Colisa, the collection of ichthyological samples.

The collection of ichthyological samples, Colisa, results from the merging of historical samples collected by 3 INRA units (U3E in Rennes, ECOBIOP in Saint Pée sur Nivelle and CARRTEL in Thonon les Bains) and AFB-INRA Pole Gest’Aqua. These samples come from long term monitoring and research activities conducted by these units and from a national catch declaration scheme (angling and professional fishery). It consists of more than 200000 scales or other tissue samples of fish from 26 species collected in France over 50 years. Beyond age and growth, these samples, carrying DNA, allow genetic characterization of individuals or populations. Via microchemistry, they alos allow to characterize the trophic status and the environmental conditions of life of animals. The conservation of these tissues allow to investigate retrospective changes (global and local). Colisa is a part of BRC4env, one of the 5 specialized pillars of the French Research Infrastructure "Agricultural Resources for Research" (AgroBRC-RARe, http://www.enseignementsup-recherche.gouv.fr/cid99437/ressources-agronomiques-pour-la-recherche-rare.html) federating BRCs: animals as CRB-Anim, plant as CRB-Plantes, micro-organisms as CIRM, environmental resources as BRC4Env, and forests as CRB-Forets. BRC4Env includes BRCs and collections hosted by INRA, IRD, CIRAD, CNRS, technical and higher education institutions. (2018-09-20).

鱼类学样本集Colisa，是由法国国家农业研究院（INRA）下属3个研究单元（雷恩的U3E、尼韦勒河畔圣佩的ECOBIOP以及托南莱班的CARRTEL）与AFB-INRA Gest’Aqua平台所收集的历史样本整合而成的数据集。这些样本来源于上述单元开展的长期监测与研究工作，以及一项全国性捕捞申报计划（涵盖休闲垂钓与专业捕捞）。该数据集包含50余年间在法国境内采集的26种鱼类的超过20万枚鳞片及其他组织样本。除可用于分析鱼类年龄与生长特征外，这些携带脱氧核糖核酸（DNA）的样本还可用于个体或种群的遗传鉴定。通过微化学分析技术，还可对鱼类的营养状态及其生存环境条件进行表征。对这些组织的留存可供开展回溯性变化研究（涵盖全球与局地尺度）。Colisa是法国研究基础设施‘农业研究用农业资源’（AgroBRC-RARe，http://www.enseignementsup-recherche.gouv.fr/cid99437/ressources-agronomiques-pour-la-recherche-rare.html）下设5个专业化支柱之一的BRC4env的组成部分，该基础设施联合了多个生物资源中心（Biological Resource Center，BRC）：动物资源领域的CRB-Anim、植物资源领域的CRB-Plantes、微生物资源领域的CIRM、环境资源领域的BRC4Env以及森林资源领域的CRB-Forets。BRC4env涵盖由INRA、法国发展研究院（IRD）、法国农业国际合作研究发展中心（CIRAD）、法国国家科学研究中心（CNRS）以及各类技术与高等教育机构托管的生物资源中心与样本集。（2018-09-20）
