Dining in the Deep: The Feeding Ecology of Deep-Sea Fishes
Annual Review of Marine Science ( IF 14.3 ) Pub Date : 2017-01-03 00:00:00 , DOI: 10.1146/annurev-marine-010816-060543

Deep-sea fishes inhabit ∼75% of the biosphere and are a critical part of deep-sea food webs. Diet analysis and more recent trophic biomarker approaches, such as stable isotopes and fatty-acid profiles, have enabled the description of feeding guilds and an increased recognition of the vertical connectivity in food webs in a whole-water-column sense, including benthic-pelagic coupling. Ecosystem modeling requires data on feeding rates; the available estimates indicate that deep-sea fishes have lower per-individual feeding rates than coastal and epipelagic fishes, but the overall predation impact may be high. A limited number of studies have measured the vertical flux of carbon by mesopelagic fishes, which appears to be substantial. Anthropogenic activities are altering deep-sea ecosystems and their services, which are mediated by trophic interactions. We also summarize outstanding data gaps.

在深处用餐:深海鱼类的饲养生态

深海鱼类约占生物圈的75%,是深海食物网的重要组成部分。饮食分析和更近期的营养性生物标志物方法(例如稳定的同位素和脂肪酸谱)已经能够描述饲料协会,并从全水柱意义上(包括底栖中上层)认识到食物网中的垂直连通性得到了越来越多的认识。耦合。生态系统建模需要有关进食速度的数据;现有的估计数表明,深海鱼类的单人摄食率低于沿海和上层鱼类,但总体捕食影响可能很大。有限数量的研究已经测量了中生鱼类的垂直碳通量,这似乎很重要。人为活动正在改变深海生态系统及其服务,由营养相互作用介导。我们还总结了突出的数据差距。
