Reproduction and embryonic development of monkeyface prickleback Cebidichthys violaceus in captivity
Journal of Fish Biology, EarlyView.Abstract Understanding the sequence of embryonic and larval development and the factors necessary to induce reproduction in captivity are critical for developing new species for commercial or conservation aquaculture. In this study, we describe the adult reproductive behaviours and development of eggs, embryos and early larvae of captive monkeyface ...

Journal of Fish Biology, EarlyView.Abstract The plainfin midshipman (Porichthys notatus Girard, 1854) is a toadfish with two distinct reproductive male tactics: ‘guarder males’ and ‘sneaker males’. These two tactics are anatomically, physiologically and behaviourally distinct from one another at sexual maturity, but it remained unclear whether these two male types remain fixed or ...

The role of otolith size in hearing – Insights from cichlid fishes
Frontiers in Marine Science, 2015 Otolithic end organs in fishes function as accelerometers and are involved in the senses of balance and hearing (e.g. Popper et al. 2005). Otolith mass and shape are likely decisive factors influencing otolith motion, but while it is largely unknown how ...

Journal of Fish Biology, EarlyView.Abstract Yellowstone cutthroat trout Oncorhynchus virginalis bouvieri in Yellowstone Lake are the focus of intensive conservation efforts due to the threat of predation by invasive lake trout Salvelinus namaycush. Suppression gillnetting has reduced the abundance of predatory lake trout, and the Yellowstone cutthroat trout population is recovering ...

Otolith Morphology of Small Yellow Croaker (Larimichthys polyactis)in Yangtze River Estuary and the Application in Biology Study [PDF]
, 2016 耳石为硬骨鱼类内耳中的钙化结构，主要起到听觉及平衡鱼类身体的作用。目前耳石形态学已成为国内外鱼类学研究的热点，涉及鱼类年龄与生长、种群划分、群体识别、生活史反演等多个领域。本研究以长江口小黄鱼（Larimichthyspolyactis）为研究对象，研究耳石形态与体长、体质量的关系，探讨耳石生长与小黄鱼特殊生长阶段的关系，且从生物学及耳石形态学角度综合探讨小黄鱼春季群体及秋季群体间的差异，并就耳石形态在两个不同生态群体间的识别作用及年龄鉴定作用进行初步探究，旨在丰富小黄鱼耳石形态学研究 ...

Journal of Fish Biology, EarlyView.Abstract The European pilchard, Sardina pilchardus, is a key small pelagic fish sustaining Mediterranean ecosystems and fisheries. This study represents the first comprehensive biological and population dynamics assessment of the European pilchard by applying the length‐based spawning potential ratio (LB‐SPR) approach to S.

Journal of Fish Biology, EarlyView.Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Journal of Fish Biology, EarlyView.Abstract Anadromous Arctic char (Salvelinus alpinus) and northern form Dolly Varden (Salvelinus malma malma) are highly valued by Indigenous communities in northern Canada. Rapid, ongoing environmental changes are affecting populations of both of these iteroparous species, and understanding variability in life‐history tactics is essential for ...
