Abstract

Abstract - A Morone saxatilis (Striped Bass) without horizontal black stripes, typically used to identify this species, was caught by an angler in the Miramichi River, near Chatham, NB, on 11 October 2020. The 6-year-old specimen measured 59 cm total length (56 cm fork length) and weighed 2.22 kg. Striped Bass are typically characterized by 7 to 8 dark horizontal lines expressed laterally. Stripes vary in pattern, including straight and parallel lines, broken or disjointed lines, or in the extreme, a checkerboard pattern. The specimen was identified as a Striped Bass morphologically using the arrangement of tongue dentition and the lack of antrorse spines on the pre-operculum, and molecularly using the barcoding region. This specimen appears to be the first Striped Bass recorded without stripes.

摘要-2020年10月11日，一名垂钓者在北卡罗来纳州查塔姆附近的米拉米奇河捕获了一只没有水平黑色条纹的Morone saxatilis（条纹鲈鱼），通常用于识别该物种。这只6岁大的标本全长59厘米（叉长56厘米），重2.22公斤。条纹鲈鱼的特征通常是横向出现7到8条深色水平线。条纹的图案各不相同，包括直线和平行线、虚线或不相交线，或者极端的棋盘图案。该标本通过舌列的排列和前盖上缺乏窦棘，并通过条形码区域进行分子标记，在形态学上被鉴定为条纹鲈鱼。这个标本似乎是第一个记录到没有条纹的条纹低音。

期刊介绍： The Northeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the northeastern portion of North America, roughly bounded from Virginia to Missouri, north to Minnesota and Nunavut, east to Newfoundland, and south back to Virginia. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion. The journal welcomes manuscripts based on observations and research focused on the biology of terrestrial, freshwater, and marine organisms and communities as it relates to their life histories and their function within, use of, and adaptation to the environment and the habitats in which they are found, as well as on the ecology and conservation of species and habitats. Such studies may encompass measurements, surveys, and/or experiments in the field, under lab conditions, or utilizing museum and herbarium specimens. Subject areas include, but are not limited to, anatomy, behavior, biogeography, biology, conservation, evolution, ecology, genetics, parasitology, physiology, population biology, and taxonomy. Strict lab, modeling, and simulation studies on natural history aspects of the region, without any field component, will be considered for publication as long as the research has direct and clear significance to field naturalists and the manuscript discusses these implications.
