Based on light and scanning electron microscopical studies, two new and one specifically not identified gonad-infecting species of Philometra Costa, 1845 (Nematoda: Philometridae) are described from the ovary of marine fishes of the genus Epinephelus Bloch (Serranidae, Perciformes) in the Bay of Bengal, off the eastern coast of India: P. indica sp. nov. (male and females) from the honeycomb grouper E. merra Bloch, P. tropica sp. nov. (males and females) from the duskytail grouper E. bleekeri (Vaillant) and Philometra sp. (only females) from the cloudy grouper E. erythrurus (Valenciennes). Philometra indica is mainly characterized by the length of spicules 192–195 μm and the gubernaculum 84 μm, the distal tip of the gubernaculum without a dorsal protuberance, and by the presence of five pairs of caudal papillae. Philometra tropica is mainly characterized by the spicules conspicuously ventrally distended at their posterior halves, the distal tip of the gubernaculum with a dorsal protuberance, and the presence of three pairs of caudal papillae.

On 5 March 2006 an adult specimen of white grouper, Epinephelus aeneus (Geoffroy Saint-Hilaire, 1817), was caught with long-line gear off the Island Dugi otok (between islets Mužanj and Sakarun, eastern Adriatic Sea, Croatian coast, 44°06′46.9″N; 14°53′47.08″E) on a soft, sandy bottom at a depth of 40 meters. The capture location is around 400 km north of the northern range of distribution in the Adriatic and around 800 km north of the northern limit of distribution published earlier. This is the northernmost occurrence of the white grouper in the Mediterranean area. As a top carnivorous species and among the largest coastal fish species, groupers could probably influence ecology of many native fish species and affect local artisanal fishery.
