The present study evaluated different concentrations of clove oil for anesthesia guppy (Poecilia reticulata). Adult female, male and juveniles fish were used to assess the influence anesthesia. animals individually submitted following concentrations: 50, 75, 100, 125 150 mg L-1. induction, recovery stages mortality 96 hours after experiment evaluated. All exposed experimental reached final stage female guppies respond differently induction by oil. Thus, it is recommended use on L-1 adult...
ABSTRACT Selenium (Se) is an antioxidant mineral and has been included in fish feed formulations the organic form of hydroxy-selenomethionine (OH-SeMet). This study evaluated how different concentrations this substance, supplemented diet, act on tambaqui (Colossoma macropomum) muscle before after a stressor (transportation). Juvenile fishes were divided into five treatments receiving 0.0; 0.3; 0.6; 0.9; 1.2 mg kg-1 Se supplementation for 75 days. After that period, exposed to transportation...
Para determinar as respostas de estresse do matrinxã após perseguição com puçá, juvenis (26,7±6,7 g) foram aclimatados em caixas plásticas e submetidos aos tratamentos: Controle (sem perseguição), Perseguição por 2 minutos, 5 10 minutos (quatro repetições, N=8/tratamento). Amostras sangue coletadas 15, 30 60 a para determinação cortisol, glicose, sódio, cloreto, potássio, hematócrito, hemoglobina, número total eritrócitos osmolaridade. O perfil das o exercício físico dos peixes não mostrou...
Heavy metals are highly toxic elements that present in the environment, especially water. Mercury chloride (HgCl2) stands out among these compounds because of its strong ability to induce damage any tissue with which it comes into contact. The gametes spawning aquatic animals, such as fish, susceptible damage. Thus, our objective was evaluate potential HgCl2 capacitation and activation Rhamdia quelen sperm. Semen collected from seven males activated 58 mM sodium (NaCl) containing 0...
This study proposes to investigate whether short restricted-feeding cycles during the pre-fattening phase of tambaqui (Colossoma macropomum) juveniles affect their production performance and yield in a semi intensive system if this practice can be introduced as an alternative reduce costs species. The fish (8.07 ± 0.07 g) were subjected periods under controlled laboratory conditions (experimental boxes) for 60 days (Phase I). Three feeding strategies tested, namely: dairy (Control); five...
Abstract This work evaluated the effect of triiodothyronine ( T 3 ) on larviculture matrinxã, Brycon amazonicus . Oocytes three females were pooled, fertilized with pooled semen two males and separated in four batches that immersed solutions as follows: M 1 (control – water); 2 (0.01 mg/L ); (0.05 4 (0.1 ). Triiodothyronine did not affect fertilization rate number hatched larvae. Weight larvae was significantly higher treatments M3 M4 , well among sampled at Day 12 all treatments. After d...
ABSTRACT Tambaqui, Colossoma macropomum, is one of the most produced species in Brazilian fish farming, which has boosted development new technologies to increase its productivity. The aim this study was evaluate production performance two second-generation tambaqui stocks selectively bred for weight gain a semi-intensive rearing system and assess influence on total cost. We analyzed 300 (initial mean standard length 160 g 17 cm, respectively) families (A B, 150 each). were individually...
This study evaluated stress indicators of juvenile piau (Leporinus friderici) during and after a 4-hour transportation in order to establish an appropriate protocol for this type fish. Fish were transported plastic bags (133.1 g/L) sampled before loading, 1, 2, 3 4 h (2, 6, 12 24 h). Blood samples analyzed cortisol glucose levels, hematocrit, hemoglobin level, number mean corpuscular volume erythrocytes. Water pH, dissolved oxygen, temperature ammonia monitored before, transportation. No...
Piava (Leporinus obtusidens) is one of the main cultivated native fish and most caught in Rio Grande do Sul, Southern Brazil. The objective this work was to compare carcass fillet yields piava, females males, collected from wild (Treatment 1 - T1) culture 2 T2) analyze chemical composition fillets. For purpose, four males each treatment were used. T1 presented significant higher values (P<0.05) yield. Chemical analyses indicated that originating farming, independent sex, showed for...
Foram avaliadas as respostas fisiológicas de estresse tambaqui e híbrido tambatinga quando submetidos a práticas rotineiras em sistema criação, como realização periódica biometrias. Por 270 dias cultivo, os peixes foram biometrias mensais e, ao final do período, o sangue foi colhido seis tempos amostragem (antes; imediatamente após; 2, 24, 48 72 h após biometria) para avaliação indicadores fisiológicos estresse. Tambatinga é mais susceptível estresse, pois apresentou maiores níveis...
The objective of this study was to evaluate different menthol concentrations for the anesthesia adult females, males, and juvenile guppy (Poecilia reticulata). To end, 30 females (0.379 ± 0.108 g), males (0.220 0.049 juveniles (0.033 0.016 g) were used. animals individually exposed five (50, 100, 150, 200, 250 mg L-1), six fish per concentration. induction times, anesthetic recovery, mortality up 96 h after experiment evaluated. concentration 50 L-1 did not induce in any studied groups. 100...
The present study aimed to evaluate the physiological responses transport stress in juvenile tambaqui (Colossoma macropomum) fed a diet supplemented with hydroxy-selenomethionine (OH-SeMet; Selisseo®, Adisseo) and determine through biomarkers whether selenium supplementation could reduce impact of on resilience. Juvenile fish (15.71 ± 1.90 g) were randomly distributed into five experimental groups; one basal without inclusion OH-SeMet (0.0 mg Se/kg) four other groups diets form at...
A composição proteica dos peixes é baseada em alto teor de proteínas miofibrilares, sendo estas responsáveis pela formação géis e emulsões.Um ingrediente rico destas características o surimi.Este trata-se uma pasta pescado oriunda carne peixe moída ou separada mecanicamente (CMS), devidamente lavada água potável fria, para remoção sujidades como gordura pigmentos.Em seguida, adiciona-se agentes crioprotetores (ACPs) contribuição na gel.Porém, isto pode influenciar diretamente cor do...
