项目摘要

Intellectual Merit:Blue crabs (Callinectes sapidus) are an ecologically and economically important species in the Gulf of Mexico. In Chesapeake Bay and North Carolina, blue crabs have suffered from unexplained population crashes in recent years, purportedly due to increase fishing pressure and habitat degradation. Despite the importance of this species and the propensity for their stocks to crash, a realistic and predictive population model is still lacking for blue crabs.This RAPID project will use a metapopulation approach to understand and predict the population dynamics of blue crabs. Blue crabs spend their initial, larval, life-stages in the ocean then recruit to estuaries for their juvenile and adult stages. In the metapopulation model to be used, local dynamics in a patch (estuary) will be described and parameterized using fisheries data, remotely-sensed habitat quality estimates, and results from field experiments estimating cannibalism rates. The PIs will estimate connectivity (dispersal of larvae between estuaries) of the population with a particle tracking approach using a fine-scale, spatially-explicit ocean circulation model.When the Deepwater Horizon oil rig exploded on April 20, 2010, and began discharging several million gallons of oil into the Gulf, blue crabs were just beginning their spawning season. In this RAPID, the PIs propose to investigate the impacts of the oil and chemical dispersants on the larval stages, and ultimately on population dynamics, of blue crabs by sampling planktonic larvae at three ocean locations that vary in distance from the oil source. Results will estimate both lethal and sub-lethal effects of oil and dispersants on larvae. They will incorporate the extent and concentration of oil and dispersants into the particle-tracking model and use it to predict the effects of the oil spill on dispersal and recruitment for the entire Gulf of Mexico. To validate model results, the PIs will sample recruitment to estuaries over a wide stretch of the coastline, including areas unaffected, lightly affected and heavily affected by the spill. They will incorporate results into the metapopulation model to explore the long-term effects of the spill on the Gulf of Mexico blue crab population and its fishery.Broader Impacts:The PIs intend that results from this RAPID project will be used to inform fisheries policy so as to prevent collapses of blue crab fishery in the Gulf, especially in light of the recent oil spill. Dispersal information is lacking from current blue crab fishery assessments and may prove especially important now in helping to decide how to not exacerbate the effects of the oil spill. Their sampling will also be useful to document and consider the effects of oil and of dispersants on other commercially and ecologically important species with planktonic larvae, such as menhaden and shrimp. This project will provide interdisciplinary research experiences for several undergraduate and graduate students including field projects as well as computational experience.
智力优势:蓝蟹(Callinectes sapidus)是墨西哥湾的一种重要的生态和经济物种。在切萨皮克湾和北卡罗来纳州,蓝蟹近年来遭受了无法解释的种群崩溃,据称是由于捕捞压力增加和栖息地退化。尽管这个物种的重要性和他们的股票崩溃的倾向,一个现实的和预测的人口模型仍然缺乏蓝蟹。这个快速项目将使用集合种群的方法来了解和预测蓝蟹的种群动态。蓝蟹在海洋中度过它们的初始、幼虫和生命阶段,然后在河口招募它们的少年和成年阶段。在集合种群模型中使用,当地动态补丁(河口)将被描述和参数化渔业数据,遥感栖息地质量估计,并从现场实验估计同类相食率的结果。PI将使用精细尺度、空间上明确的海洋环流模型,通过粒子跟踪方法来估计种群的连通性(河口之间幼虫的扩散)。当深水地平线石油钻井平台于2010年4月20日爆炸并开始向墨西哥湾排放数百万加仑石油时,蓝蟹刚刚开始产卵季节。在这一快速行动计划中,研究人员建议通过在距离石油来源不同的三个海洋地点对浮游幼虫进行取样,调查石油和化学分散剂对蓝蟹幼虫阶段的影响,并最终对蓝蟹种群动态的影响。结果将估计石油和分散剂对幼虫的致死和亚致死影响。他们将把石油和分散剂的范围和浓度纳入颗粒跟踪模型,并利用它来预测石油泄漏对整个墨西哥湾的扩散和补充的影响。为了验证模型结果,PI将在海岸线的广泛延伸范围内对河口的补充进行采样,包括未受影响的地区,轻度影响和严重影响的地区。他们将把结果纳入集合种群模型,以探索泄漏对墨西哥湾蓝蟹种群及其渔业的长期影响。更广泛的影响:PI打算将该RAPID项目的结果用于制定渔业政策,以防止墨西哥湾蓝蟹渔业的崩溃,特别是鉴于最近的石油泄漏。目前的蓝蟹渔业评估缺乏扩散信息,现在可能证明在帮助决定如何不加剧漏油影响方面特别重要。它们的取样也将有助于记录和考虑石油和分散剂对其他具有重要商业和生态价值的鱼种(如鲱鱼和虾)的影响。这个项目将为几个本科生和研究生提供跨学科的研究经验,包括实地项目以及计算经验。
