Abstract

The recreational fishery for Barred Sand Bass (Paralabrax nebulifer) has recently shown declines in catch prompting a need for updating life-history attributes. The objective of this study was to provide a more extensive and current examination of Barred Sand Bass age and growth. Fish were collected from the southern California bight from 2011 to 2015. Using Akaike Information Criteria analysis we determined that the three-parameter von Bertalanffy growth model was the best fit out of the four tested models (Gompertz, Logistic, Power, and von Bertalanffy). Males grew slightly quicker than females (k, males = 0.10, females = 0.08). Males and females did not differ in length, weight, or the length-weight relationship. We also validated yearly banding of Barred Sand Bass with oxytetracycline marking of two fish in captivity for one year. Location of the first annulus was also validated with otolith diameter measurements. Finally, we compared the current study to a past 1990’s study and observed different growth parameters. The growth difference after thirty years showed that possible fishing pressure and environmental factors might have influenced changes in growth. This study provides current information on age, growth over time and, otolith morphometrics, for Barred Sand Bass.

南加州湾条纹沙鲈鱼年龄和生长的验证

Barred Sand Bass（Paralabrax nebulifer）的休闲渔业最近显示出捕捞量的下降，这促使人们需要更新生活史属性。这项研究的目的是提供一个更广泛和最新的检查Barred Sand Bass年龄和生长。2011年至2015年，人们从南加州湾采集了鱼类。使用Akaike信息标准分析，我们确定三参数von Bertalanffy增长模型是四个测试模型（Gompertz、Logistic、Power和von Bertalanffy）中最适合的。雄性的生长速度略快于雌性（k，雄性=0.10，雌性=0.08）。雄性和雌性在长度、重量或长重关系上没有差异。我们还验证了用土霉素标记圈养一年的两条鱼的Barred Sand Bass的年度条带。第一个环的位置也通过耳石直径测量进行了验证。最后，我们将当前的研究与上世纪90年代的研究进行了比较，并观察到了不同的生长参数。三十年后的生长差异表明，可能的捕鱼压力和环境因素可能影响了生长的变化。本研究提供了关于Barred Sand Bass的年龄、随时间的生长以及耳石形态计量学的最新信息。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
