“…The ability to maintain low plasma ion concentrations during the first few days after seawater exposure has been used to measure hypoosmoregulatory ability and to predict seawater survival (Parry, 1958;Conte and Wagner, 1965;Conte et al, 1966;Cl arke et al, 1978;Jackson, 1981).…”

“…Although size has been implicated as the primary effector of ontogenetic changes in osmoregulatory ability, few studies have attempted to separate the nonnally covarying properties of size and age.

Alligator Gars in Texas Coastal Bays: Long‐Term Trends and Environmental Influences

Recognition of the recreational and conservation value of the Alligator Gar Atractosteus spatula has spurred efforts to understand its biology, ecology, and status in river–reservoir systems throughout their range. However, Alligator Gars have also been found in the coastal bays that link these rivers to the Gulf of Mexico. Little is known about the species in saltwater environments or their potential role in coastal fish communities. For that reason, we analyzed 37 years (1975–2012) of standardized gill‐net catches of Alligator Gars in 10 Texas bays to characterize spatiotemporal trends in abundance and size structure and identify influential environmental covariates. Over 28,000 Alligator Gars (113–2,040 mm TL) were collected during 24,756 net‐nights of effort. The species was generally omnipresent both spatially and temporally; however, catch per unit effort varied by two orders of magnitude and was both cyclical and synchronous among bays. Trends in catch and size structure were consistent in most bays, which is indicative of stable abundance and dynamic rates. Current salinity and freshwater inflows, as well as catch rates, salinity, and freshwater inflows during the previous sampling year, explained significant proportions of the variation in catch in all but one system. Generally, periods of increased catch were associated with lower salinity and higher freshwater inflow, though Alligator Gars continued to be collected at salinities over 35‰. Analyses revealed that Alligator Gar catches in Texas bays were similar to or considerably greater than those of Bull Sharks Carcharhinus leucas, which are considered the most abundant top predator in these systems. The broad distribution of the Alligator Gars along the coast, coupled with its high relative abundance, highlight the need to understand the species’ role in coastal food webs and ecosystem function, with the ultimate goal of improving our ability to manage both Alligator Gar populations and coastal communities.

Effects of brackish water on growth, feed conversion and energy absorption efficiency by juvenile euryhaline and freshwater stenohaline fishes

Among six species of juvenile fishes (<6 months old), stenohaline species (channel catfish Ictalurus punctatus and goldfish Carassius auratus) had their highest specific growth rate (G) and most efficient food conversion ratio (E C ) and energy absorption efficiency (I E ) in fresh water. Three of the euryhaline species (rainbow trout Oncorhynchus mykiss, striped bass Morone saxatilis and Gulf sturgeon Acipenser oxyrinchus desotoi) had higher G and had more efficient E C and I E in 3 and 9‰ salinities than in lower salinities (fresh water and 1‰). For brown trout Salmo trutta (age 3-4 months), 9‰ was above the optimum level for G and E C . However, I E for brown trout was not significantly different at 3 and 9‰ salinities. Over the salinity range tested, channel catfish had the largest change in G, E C and I E , while changes for euryhaline species were relatively small. Although all species tested survived and grew in all treatments, salinities as low as 1‰ adversely affected the stenohaline species, and 9‰ adversely affected brown trout. 2001 The Fisheries Society of the British Isles
