摘要

近年来,通过照片研究皮肤状况来评估放养鲸目动物健康状况的方法越来越受到重视。然而,人们很少关注鲸目动物皮肤状况、物种和身体状况之间的关系。为了探索西班牙西北海岸须鲸物种之间的这种关系,我们采用了一种非侵入性的方法,包括照片分析。在这项研究中,我们检测了 3 种鲸鱼(蓝鲸、长须鲸和小须鲸)的皮肤状况(包括外伤、外寄生虫和体外寄生虫、色素沉着病、皮肤损伤和解剖畸形)和身体状况(作为营养状况和健康指标的整体身体轮廓和形态)。这种方法有助于确定 29 个不同皮肤状况的子类别,并对 5 年内(2017 年至 2021 年)的身体状况进行评估。在我们的研究中,我们提出了将色素沉着、组织块突出和纹身样病变与 3 种须鲸的 "不良 "身体状况联系起来的证据。长须鲸更容易出现斑纹(发生率=17.7%),而蓝鲸更容易出现星斑(发生率=90.5%)。此外,我们还发现皮肤状况多样性与个体身体状况之间存在显著关系。我们的发现为更广泛地了解须鲸的健康状况提供了有价值的信息。有必要进行进一步调查,以深入了解所记录的皮肤状况的病因及其对个体生存的潜在影响。这项研究为我们正在进行的研究奠定了基础,旨在加深我们对这些发现的理解。

Relationship between skin and body condition in three species of baleen whales.

The assessment of free-ranging cetacean health through the study of skin conditions using photographs has gained prominence in recent years. However, little attention has been given to the relationships between cetacean skin conditions, species, and body condition. To explore this relationship among baleen whale species along the northwestern coast of Spain, we employed a non-invasive method involving photograph analysis. In this study, we examined skin conditions (including injuries, epizoites and ectoparasites, pigmentation disorders, skin lesions, and anatomical malformations) and body condition (overall physical contours and form, as an indicator of nutritional status and health) in 3 species of whales (blue, fin, and minke whales). This methodology facilitated the identification of 29 subcategories of distinct skin conditions and an assessment of body condition over a 5 yr period (2017 to 2021). In our study, we present evidence linking hypopigmentation, protruding pieces of tissue, and tattoo-like lesions to 'Poor' body condition in the 3 baleen whale species. Fin whales exhibited a higher susceptibility to mottling (prevalence = 17.7%), while blue whales were more prone to starbursts (prevalence = 90.5%). Additionally, we found a significant relationship between skin condition diversity and individual body condition. Our findings contribute valuable information to the broader understanding of the health status of baleen whales. Further investigations are necessary to delve into the etiology of the documented skin conditions and their potential implications for individual survival. This study serves as a foundation for ongoing research aimed at advancing our comprehension of these findings.
