Atlantic goliath grouper, itajara, bodete, badejão or whiting white. Many are the names used to identify Epinephelus itajara, which in local language means "Lord of the stones." The species was first described in 1822 by the German naturalist researcher Martin Heinrich Carl Lichtenstein, providing a brilliant analogy to one of the main habitats used by one of the greatest groupers representatives (Family Epinephelidae) in the Atlantic Ocean.

Out of curiosity, Brazilian grouper differs from the Portuguese one, indeed! In Portugal the species is Epinephelus marginatus, the dusky grouper, known as the “real” grouper in Brazil. Today, the Brazilian grouper has a somewhat sad path designed to survival against human action, but that has been gradually changing with some signs of improvement.

Giant King Lonely and docile, the Atlantic goliath grouper has a wide geographical distribution [Atlantic, from North Carolina (USA) - Caribbean - to Santa Catarina in southern Brazil, and the African coast from Senegal to Congo], inhabits a wide diversity of environments, including both rocky shores of subtropical waters to tropical reefs, estuaries and mangroves. In fact, it is in mangroves that they spend much of their early lives, finding shelter and plenty of food. Known for their large size, they may reach 2.5 meters in length, weigh 450 kg and live for around 40 years. They are carnivorous that feed on crustaceans (lobsters), fish (catfish and rays), and even young turtles.

nursery habitats near coast. The set of biological characteristics that involve their slow but significant growth and their aggregations for reproductive purposes, although making them extremely vulnerable to capture, also provide a unique spectacle when we dive with them.

Not always the diving with these fishes was merely considered a contemplative experience. Historically, they have been captured as magnificent and valuable trophies. Reports and stories of amazing fish that demanded colossal efforts to

be captured, and then brought to light are well known and were often repeated along the Brazilian coast.

But the days when these groupers were displayed as large fishery awards are in the past. Over the last decades the Atlantic goliath grouper population in Brazil was dramatically reduced by both sport and commercial fishing. Considered critically endangered by the International Union for Conservation of Nature (IUCN) since 2002, the Atlantic goliath grouper is a protected species in Brazil, but still at risk because the moratorium extends only until 2015!

One of the highlighted initiatives is the photo-identification project which aims to obtain information from labelling/recapture techniques with the creation of an images database on behaviour and colour and movement patterns. Despite scarce in natural environments, this species is incredibly attracted to structures such as shipwrecks, artificial reefs and piers. The initiative main idea is to raise awareness in society that the Atlantic goliath grouper is more valuable alive than dead, manly its great contemplative diving potential.

In addition, important aquaculture field research began in 2012. Research on their reproduction is unprecedented in the world. According to Dr. Eduardo Gomes Sanches, Project Serranids coordinator: "Currently the Fisheries Institute in São Paulo is the only institution in Brazil maintaining a serranids semen bank, contributing for this important species preservation to future generations.�

"The efforts include their captivity maintenance, fish genetic variability evaluation studies, a sperm bank and juveniles ambitiously obtained and produced in captivity, as has already been done with the dusky grouper" declares MSc.
