<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>

Site Codes:<br />
BB = Bigelow Bight<br />
CN = Cape Neddick<br />
JL = Jeffery's Ledge<br />
KB and KR = Kennebunk River<br />
PR = Piscataqua River<br />
PRE = Piscataqua River Estuary<br />
SR = Saco River<br />
SRE = Saco River Estuary<br />
WH and WR = Webhanet River<br />
WI = Wood Island, near the mouth of the Saco River 20 individuals were measured for each species and the remaining were counted for biomass purposes. This accounts for the \"no measure\" seen in the notes column.</p>

本研究为研究人员与缅因湾渔业从业者的合作项目，旨在通过样带调查比奇洛湾从河口至内陆架区域的底层幼鱼分布与丰度情况。本项目将对相关底质与猎物可获得性进行表征分析，以明确该区域内的渔业生境资源。

本项目将采用沉积物剖面成像仪（sediment profile imager，简称SPI相机），该设备可从表面与剖面视角拍摄深度可达1英尺的底质及相关生物照片。该技术将与传统的鱼类采样方法（小网目陷阱网、桁杆拖网、变网目刺网）及底栖生物采样方法（Ponar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、底栖生物及底质情况，涵盖上述区域内受人类活动影响的位点，包括疏浚物料倾倒、处理后污水排放以及海底拖网作业等人类活动干扰位点。传统鳕鱼产卵场与索饵场以及保护区（杰弗里礁（Jeffrey's Ledge））均纳入本次调查范围。

本研究结果将提供亟需的数据，用于明确河口与内陆架区域的鱼类生境关联、这些生境的食物资源价值，以及它们对当前与既往人类活动干扰的响应情况。*摘自东北联盟项目数据库（Northeast Consortium Project database）*

### 采样位点代码：
BB = 比奇洛湾（Bigelow Bight）
CN = 内迪克角（Cape Neddick）
JL = 杰弗里礁（Jeffrey's Ledge）
KB和KR = 肯尼邦克河（Kennebunk River）
PR = 皮斯卡塔夸河（Piscataqua River）
PRE = 皮斯卡塔夸河河口（Piscataqua River Estuary）
SR = 萨科河（Saco River）
SRE = 萨科河河口（Saco River Estuary）
WH和WR = 韦布哈尼特河（Webhanet River）
WI = 伍德岛（Wood Island），位于萨科河河口附近。针对每个物种，我们会测量20个个体，其余个体则用于生物量统计，这也是备注栏中"未测量"项的由来。
