Managing Water Quality When Transporting Live Fish Using Aquasend’s miniDOT® Clear Logger
Managing Water Quality When Transporting Live Fish Using Aquasend’s miniDOT Clear Logger No matter the fish species being transported, from largemouth bass to tilapia or even sturgeon, it is crucial to maintain proper oxygen levels and temperature when traveling with live fish. Each fish species has unique habitat requirements most often revolving around dissolved oxygen levels and temperature. ...

New Study Findings about Fish Gene Editing
Spermatogonial stem cells (SSCs) are a type of reproductive stem cells with self-renewal and differentiation potential in adult male gonads. Using spermatogonial stem cell transplantation (SSCT) technology, it is possible to achieve cross-individual or even cross-species "parthenogenesis", that is, the use of individual (or species) B to produce functional gametes of individual (or species) A. ...

Plasma cholinesterase activity as a biomarker for quantifying exposure of green sturgeon to carbaryl following applications to control burrowing shrimp in Washington State
Willapa Bay (Washington State, USA) has been one of the rare intertidal locations where large‐scale pesticide applications occur. Until recently, carbaryl was applied to control burrowing shrimp that decrease commercial oyster productivity. The Bay is critical habitat for green sturgeon (Acipenser medirostris), an anadromous species listed as threatened under the Endangered Species Act. ...

Assessing the risk to green sturgeon from application of imidacloprid to control burrowing shrimp in Willapa Bay, Washington. II: Controlled exposure studies
The activities of two species of burrowing shrimp have a negative impact on the growth and survivalofoysters reared on intertidal mudflats in Willapa Bay and Grays Harbor, Washington. In order to maintain viable harvests, oyster growers proposed the application of the neonicotinoid insecticide imidacloprid onto harvested beds for the control of burrowing shrimp. In test applications, water ...

Assessing the risk to green sturgeon from application of imidacloprid to control burrowing shrimp in Willapa Bay, Washington. I: Exposure characterization
Willapa Bay and Grays Harbor, Washington comprise the largest region of commercial oyster cultivation on the Pacific Coast. The activities of two species of burrowing shrimp impair growth and survival of oysters reared on the intertidal mudflats. In order to maintain viable harvests, the oyster growers have proposed controlling the shrimp by applying the insecticide imidacloprid onto harvested ...

Selenium tissue burden compartmentalization in resident white sturgeon (Acipenser transmontanus) of the san francisco bay delta estuary
High selenium (Se) loads into the San Francisco Bay‐Delta (SFBD) are bioaccumulated and biomagnified in food webs and can impair reproduction of resident oviparous animals such as white sturgeon. The objective of this study was to determine Se tissue burden in SFBD resident white sturgeon to assess Se bioaccumulation in different organs, including ovaries and liver where egg yolk precursor ...

Acute sensitivity of white sturgeon (Acipenser transmontanus) and rainbow trout (Oncorhynchus mykiss) to copper, cadmium, or zinc in water‐only laboratory exposures
The acute toxicity of cadmium, copper, and zinc to White Sturgeon (Acipenser transmontanus) and Rainbow Trout (Oncorhynchus mykiss) were determined for seven developmental life stages in flow‐through water‐only exposures. Metal toxicity varied by species and by life stage. Rainbow Trout were more sensitive to cadmium than White Sturgeon across all life stages with median effect concentrations ...

Chronic sensitivity of White sturgeon (Acipenser transmontanus) and rainbow trout (Oncorhynchus mykiss) to cadmium, copper, lead, or zinc in laboratory water‐only exposures
Chronic toxicity of cadmium, copper, lead, or zinc to White Sturgeon (Acipenser transmontanus) and Rainbow Trout (Oncorhynchus mykiss) was evaluated in water‐only exposures started with newly hatched larvae or about 1‐month‐old juveniles. The 20% effect concentration (EC20) for cadmium from the sturgeon tests was higher than the EC20 from the trout tests, whereas the EC20 for copper, lead, or ...

Nechako White Sturgeon Conservation Centre - Case Study
The Freshwater Fisheries Society of BC developed the Nechako White Sturgeon Conservation Centre to try to prevent extinction of this endangered species. Wild caught brood fish are held in the facility until spawning is complete. Controlled family groupings of young sturgeon are hatched in McDonald jars and reared for one year, first in 0.5 m3 and 1.5m3 combi tanks, then 8 m3 tanks before release. ...

Toxic effects of PCB126 and TCDD on shortnose sturgeon and Atlantic sturgeon
Exposure to chemical contaminants is often invoked to explain recruitment failures to populations of sturgeon worldwide, but there is little empirical evidence to support the idea that young sturgeon are sensitive at environmentally relevant concentrations. The authors used shortnose sturgeon, Acipenser brevirostum, and Atlantic sturgeon, Acipenser oxyrinchus, as models to investigate the ...
