A microwave energy meter to estimate energetic reserves in juvenile sturgeon J. Appl. Ichthyol. (IF 0.9) Pub Date : 2022-02-28 Matea A. Djokic, Joshua Heishman, Kevin M. Kappenman, T. Gibson Gaylord, Christine E. Verhille
Energetic stores can be metrics of fish health but are determined using lethal methods. Validation of non-lethal alternatives to estimate energetic stores would facilitate monitoring of wild fish of conservation concern, such as sturgeons. The Distell Fatmeter, a microwave energy meter, has been validated to estimate energetic reserves in a range of fish taxa but has not been tested on sturgeon. Therefore

Fishing opportunities for the deepwater cardinalfish (Epigonus crassicaudus) in the continental shelf break along central Chile J. Appl. Ichthyol. (IF 0.9) Pub Date : 2022-02-25 Luis A. Cubillos, Juan Vilches, Ciro Oyarzún, Daniela Yepsen
Spatial patterns in fish distribution determine most fishing opportunities and tactics learned by fishers. To determine fishing opportunities and recurrent fishing grounds of deepwater fish such as the cardinalfish (Epigonus crassicaudus) in the south-central zone of Chile, we analyzed records of fishing logs covering the period 1999–2007. Fishing trawls covered from Topocalma (34º06'S) to northwest

An assessment of gears for sampling shovelnose sturgeon in tributaries J. Appl. Ichthyol. (IF 0.9) Pub Date : 2022-01-23 Ryan N. Hupfeld, Gene Jones, Kirk Hansen, Hae H. Kim, Quinton E. Phelps
Despite potential importance of tributaries to Shovelnose sturgeon populations and historical declines range wide, limited population demographic and sampling efficiency information exists on shovelnose sturgeon populations in tributaries of the Upper Mississippi River. As such, we sought to evaluate the catch statistics of boat electrofishing, drifted trammel netting, and otter trawling for assessing

Identifying and characterizing juvenile lake sturgeon (Acipenser fulvescens, Rafinesque, 1817) occupancy hot spots within the St. Clair-Detroit River System J. Appl. Ichthyol. (IF 0.9) Pub Date : 2022-01-23 Aaron J. Mettler, Justin A. Chiotti, Andrew S. Briggs, James C. Boase, Robin L. DeBruyne, Edward F. Roseman, Richard Drouin
Over the past two decades, extensive monitoring has been conducted in the St. Clair – Detroit River System to describe spatial and temporal patterns of lake sturgeon (Acipenser fulvescens). To characterize spatial patterns in juvenile lake sturgeon (<1000 mm TL) based on survey collections, ‘hot spots’ were identified through optimized hot spot analysis (HSA). This HSA was then interpolated by inverse

Southernmost record of Elops smithi in the Southwest Atlantic. A tropical species in waters of Patagonia, Argentina J. Appl. Ichthyol. (IF 0.9) Pub Date : 2022-01-22 Nelson Dario Bovcon, Pablo Daniel Cochia, Gaston Andres Trobbiani, Mauro Belleggia, Kevin J. Jacobi, Agustin M. De Wysiecki, Daniel E. Figueroa, Alejo Joaquin Irigoyen
The presence of ladyfish Elops smithi in Patagonian waters is a new addition to the ichthyological fauna of the Argentinean Sea. This record represents a southward extension of its known distribution by 8 degrees of latitude, ~1500 km. It is another example of the more frequent arrival of tropical or subtropical fish species to Patagonian waters.
