Sodium chloride added to transport water and physiological responses of Matrinxã Brycon amazonicus (Teleost: Characidae)

Abstract: A adição de sal à água tem sido utilizada para a mitigação de estresse e aumento da taxa de sobrevivência em peixes. O presente estudo avaliou o efeito do cloreto de sódio (0,0; 1,0; 3,0 e 6.0 g/l) nas concentrações de cortisol plasmático, glicemia, triglicerídios, proteínas total plasmática, hematócrito, hemoglobina, número de eritrócitos, glicogênio e lipídio hepáticos, e lipídio muscular em matrinxã Brycon amazonicum adultos após quatro horas de transporte e durante período de recuperação de 96 h.

“…Total leukocyte counts for B. amazonicus juveniles obtained here (13,324 ± 7677 µL) were smaller than for young B. orbignyanus (23,290 ± 7041 µL) (Tavares- Dias and Moraes, 2006a), although has been used similar method for counting WBC, hence this indicates an interspecific variation. However, total leukocyte counts for B. amazonicus juveniles was higher than for juvenile B. amazonicus fed with a diet without complementary vitamin C (Abreu and Urbinati, 2006), because a different method of count was used. Matrinxã B. amazonicus differential leukocytes count has shown few variations in relative number when compared to some Bryconinae species from literature (Table 4).…”

“…TSP was used as a bioindicator of stress by salinity alteration in the plasma of hybrid striped bass (Morone chrysops × M. saxatilis; Riche 2007); for pollution stress, in the serum of catfish (Clarias lazera) (Adham et al 1999), carp (Cyprinus carpio) (Gopal et al 1997) and Nile tilapia (Oreochromis nicoticus) (ElGohary et al 2005); and for starvation stress in carp (Friedrich and Stepanowska 2001). TSP was also used to determine crowding stress in trout (Oncorhynchus mykiss) (Sutton et al 2000); ammonia stress in sea bass (Dicentrarchus labrax) (Coeurdacier and Dutto 1999); temperature stress in cod (Gadus morhua) (Magnadottir et al 1999); transport stress in dab (Limanda limanda) (Hutchinson and Manning 1996), matrinxã (Brycon amazonicu) (Carneiro and Urbinati 2002;Urbinati and Carneiro 2006) and trout (Oncorhynchus mykiss) (Jeney et al 1997); and stress following infection in carp (Cyprinus carpio) (Steinhagen et al 1997) and brown trout (Salmo trutta) (Ingram and Alexander 1977).…”

“…Em espécies nativas como o tambaqui (Colossoma macropomum), o pirarucu (Arapaima gigas), a matrinxã (Brycon amazonicus), o pacu (Piaractus mesopotamicus), o pintado (Pseudoplatystoma corruscans) e o jundiá (Rhamdia quelen) várias alterações hormonais, metabólicas, iônicas e hematológicas, em decorrência do estresse de transporte, foram registradas (GOMES et al, 2003;CARNEIRO, 2006;TAKAHASHI et al, 2006;FAGUNDES;URBINATI, 2008;CARNEIRO et al, 2009).…”

“…No experimento com b-glucano, os níveis de cortisol aumentaram significativamente imediatamente após o transporte para todos os tratamentos, refletindo a resposta primária descrita por Iwama et al (2004), sendo este resultado semelhante aos obtidos por Gomes et al (2003) com tambaquis e por Urbinati e Carneiro (2006) com matrinxãs, que apresentaram elevação do cortisol imediatamente após o transporte. Já em espécies como o pirarucu (Arapaima gigas), há grande latência nas respostas do cortisol, onde após o transporte este indicador permanece sem alteração e somente 24h após o transporte é que ocorre a elevação dos níveis de cortisol, o que é atribuído, em parte, ao seu estilo de vida (BRANDÃO et al, 2006;GOMES et al, 2006).…”
