Data on spawning energetics and otolith microchemistry in female Ethmalosa fimbriata sampled in Senegal (Atlantic coast and Sine Saloum estuary)

In marine fish, stock complexity confers resilience to environmental variability and exploitation. Accurate stock identification is, therefore, a prerequisite to decipher the factors responsible for recruitment variation. We concatenated energetic reproductive investment with otolith microchemistry in order to delineate between stock spawning components in bonga shad Ethmalosa fimbriata in Senegal.

在海水鱼类中，种群复杂性赋予其对环境变异性及捕捞压力的韧性。因此，准确的种群识别是揭示补充量变化驱动因素的前提。本研究整合能量繁殖投入与耳石微化学分析，旨在区分塞内加尔海域邦加沙丁鱼Ethmalosa fimbriata种群中的产卵组分。
