Length-weight relationships (LWRs) for six fish species caught from tidepools in an intertidal rocky shore in the Gulf of Cadiz are presented. This study presents the first data on LWR for Clinitrachus argentatus (WT = 0.0069 * TL^3.077), Coryphoblennius galerita (WT = 0.0051 * TL^3.409), and Parablennius incognitus (WT = 0.0090 * TL^3.113) outside the Mediterranean Sea and adjacent eastern waters. The data of LWRs for juveniles of Symphodus roissali (WT = 0.0117 * TL^3.091), Serranus scriba (WT = 0.0165 * TL^2.881), and Diplodus cervinus (WT = 0.0152 * TL^3.060) are also presented for first-time. Due to fish body shape may vary during growth in relation to size, studies covering a specific size range relating to life stage can be useful to estimate the LWRs for different development phases. The findings of this study fill the gap in LWRs data for immature fish in S. roissali, S. scriba and D. cervinus. Moreover, because intertidal zones and their adjacent subtidal areas represent nursery grounds for species that eventually recruit to coastal fisheries, the LWRs estimates for other species can also help to understand the population dynamics and conservation for native fish species.

介绍了在加的斯湾潮间带多岩石的海岸上从潮池中捕获的六种鱼类的长度-重量关系（LWR）。本研究提出的LWR第一数据Clinitrachus argentatus（WT = 0.0069 * TL ^3.077），Coryphoblennius galerita（WT = 0.0051 * TL ^3.409），和Parablennius incognitus（WT = 0.0090 * TL ^3.113地中海以外）和邻近的东部海域。Roissali Symphodus roissali（WT = 0.0117 * TL ^3.091），Serranus scriba（WT = 0.0165 * TL ^2.881）和Diplodus cervinus（WT = 0.0152 * TL ）幼虫的LWR数据^3.060）也首次出现。由于鱼的体形可能在生长过程中随大小而变化，因此涉及生命周期的特定大小范围的研究可能有助于估算不同发育阶段的轻水堆。这项研究的结果填补了S. roissali，S. scriba和D. cervinus的未成熟鱼LWRs数据的空白。此外，由于潮间带及其相邻的潮下带代表了最终招募到沿海渔业的物种的育苗场，因此轻水堆对其他物种的估计也有助于了解当地鱼类的种群动态和保护。
