Fish community, by-catch, biomass, specific richness, diversity Comunidad de peces, fauna de acompañamiento, biomasa, riqueza específica, diversidad Comunidade de peixes, fauna de acompanhamento, biomassa, riqueza específica, diversidade Discarded ichthyofauna associated to unregulated artisanal shrimp fishery in the Mar Muerto coastal lagoon, Gulf of Tehuantepec, Mexico, was characterized. Shrimp catches were sampled from October 2017 to January 2018 with fixed cod-end nets. In this study, discard averaged 64.2 ± 15.3% of the total biomass captured, while fish amounted to 51% to 79.5% of this discard, with an estimated general ichthyofauna/shrimp ratio of 1.89: 1 kg. No relationship was found between shrimp catch and discard ichthyofauna biomass. High values of diversity are recorded in November and December due to a greater presence of marine organisms. It was shown that cod-end net fishing potentially affects at least 73 fish species, which, according to their average size and species (9.9 ± 9 cm, standard length), may be juvenile and sub-adult individuals. The families best represented in the fish list were Carangidae, Ophichthidae, and Gerreidae. Although a relatively high richness is reported in the discard, only 4 species were dominant. Fifteen new records of fish were added to the known ichthyofauna in the local and regional context. Further characterizations on by-catch and discards are necessary to propose management actions and reduction of the fishing impact. Foi realizada, na lagoa costeira do Mar Morte Golfo de Tehuantepec no México, uma caracterização da ictiofauna descartada associada a uma pescaria artesanal desregulada de camarão. As capturas de camarão foram amostradas de outubro de 2017 a janeiro de 2018 com redes fixa tipo puçá. Neste estudo, o descarte integrou uma porcentagem média de 64,2 ± 15,3% da biomassa total capturada. Desse descarte, o grupo de peixes se integrou entre 51 e 79,5%, estimando uma proporção geral de ictiofauna/camarão de 1,89:1 kg. Nenhuma relação foi encontrada entre a captura de camarão e a biomassa da ictiofauna descartada. Altos valores de diversidade são apresentados nos meses de novembro e dezembro, devido à maior presença de indivíduos de afinidade marinha. Foi demonstrado que a pesca com puçá afeta potencialmente pelo menos 73 espécies de peixes, que, segundo o seu tamanho médio e espécie (9,9 ± 9 cm, comprimento padrão), podem corresponder a indivíduos juvenis e subadultos. As famílias melhoresrepresentadas na lista de peixes foram Carangidae, Ophichthidae e Gerreidae. Embora uma riqueza relativamente alta seja relatada no descarte, apenas 4 espécies foram dominantes. Destaca-se a inclusão de 15 novos registros de peixes à ictiofauna conhecida no contexto local e regional. É necessário realizar caracterizações adicionais sobre fauna de acompanhamento e descarte para propor ações de manejo e redução do impacto pesqueiro.
