“…The loss of mucus, and injuries at the tail, adds to the stress of towing and handling. The general stress increases oxygen consumption, and alters the osmotic ability through a cortisol release (McCormick, 2001). This factor therefore adds to the alteration of the mucus coating which is an important factor in both gas exchange and osmotic integrity (Tesch, 2003).…”

Post fishing mortality of the glass eel was monitored in 2007 in the Vilaine estuary. The mortality of the glass eels varied from 2 to 82% (mean 42%) in the two days following the fishing. The mortality of samples collected by hand nets or from the trapping ladder was null. Alterations of the skin mucus were analyzed by the use of Indigo carmine. The mortality was significantly correlated with body injuries, but not to other environmental factors. The presence of a large injury on the body systematically led to the death of the glass eels, and among these dead glass eels, only 3.5% had no external injury. These results are discussed, along with the results from other estuaries, with a view to transport glass eels across Europe, with the objective of restoring the eel stock. RÉSUMÉLes tamis poussés semblent être responsables de blessures et de mortalités chez la civelle en estuaire de Vilaine (France) en 2007Les mortalités de civelles ont été suivies en 2007 dans l'estuaire de la Vilaine. Ces mortalités ont varié de 2 à 82 % (moyenne 42 %) dans les deux jours suivant la pêche. Les mortalités d'échantillons pêchés à l'aide de tamis à main ou capturés dans la passe à anguilles étaient nulles. Les altérations du mucus de la peau ont été analysées à l'aide de carmin indigo. Les mortalités étaient significativement corrélées aux blessures sur le corps mais pas aux facteurs de l'environnement. La présence d'une importante blessure sur le corps mène systématiquement à la mort des civelles, et au sein des civelles mortes, seules 3,5 % ne portent pas de blessure externe. Ces résultats sont discutés, avec ceux obtenus dans d'autres estuaires, par rapport à l'objectif de transporter des civelles en Europe en vue de restaurer le stock d'anguilles.

“…In teleosts, cortisol is essential for osmoregulation in both freshwater and seawater (23,25,55,56). Net renal tubular SO 4 2Ϫ secretion ceases (SO 4 2Ϫ clearance ratio Ͻ1) after acclimation of winter flounder to 10% seawater (69).…”

/HCO 3 Ϫ exchange at the brushborder membrane, tubular carbonic anhydrase (CA) activity, CAII protein, and a proportion of tubular SO 4 2Ϫ secretion that is CA dependent. CA activity is required for about one-half of this net SO 4 2Ϫ secretion but is also required for about one-half of the net reabsorption in bird proximal epithelium. A CA-SO 4 2Ϫ /anion exchanger metabolon arrangement is proposed that may speed both the secretory and reabsorptive processes. renal proximal tubule; transport metabolon INORGANIC SO 4 2Ϫ IS THE SECOND most abundant anion in the sea and one of the most abundant anions in vertebrate plasma, with concentrations varying among species from 0.3 to 1.8 mM. This large tetrahedral divalent anion can be obtained from the diet (83) or oxidation of the sulfur-containing amino acids cysteine and methionine (77). Sulfoconjugation reactions are the initial detoxification process for many endogenous (e.g., steroid hormones) and xenobiotic compounds and are required for the activation of numerous biological molecules (e.g., heparin, cholecystokinin, and gastrin) (59). SO 4 2Ϫ is a major component of glycosaminoglycans (dermatan sulfate, chondroitin sulfate, keratan sulfate, and heparan sulfate), which are structural components of numerous tissues, including cartilage, bone, myelin, and basal lamina (40 ]) in the renal tubule lumen reduces Ca 2ϩ and Mg 2ϩ reabsorption (66). RENAL SULFATE CLEARANCEThe kidneys are the major avenue for SO 4 2Ϫ excretion in vertebrates. Nearly all of plasma SO 4 2Ϫ is ultrafilterable in mammals (4), whereas 80% and 47% of plasma SO 4 2Ϫ are ultrafilterable in birds (71) and fish (75), respectively. Variation in the estimates of the ultrafilterable fraction of plasma SO 4 2Ϫ in vertebrates may arise from species differences or variations in method of determination. Urine content is determined by glomerular filtration, tubular reabsorption, and tubular secretion. This review will focus on the latter and will provide only a brief overview of tubular reabsorption because it has been described in detail elsewhere (2,51,52,57).Reabsorption of filtered SO 4 2Ϫ occurs primarily in the proximal tubule (35) secretion does not occur in these animals. SO 4 2Ϫ loading apparently has no effect on the saturable reabsorptive transport maximum for SO 4 2Ϫ (Tm SO 4 2Ϫ ) in the renal tubule of the human, dog, and frog (3,28,48). In contrast, Tm SO 4 2Ϫ in rats is reduced ϳ50% after plasma SO 4 2Ϫ loading, indicating that adaptive mechanisms are in place to depress reabsorption, thus increasing excretion (27). Similarly, in domestic fowl, Tm SO 4 2Ϫ decreases with plasma SO 4 2Ϫ loading, leading to the conclusion that a fraction of the excreted SO 4 2Ϫ is the result of tubular secretion (30). Thiosulfate, an inhibitor of SO 4 2Ϫ transporters,

“…Divergence in some of these behavioral traits has been observed among closely related species of several taxa, including Oncorhynchus (Hoar et al 1957;Houston 1957;Hoar 1958;Taylor and McPhail 1985;Hutchinson and Iwata 1997) and Gasterosteidae (Audet et al 1985). These behavioral traits are usually regulated by environmental factors, such as photoperiod and temperature, internal factors, such as hormones, and their interactions (McKeown 1984;Iwata 1995;McCormick 2001;Ramenofsky and Wingfield 2007). Therefore, elucidation of the genetic mechanisms by which the endocrine system of migratory and non-migratory species responds differently to environmental cues is indispensable for a better understanding of the genetic and molecular mechanisms underlying the variation in diadromous migration.…”

Closely related species of fish often exhibit different migration patterns. Even within species, anadromous and resident populations can be found in a diverse number of taxa. Although several environmental factors that regulate behavioral and physiological changes associated with fish migration have been identified, the genetic mechanisms underlying the variation in the ability to respond to these environmental cues in fishes that show different migratory behaviors are not well known. The three-spined stickleback Gasterosteus aculeatus (Linnaeus 1758) is a good model system for elucidation of the genetic basis for variation in migratory behaviors and other physiological changes associated with migration. First, the three-spined stickleback exhibits great inter-population variation in migration patterns. Second, genetic and genomic tools are now available for studying this species. In the present study, variation in the migration patterns among G. aculeatus populations and the recent progress in our understanding of the genetic and physiological basis for variation in traits important for G. aculeatus migration are reviewed.
