect to find in Lake Tanganyika. |
| This is an important spawning and nursery ground for many important pelagic fishes such as clupeoids, horse mackerel, scomber and saury. |
