Read the passage and answer the questions:
Thanks to the blockbuster animated film Finding Nemo, clownfish are a perennial favourite among aquarium enthusiasts. Now a collaborative effort by the Maharashtra Mangrove Cell and Lucknow's National Bureau of Fish Genetic Resources (NBFGR) will help villagers in Maharashtra's mangrove belt make a living by cashing in on the fish's popularity. A team from the NBFGR is at Mumbai's Coastal and Marine Biodiversity Centre, nursing hundreds of eggs laid by seven pairs of clownfish. This clownfish hatchery, the first of its kind, will help the villagers set up a clownfish trade business. Marine aquarium trade is a booming business. The Mangrove Cell has helped them build storage tanks, in checking water quality, in understanding the behaviour of the fish, and in the tricks of aquarium trade.
Around 200 clownfish were brought from Tamil Nadu, Andaman Islands, and Lakshadweep. They were paired, and 57 pairs survived. The NBFGR team stated that the fish have laid several hundred eggs that hatch in a week. After the larva is born, it takes two weeks for metamorphosis, when they become miniature adults. The baby fish will be reared in the hatchery for 30 days, after which they will be handed over to the villagers for aquarium trade.
