Description Myctophids are mesopelagic fishes belonging to family Myctophidae commonly called as 'Lanternfishes', Ecologically, myctophids link primary consumers like copepods, euphausiids and top predators like squids, whales and penguins in a typical food web. Lantern fishes become a major part of deep scattering layers (DSL) during migration along with other fauna such as euphausiids, medusae, fish juveniles, etc. They are important contributors of organic carbon in the form of their remnants and fast sinking faeces, which get deposited on ocean beds. Economically, they are a good source of protein, lipids and minerals, which is used as fishmeal for poultry and animal feed and as crop fertilizers. Few species are considered edible, but proper processing difficulties on a higher scale limit myctophids as human food. Myctophids have a life span of approx. 1?5 years and low fecundity rates (100?2,000 eggs per spawn). This trait is a disadvantage, if continuous utilization of their population, for e.g., for fish meal industries etc., occurs without giving them a chance to revive and recover. This compilation of information and ideas from various sources of myctophid research around the world, particularly from the Indian Ocean is to understand their ecological and economic importance. It also puts forth new ideas to bring about conservation and restoration of this vulnerable resource.
