“…Thus, acclimation is a set of adaptations under laboratory conditions, and it is important to ensure the conditions and animal quality for performing reliable laboratory experiments (Brasil, 1988;Resgalla Junior et al, 2008;Maroñas and Damborenea, 2009). The acclimation time to L. fortunei, as reported in the literature, ranges from 0 to 20 days (Maroñas and Damborenea, 2009;Oliveira et al, 2010b;Di Fiori et al, 2012;Calazans et al, 2013;Montresor et al, 2013). In fact, in some experiments, the acclimation time is not reported (e.g., Montalto and Drago, 2003;Pestana et al, 2009;Oliveira et al, 2010a).…”

“…A literature review identifies a lack of standardization in the procedures that are used in experimental studies of L. fortunei, such as sampling, transport, rearing, monitoring of the animal's health, acclimation time to the laboratory, size range of the tested animals, monitored physico-chemical parameters, food availability during the experiments, and criteria for the selection of suitable specimens to be tested for each bioassay (Cataldo et al, 2003;Pereyra et al, 2011Pereyra et al, , 2012Di Fiori et al, 2012;Mansur et al, 2012;Calazans et al, 2013;Montresor et al, 2013;Sylvester et al, 2013). In fact, differences between the tested procedures in experimental studies may account for some of the discrepancy observed in the literature results (Rolla and Mota, 2010;Montresor et al, 2013).…”

Physiological response of invasive mussel Limnoperna fortunei (Dunker, 1857) (Bivalvia: Mytilidae) submitted to transport and experimental conditions

Successful animal rearing under laboratory conditions for commercial processes or laboratory experiments is a complex chain that includes several stressors (e.g., sampling and transport) and incurs, as a consequence, the reduction of natural animal conditions, economic losses and inconsistent and unreliable biological results. Since the invasion of the bivalve Limnoperna fortunei (Dunker, 1857) in South America, several studies have been performed to help control and manage this fouling pest in industrial plants that use raw water. Relatively little attention has been given to the laboratory rearing procedure of L. fortunei, its condition when exposed to a stressor or its acclimation into laboratory conditions. Considering this issue, the aims of this study are to (i) investigate L. fortunei physiological responses when submitted to the depuration process and subsequent air transport (without water/dry condition) at two temperatures, based on glycogen concentrations, and (ii) monitor the glycogen concentrations in different groups when maintained for 28 days under laboratory conditions. Based on the obtained results, depuration did not affect either of the groups when they were submitted to approximately eight hours of transport. The variation in glycogen concentration among the specimens that were obtained from the field under depurated and non-depurated conditions was significant only in the first week of laboratory growth for the non-depurated group and in the second week for the depurated group. In addition, the tested temperature did not affect either of the groups that were submitted to transport. The glycogen concentrations were similar to those of the specimens that were obtained from the field in third week, which suggests that the specimens acclimated to laboratory conditions during this period of time. Thus, the results indicate that the air transport and acclimation time can be successfully incorporated into experimental studies of L. fortunei. Finally, the tolerance of L. fortunei specimens to the stressor tested herein can help us understand the invasive capacity of this mussel during the establishment process.Keywords: bioinvasion, glycogen, golden mussel, physiology.Resposta fisiológica do mexilhão invasor Limnoperna fortunei (Dunker, 1857) (Bilvalvia: Mytilidae) submetido ao transporte e condições experimentais ResumoA criação bem sucedida de animais em condições de laboratório para processos comerciais ou experimentais é uma cadeia complexa que inclui vários fatores de estresse (ex. coleta e transporte) que tem como consequência a redução das condições naturais do animal, prejuízos econômicos e resultados biológicos inconsistentes.

“…De acordo com Darrigran (2002) este molusco pode ser encontrado em outras usinas e reservatórios pertencentes a bacia do Rio Paraná, responsável por causar diversos prejuízos de ordem econômica e ecológica e segundo Calazans et al (2013), o mexilhão já se propagou até a fronteira norte do Pantanal e apresenta riscos de chegar até o Rio Amazonas e representa séria ameaça para a biodiversidade aquática dos rios.…”

“…O controle das populações do mexilhão dourado e sua eliminação dos rios é considerado impossível (CALAZANS et al, 2013), e segundo DARRIGRAN e DAMBORENEA (2006), o que se busca no caso é apenas o controle da invasão da espécie afim de diminuir o impacto ambiental, pois este invasor já se estabeleceu na América do Sul. O mexilhão dourado é responsável pela causa de graves impactos sobre o ambiente, provocando alterações na biodiversidade nativa, desestruturação do ecossistema, causando perdas naturais e econômicas nas regiões infestadas (DARRIGRAN et al, 2012).…”

ResumoA avicultura brasileira ocupa posição de destaque no cenário mundial e existe a necessidade de que esta produção ocorra de forma sustentável, sendo assim a nutrição destes animais deve ser realizada de forma que provoque o menor impacto ambiental possível. Frente ao exposto surgem as conchas calcárias do mexilhão dourado que é um molusco invasor que ocupa grande parte dos rios de água doce da América do Sul e é responsável por gerar grandes impactos ambientais. O alto teor de cálcio (Ca) presente no mexilhão dourado faz com que este seja um potencial alimento com capacidade de substituir o calcário calcítico em dietas de frangos de corte, porém o seu hábito alimentar filtrador faz com que este possa conter teores de metais tóxicos como o cádmio (Cd) e o chumbo (Pb) que se contidos no interior do mexilhão podem causar contaminação dos frangos e conseqüentemente também dos produtos alimentícios derivados destes. Palavras chave:Limnoperna fortunei; cálcio; contaminantes; metais pesados tóxicos. AbstractBrazilian poultry farming occupies a prominent position in the world scenario and there is a need for this production to occur in a sustainable way, so the nutrition of these animals must be carried out in a way that causes the least possible environmental impact. In front of it, the calcareous shells of the golden mussel, an invading mollusk that occupies a large part of the freshwater rivers of South America, arise and are responsible for generating large environmental impacts. The high content of calcium present in the golden mussel makes it a potential food with the capacity to replace calcitic limestone in broiler diets, but its feeding habit makes it possible to contain contents of toxic metals such as cadmium (Cd) and lead (Pb) that are contained inside the mussel can cause contamination of the chickens and consequently of the food products derived from them.

“…Pacheco and Rebelo [13] proposed a procedure in R software [14] for the determination of lethal concentrations, using a dataset from Calazans et al [15] on NaCl toxicity to mollusks. The authors did not include the Abbott correction due to absence of mortality in the control treatment.…”

Several thousands of chemical substances are registered every year for different purposes, and sometimes many of them are claimed to play the same role. To establish and compare their toxicities, the determination of the lethal concentrations is usually necessary and should account for natural mortality. However, many of the statistical software packages used for that purpose do not readily integrate control mortality or adjust the best link function to the data during the process. This manuscript proposes an "lc" function in the R open source that aims at the effective determination of lethal concentrations. Furthermore, it performs the procedure with the appropriate link function. The "lc" application on the example provided revealed that the complementary log link function is adequate.
