“…These similarities indicate that the newly reported specimen most likely originated from the Red Sea; hence it invaded the Mediterranean via the major common vector, the Suez Canal. Another possible route for introducing G. reticularis into the Mediterranean is based on the genus Gymnothorax providing many species for the world's ornamental fish trade (Monteiro-Neto et al 2003;Jayalal & Ramachandran 2012). It is therefore also possible that the reported specimen of G. reticularis was simply released by aquarists into the Levant Basin.…”

“…In the Brazilian aquarium trade, these two families are among the most representative in species richness (Gasparini et al 2005). In the state of Ceará (one of the main centres of the Brazilian ornamental fish trade), H. ciliaris, P. paru, Hippocampus erectus, Pomacanthus arcuatus and Holacanthus tricolor made up 50% of the total trade between 1995 and 2000 (Monteiro Neto et al 2003). Among the species evaluated, H. ciliaris is the most harvested by the Brazilian aquarium trade (IBAMA -Federal Act 56/04).…”

“…The import value worldwide of marine fish and invertebrates is estimated to be between US$24 and 40 million annually (Wood 2001a). Nearly 120 species are currently harvested in the Brazilian aquarium trade (Monteiro Neto et al 2003). Most belong to the family Pomacanthidae (Araújo and Albuquerque Filho 2005) and species of the Chaetodontidae are among the most exported (Monteiro Neto et al 2003;Nottingham et al 2000).…”

Although other fisheries that use traps have an effect on ornamental marine fish stocks (through bycatch), these stocks have only been managed through a Federal Act (56/04) established in 2004 by the Brazilian environmental protection agency (Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis -IBAMA), which monitors the ornamental fish trade through export quotas.…”

The ornamental fish trade has considerable potential for damaging reef environments. Nearly 120 species are currently harvested in the Brazilian trade and little attention has been paid to the effects of the accidental catch of these species. Records of ornamental fish by-catch and the susceptibility and resilience of species from the major Brazilian families in the aquarium trade were examined to test a method and determine the sustainability of these catches. Each species was assessed based on two groups of criteria: (1) relative vulnerability to capture; and (2) population resilience to mortality due to fishing efforts. Each species was also ranked (1-3) for criteria regarding ecology, biology, catchability, numbers of individuals exported by aquarium companies and mortality index. These criteria were then weighted and each species rank in the two groups of criteria was plotted. Nineteen species from 10 families were recorded. The species least likely to have sustainable catch rates included Holacanthus tricolor, H. ciliaris, Chaetodon striatus and Pomacanthus paru. This approach is a useful alternative for management efforts and the assessment of catch sustainability in newly developed multi-species fisheries with limited available data, which occur in areas of high species richness such as reefs.

“…Individuals have a vibrant purple and yellow colouration, and have become increasingly exploited by the ornamental trade (Monteiro-Neto et al, 2003;Gasparini et al, 2005). This, combined with loss of habitat due to degradation of coastal waters, has led the species to be classified as endangered (Brasil, 2004;Sampaio and Notthingham, 2007).…”

Rediscovering hermaphroditism in Grammatidae with the description of the testicular gland in Brazilian Basslet Gramma brasiliensis

et al. 2016

Many aspects of sex change in reef fishes have been studied, including behavior and social organization. However, gonad histology remains the most robust way to identify sexual patterns in fishes. Some uncommon tissues remain poorly described, such as the accessory gonadal structures found in species from the Gobiidae family, which are rare in other bony fishes. This is the first report of the testicular gland in Gramma brasiliensis and for the Grammatidae family. Between April 2011 and February 2012 eighty specimens were collected during four dive campaigns on the Taipus de Fora reef (13°56'20"S 38°55'32"W), Bahia, Northeast Brazil, and their sex was determined. Thirteen per cent of the active-females and 90% of the active-males had testicular gland tissue in their ovotestis. This discovery led to additional research into the characteristics of the gland tissue and its relationship with gonadal maturation. Three patterns of testicular gland development were found in Brazilian basslet ovotestis. Both ova and sperm-producing gonad contained testicular gland tissue, and the appearance of this tissue seems to be the first modification of ovotestis tissue marking the beginning of the protogynous sex-change process in G. brasiliensis.Keywords: accessory gonoduct structure, sex change, hermaphroditism, reef fish. Redescobrindo o hermafroditismo em Grammatidae com a descrição da glândula testicular de Gramma brasiliensis ResumoDiversos aspectos da troca de sexo em peixes recifais vem sendo estudados, incluindo comportamentos e organização social. Entretanto, a histologia das gônadas continua sendo a maneira mais robusta para se identificar padrões sexuais em peixes. Alguns tecidos incomuns, tais como as estruturas anexas a gônada encontradas em espécies da família Gobiidae e raras em outras espécies são pouco estudados. Este trabalho é a primeira descrição da glândula testicular em Gramma brasiliensis e para a família Grammatidae. Entre abril de 2011 e fevereiro de 2012, oitenta espécimes foram coletados durante quatro amostragens no recife de Taipus de Fora (13°56'20"S 38°55'32"W), Bahia, Brasil, e tiveram seus sexos determinados. Treze por cento das fêmeas ativas e noventa por cento dos machos ativos apresentaram tecido da glândula testicular em suas gônadas. Esta descoberta levou ao estudo da características dessa estrutura e sua relação com a maturação gonadal. Foram identificados três padrões de desenvolvimento da glândula testicular nas gônadas do Gramma brasiliensis. Tanto as gônadas produtoras de espermatozoides quanto as de oócitos apresentaram tecido da glândula testicular, e o surgimento desse tecido parece ser a primeira modificação gonadal do início da troca de sexo protogínica em G. brasiliensis.Palavras-chave: estrutura anexa ao gonoduto, troca de sexo, hermafroditismo, peixe recifal.
