“…Aquaculture initiatives must be incentivated, since they might considerably reduce collecting pressure over populations of targeted species (Calado et al 2003, Pomeroy et al 2006, Olivotto et al 2011, Murray & Watson 2014, specially because almost the totality of the native marine aquarium organisms exploited in Brazil are wild-caught and captive breeding of native marine ornamentals is restricted to a few species (e.g. Elacatinus figaro and Hippocampus reidi) (Meirelles 2008, Hora & Joyeux 2009, Ibama 2009, Côrtes & Tsuzuki 2010.…”

Abstract:Brazil has an important role in marine ornamental trade, exploiting native species for both international and domestic market. A few works have previously assessed wild species exploited by the Brazilian marine aquarium industry and most of them focused solely on fish. Hence, the present paper intends to address an information gap regarding the species currently traded in the country, as well as concerning their conservation statuses. Thus, different sources of information were investigated and each species was categorized in accordance with existing lists of threatened species. A wide variety of native species was identified in Brazilian marine aquarium trade, including not only fish but also invertebrates, seaweeds and macrophytes. Some of these species were legally protected, but are still commerced anyway. Such illegal exploitation of native species causes increasing concerns about the sustainability of the activity. Therefore, in order to reduce environmental impacts caused by marine ornamental trade, Brazilian authorities should encourage the implementation of eco-fees, the purchase of eco-labeled aquarium products, the development of sustainable ornamental aquaculture and ecosystem-based management initiatives. Keywords: Marine aquarium fish, marine invertebrates, seaweeds, marine macrophytes, illegal trade, threatened species. Espécies nativas explotadas pela aquariofilia marinha no BrasilResumo: O Brasil possui um papel importante no comércio de ornamentais marinhos, utilizando espécies tanto para exportação como para o mercado interno. Poucos trabalhos anteriores descreveram as espécies nativas utilizadas pela indústria brasileira de aquarismo marinho, e a maioria deles era focada exclusivamente no uso de peixes. Assim, o presente trabalho almeja preencher a falta de informação em relação às espécies atualmente exploradas no país, bem como relativas às suas categorias de conservação. Dessa forma, diferentes fontes de informação foram investigadas e cada espécie foi categorizada de acordo com as listas de espécies ameaçadas existentes. Uma grande variedade de espécies foi identificada no comércio do aquarismo marinho brasileiro, o que inclui não somente peixes, mas também invertebrados, macroalgas e macrófitas. Algumas dessas espécies não poderiam ser exploradas, mas mesmo assim seguem sendo comercializadas. Essa utilização ilegal de espécies nativas provoca preocupações frequentes acerca da sustentabilidade dessa atividade. Desse modo, para reduzir os impactos ambientais causados pelo aquarismo marinho, as autoridades brasileiras deveriam incentivar a implementação de taxas-ecológicas, a aquisição de produtos de aquário com selos ecológicos, o desenvolvimento sustentável da aquacultura ornamental e iniciativas de manejo baseadas no ecossistema. Palavras-chave: Peixes de aquário marinho, invertebrados marinhos, macroalgas marinhas, macrófitas marinhas, comércio ilegal, espécies ameaçadas.

“…In addition, the rearing organisms in closed systems is likely to lead to the production of hardier specimens that are far better in captivity and survive longer (Pomeroy et al, 2006;Olivotto et al, 2011). The aquaculture of ornamentals organisms can only be achieved through combination of science and technology in order to develop current techniques for ornamental aquaculture, in fact despite the exponential growth of marine ornamental market very few species are presently cultured (Olivotto et al, 2011).…”

The increasing demand for soft corals is reflected on the high attention of the scientific community during the last decades, with several studies focus on production techniques and optimization of coral husbandry. However, coral culture success is influenced by the interaction of different factors, such as water movement, temperature, nutrients, heterotrophic feeding and light conditions. Light plays a key role in the growth, reproduction and physiology of corals that host phototrophic symbionts and it has been found that the photoresponse of corals is species-specific. Several studies have already focused on the effects of irradiance on coral and its algal symbionts. Although, only a few works have investigated the role of the spectral quality of light on coral photobiology, physiology and growth. In the present study, we hypothesize that light spectrum can influence the growth performance of Leather Coral Sarcophyton spp.when exposed at identical intensities of photosynthetically active radiation (PAR). To test our hypothesis we evaluated the effect of contrasting light spectra with an identical PAR of 70 ± 10 μmol quantam −2 .s −1 emitted by T8 fluorescent lamps (used as a control treatment) and three different colours of Light Emitting Diode (LED), white, blue and red. It was evaluated survival and growth rates of Sarcophyton spp., an important soft coral in the marine aquarium trade and for the bioprospecting of marine natural compounds. Replicated coral fragments were obtained from two mother colonies and were exposed to the four types of light spectrum for a period of 30 days. At the end of the experiment period, the results showed 100% of survival in coral fragments, and specific growth rate (SGR) of 0,055 ± 0,09%/day in control group and 0,091 ± 0,019 %/day, 0,210 ± 0,031%/day and 0,380 ± 0,245%/day in, white, blue and red light, respectively. Moreover, in all treatments at end of experiment the zooxanthellae density was ±, ± and ± for white, blue and red light spectrum, respectively showing that all light promotes conditions for zooxanthellae growth. The results also showed a positive role of use a specific light spectrum in coral growth, namely blue and red spectrum. The use of light with specific light spectrum that increasing the growth and health of corals will minimizing the production costs, increasing the feasibility of ex situ production of ornamental corals and this study identify the best LED`s light spectrum for the growth of the leather coral Sarcophyton spp.

Aquaculture Perspective of Multi-Use Sites in the Open Ocean

Most studies on multi-use concepts of aquaculture and wind farms explored cultivation feasibility of extractive species, such as seaweed or bivalves. However, recent studies also included the cultivation of crustaceans or fish culture in the vicinity of wind turbines. Consequently, new approaches combine fed and extractive species in integrated multi-trophic aquaculture (IMTA) concepts for offshore multi-use to reduce nutrient output and the overall environmental impact of aquaculture operations. In this chapter the findings of a series of mussel and oyster cultivation experiments over several seasons are presented, which were conducted at different offshore test sites in the German Bight. Sites were selected within future offshore wind farm areas for an explicit multi-use perspective. Results have demonstrated successful growth and fitness parameters of these candidates and
