<p>\"This study represents a collaboration between researchers and members of the Gulf of Maine fishing industry to survey juvenile groundfish distribution and abundance along transects from estuarine through inner shelf areas of the Bigelow Bight. The project will characterize associated substrate and prey availability in order to determine fisheries habitat resources with the region. The project will feature the use of a sediment profile imager (known as an SPI camera), a device which takes photos of substrates and associated organisms both from a surface and from a profile view to depths up to 1 ft. This technique will be combined with traditional research sampling methods for fish (small mesh trap nets, beam trawls, and variable mesh gill nets) and benthos (Ponar grab sampler). The survey design will compare fish, benthos, and substrates between estuarine, nearshore and offshore areas, including sites within these zones that have been altered by human activities (i.e. dumping of dredge material, outfall of treated sewage, and bottom trawling). Traditional cod spawning and feeding grounds and a closed area (Jeffrey's Ledge) are included in the survey. Results of the study will provide much-needed data to determine estuarine and inner shelf fish habitat associations, the food resource value of these habitats, and their response to current and previous human alterations.\" <em>abstract from the Northeast Consortium Project database</em></p>

"比奇洛湾（Bigelow Bight）及邻近河口的幼龄底层鱼类分布与底栖生境关联研究"

文森特·巴尔扎诺（Vincent Balzano），商业渔民，渔船“北极星号”（F/V North Star）
理查德·麦肯齐（Richard MacKenzie），研究员
斯科特·奥林格（Scott Orringer），研究员

本研究为缅因湾（Gulf of Maine）科研人员与渔业从业者的合作项目，旨在沿比奇洛湾从河口至陆架浅海区域的样带，调查幼龄底层鱼类的分布与丰度。本项目将对相关底质与猎物可获得性进行表征，以明确该区域的渔业生境资源。
本项目将采用底质剖面成像仪（sediment profile imager，简称SPI相机），该设备可从表面及剖面视角拍摄底质与相关生物，拍摄深度可达1英尺。该技术将与传统鱼类采样方法（小网目陷阱网、桁杆拖网、变网目刺网）及底栖生物采样方法（波纳采泥器（Ponar grab sampler））相结合。
本调查设计将对比河口、近岸与远岸区域的鱼类、底栖生物与底质特征，涵盖受人类活动干扰的区域（如疏浚物倾倒、处理后污水排放、海底拖网捕捞区域）。调查范围还包括传统鳕鱼产卵与摄食场，以及封闭区域杰弗里斯浅滩（Jeffrey's Ledge）。
本研究结果将提供亟需的数据，以明确河口与陆架浅海鱼类与生境的关联、这些生境的食物资源价值，以及它们对当前及既往人类活动干扰的响应。
