NEON Biorepository Fish Collection (Vouchers)

<p>This collection contains fish vouchers collected from wadeable streams and lakes (NEON sample class: fsh_perFish_in.voucherSampleID). Fish are sampled twice per year at lakes and wadeable stream sites, during spring and fall. Ten sampling reaches or segments are established at each site; with 3 fixed reaches sampled during every sampling bout and a random subset of 3 additional reaches or segments selected for sampling each year. Fish are sampled using a combination of electrofishing, gill-nets and mini-fyke nets. Field technicians identify fish to the lowest practical taxonomic level and then weigh and measure a subset of captured individuals before releasing. Only mortalities and individuals that require euthanasia due to injuries are vouchered. Vouchers that are in good condition are fixed in 10% buffered formalin preservative and then transferred to 70% ethanol or isopropanol for long-term storage. Vouchers that are in poor condition are not fixed but preserved in 95% ethanol. Specimens are archived in a temperature (17-18&amp;deg;C) and humidity controlled environment.

本数据集汇集了从可涉水溪流和湖泊（NEON样本类别：fsh_perFish_in.voucherSampleID）收集的鱼类凭证。鱼类在湖泊和可涉水溪流地点每年春季和秋季进行两次采样。在每个采样地点建立十个采样段落或区段；每次采样时，固定三个段落进行采样，并随机选择三个额外的段落或区段进行采样。鱼类采样采用电鱼、刺网和迷你鱼罟的组合方法。现场技术人员将鱼类鉴定至最低可行的分类等级，然后对捕获的个体进行称重和测量，并在释放前进行。仅对死亡个体和因受伤需要安乐死的个体进行凭证采集。状况良好的凭证使用10%缓冲甲醛固定剂进行固定，然后转移至70%乙醇或异丙醇中进行长期储存。状况不佳的凭证不予固定，但以95%乙醇进行保存。标本存档于温度（17-18℃）和湿度控制的环境中。以下链接提供相关协议和NEON相关数据产品。
