Genetic diversity of invasive and native Cichla (Pisces: Perciformes) populations in Brazil with evidence of interspecific hybridization
Journal of Fish Biology - Tập 69 Số sb - Trang 260-277 - 2006
Alessandra Valéria de Oliveira, Alberto José Prioli, Sônia Maria Alves Pinto Prioli, Thaís Souto Bignotto, Horácio Ferreira Júlio, Helaine Carrer, Carlos Sérgio Agostinho, Laudenir M. Prioli
Invasive and native populations of the Amazonian fishes ‘peacock bass’Cichla monoculus and of a not yet described species ‘blue tucunaré’ here referred as Cichla sp. ‘Azul’ were analysed for genetic diversity using the hypervariable domain of the mitochondrial DNA (mtDNA) control region plus steady diagnostic random amplified polymorphi...... hiện toàn bộ

Current issues in fish welfare
Journal of Fish Biology - Tập 68 Số 2 - Trang 332-372 - 2006
Felicity A. Huntingford, Colin E. Adams, Victoria A. Braithwaite, Sunil Kadri, T.G. Pottinger, Peter Sandøe, James Turnbull
Human beings may affect the welfare of fish through fisheries, aquaculture and a number of other activities. There is no agreement on just how to weigh the concern for welfare of fish against the human interests involved, but ethical frameworks exist that suggest how this might be approached.Different definitions of animal welfare focus on an animal's condition, on its sub...... hiện toàn bộ
Identification and expression of the laboratory of genetics and physiology 2 gene in common carp Cyprinus carpio
Journal of Fish Biology - Tập 86 Số 1 - Trang 74-91 - 2015
Xianglin Cao, J. J. Chen, Yongbing Cao, Guoxing Nie, Quanyuan Wan, L. F. Wang, Jianguo Su
In this study, a laboratory of genetics and physiology 2 gene (lgp2) from common carp Cyprinus carpio was isolated and characterized. The full‐length complementary (c)DNA of lgp2 was 3061 bp and encoded a polypeptide of 680 amino acids, with an estimated molecular mass of 77 341·2 Da and a predicted isoelectri...... hiện toàn bộ
Phylogenetic relationships among the mollies (Poeciliidae: Poecilia: Mollienesia group) based on mitochondrial DNA sequences
Journal of Fish Biology - Tập 53 Số sA - Trang 64-81 - 1998
Margaret B. Ptacek, Felix Breden
A 505‐bp sequence from the control region (D‐loop) and the complete 1047 bp of the NADH dehydrogenase subunit 2 (ND2) gene were examined for individuals from 11 species of mollies included in the group Mollienesia. All three species of sailfin mollies of the Poecilia latipinna species complex were included (P. latipinna, P....... hiện toàn bộ
Cold shocks: a stressor for common carp
Journal of Fish Biology - Tập 57 Số 4 - Trang 881-894 - 2000
Michael W.T. Tanck, G.H.R. Booms, E.H. Eding, S. E. Wendellar Bonga, J. Komen
The stress response of common carp Cyprinus carpio was studied by evaluating plasma cortisol, glucose and lactate after single or multiple rapid temperature drops (ΔT: 7, 9 or 11° C). All three amplitudes used induced a significant rise in plasma cortisol levels. Peaks occurred within 20 min after onset of the cold shock. No stress‐related secondary metabolic changes were observed in any o...... hiện toàn bộ
Seasonal changes in the hypo‐osmoregulatory ability of brook charr: the role of environmental factors
Journal of Fish Biology - Tập 56 Số 2 - Trang 347-373 - 2000
Guy Claireaux, Céline Audet
In winter, brook charr Salvelinus fontinalis demonstrated poor osmoregulatory ability. Saltwater (SW) transfer resulted in sharp increases in plasma osmolality and chloride levels, a decrease in white muscle water content and high mortality. A clear improvement of the hypo‐osmoregulatory mechanism e.ciency was observed in spring; by May or June, fish achieved ful...... hiện toàn bộ
Plasma ionic regulation and gill Na+/K+‐ATPase changes during rapid transfer to sea water of yearling rainbow trout, Salmo gairdneri: time course and seasonal variation
Journal of Fish Biology - Tập 34 Số 6 - Trang 829-840 - 1989
Steffen S. Madsen, E. T. Naamansen
Danish rainbow trout, Salmo gairdneri Richardson, (40–65 g) were transferred to 28%o sea water at intervals throughout the early spring and summer. Gill Na+/K+‐ATPase of fish kept in fresh water surged distinctly during May. Simultaneously, a body silvering occurred and plasma concentrations of Cl−, N...... hiện toàn bộ
Cortisol and glucose responses after acute stress by net handling in the sparid red porgy previously subjected to crowding stress
Journal of Fish Biology - Tập 51 Số 1 - Trang 21-28 - 1997
Josep Rotllant, Lluís Tort
In red porgy Pagrus pagrus subjected to 3 weeks of chronic stress by crowding, plasma cortisol remained significantly higher in crowded fish compared to controls. There was no significant effect of crowding on plasma glucose levels. When the crowded fish were subjected to an acute handling the plasma cortisol response was similar to that of the uncrowded fish. No...... hiện toàn bộ
Development of a microtitre plate indirect ELISA for measuring cortisol in teleosts, and evaluation of stress responses in rainbow trout and gilthead sea bream
Journal of Fish Biology - Tập 68 Số 1 - Trang 251-263 - 2006
Adrián Tintos‐Gómez, Jesús M. Míguez, Juan Miguel Mancera, José L. Soengas
A microtitre plate indirect enzyme‐linked immunoassay (ELISA) was developed for measuring plasma cortisol levels in rainbow trout Oncorhynchus mykiss, gilthead sea bream Sparus auratus sea bass Dicentrarchus labrax and Senegalese sole Solea senegalensis. Covalink microplates pretreat...... hiện toàn bộ
