“…First, coastal environments such as estuaries and intertidal zones subject to large and frequent salinity fluctuations harbor many euryhaline fish species (Marshall, 2013). Second, euryhaline fishes are common in arid zones containing desert lakes and creeks (Brauner et al, 2012).…”

Salinity represents a critical environmental factor for all aquatic organisms, including fishes. Environments of stable salinity are inhabited by stenohaline fishes having narrow salinity tolerance ranges. Environments of variable salinity are inhabited by euryhaline fishes having wide salinity tolerance ranges. Euryhaline fishes harbor mechanisms that control dynamic changes in osmoregulatory strategy from active salt absorption to salt secretion and from water excretion to water retention. These mechanisms of dynamic control of osmoregulatory strategy include the ability to perceive changes in environmental salinity that perturb body water and salt homeostasis (osmosensing), signaling networks that encode information about the direction and magnitude of salinity change, and epithelial transport and permeability effectors. These mechanisms of euryhalinity likely arose by mosaic evolution involving ancestral and derived protein functions. Most proteins necessary for euryhalinity are also critical for other biological functions and are preserved even in stenohaline fish. Only a few proteins have evolved functions specific to euryhaline fish and they may vary in different fish taxa because of multiple independent phylogenetic origins of euryhalinity in fish. Moreover, proteins involved in combinatorial osmosensing are likely interchangeable. Most euryhaline fishes have an upper salinity tolerance limit of approximately 2× seawater (60 g kg −1). However, some species tolerate up to 130 g kg −1 salinity and they may be able to do so by switching their adaptive strategy when the salinity exceeds 60 g kg −1. The superior salinity stress tolerance of euryhaline fishes represents an evolutionary advantage favoring their expansion and adaptive radiation in a climate of rapidly changing and pulsatory fluctuating salinity. Because such a climate scenario has been predicted, it is intriguing to mechanistically understand euryhalinity and how this complex physiological phenotype evolves under high selection pressure.

“…Naast de diadrome (trek)vissen staan ook intergetijde en estuariene vissen bekend om hun plasticiteit in reactie op frequente saliniteit schommelingen, waaronder driedoornige stekelbaars Gasterosteus aculeatus (Marshall et al 2012). Zij zijn in staat om met een lage permeabiliteit van de huid en kieuw epitheel met efficiënte NaCl secretie te leven in een zoute omgeving.…”

“…Sommige soorten hebben zelfs de mogelijkheid om zout op te laan in geval van nood indien zij in een zoet systeem terecht komen. Ook zijn er soorten die bij grote schommelingen eerst een 'tolereer fase' ingaan alvorens er echt overgestapt wordt om te acclimatiseren (Marshall et al 2012). Een studie naar haring, kabeljauw en tarbot larven heeft aangetoond dat zij in staat zijn om water te drinken met diverse snelheden om te compenseren voor de saliniteit in het water (Tytler & Blaxter 1988).…”

“…In order to cope with these challenges, estuarine fishes must be able to switch their ion regulatory mechanisms to actively absorb ions across the gill and gut epithelium and excrete dilute urine (Edwards and Marshall, 2013;Marshall, 2013). However, these abiotic extremes combined with exposure to higher concentrations or more complex mixtures of chemical pollutants may overwhelm the physiological capacity of some estuarine species to respond to changing salinity conditions, ultimately resulting in reduced fitness and population declines (DeLorenzo, 2015;Schlenk and Lavado, 2011).…”

“…Cl -is extruded across the apical membrane by the cystic fibrosis transmembrane conductance regulator (CFTR) Cl -channel (Marshall and Singer, 2002). In addition, recent evidence suggests that water movement across the gill epithelium is regulated via changes in aquaporin-3 (AQP3) expression, which assists with the maintenance of basolateral cell hydraulic conductivity when fish are in fresh water conditions (Marshall, 2013).…”

choriogenins, and estrogen receptor esr1 -but not esr2a -in the liver within 72 hrs, and that these transcriptional changes return to pre-exposure levels within 12 days of the termination of 4-NP or E2 exposure. In sum, these findings validate the use of mRNA levels for several estrogen-responsive genes as accurate biomarkers for short-term 4-NP exposure in the arrow goby. In Chapter 2, I evaluated the effects of 4-NP and E2 exposures on the osmoregulatory ability of C. ios. I exposed adult arrow gobies to 4-NP (10 μg/L or 100 μg/L) or E2 (50 ng/L) for 14 days, and then transferred the fish from a 33 ppt salinity (control) environment to either 20 ppt, or 5 ppt conditions. Whole body water content was then measured, and the relative mRNA levels for the ion channels
