 1. Reproductive development and maturity stage benchmarking in a freshwater teleost ruffe Gymnocephalus cernuus L. in Loch Lomond.
Treasurer JW Journal of fish biology J Fish Biol Reproductive development and maturity stage benchmarking in a freshwater teleost ruffe Gymnocephalus cernuus L. in Loch Lomond. 251-266 10.1111/jfb.14575 A wide range of classification schemes has been developed to describe reproductive development and stages in teleosts. These have been rationalised for clarity in recent years by Brown-Peterson et al. (Marine and Coastal Fisheries, 2011, 3, 52-70) and the WKASMSF (ICES, Report of the workshop for advancing sexual maturity staging in fish (WKASMSF), 2018) working groups. These have largely benchmarked classification schemes with examples from seawater fishes but have not been routinely applied to freshwater species. In addition, classification schemes developed to assess maturation of fish ovaries are either macroscopic and can be used in the field or histological for laboratory-based studies, and the two have rarely been coupled in the same classification scale or study. The present study reviews published maturation classifications for application to a freshwater teleost, ruffe Gymnocephalus cernuus L., sampled monthly over three annual cycles in Loch Lomond at locations in the extreme north and south ends of the loch. The gonado-somatic index and size frequency distribution of oocytes were used to verify the annual reproductive cycle and spawning of several egg batches. The study showed that a paired modified Percid scale (Treasurer & Holliday, Journal of Fish Biology, 1981, 18, 359-376) and the Rinchard scale (Rinchard & Kestemont, Journal of Fish Biology, 1996, 49, 883-894) gave an improved macroscopic and histological description of maturation compared with and benchmarked against previous ovarian developmental classifications for G. cernuus. The attributes of these various classifications are benchmarked and compared with the Brown-Peterson and WKMATCH scales, and the merits of these new notations are examined. © 2020 Fisheries Society of the British Isles.

4. Predation risk and competition affect habitat use of adult perch, Perca fluviatilis.
Henseler C, Nordström MC, Törnroos A, Snickars M, Bonsdorff E Journal of fish biology J Fish Biol Predation risk and competition affect habitat use of adult perch, Perca fluviatilis. 669-680 10.1111/jfb.14258 The aim of this study was to examine how the presence of a predator and an interspecific competitor influence the habitat use of adult perch (Perca fluviatilis; size: 15.1 ±?0.5 cm) when given the choice between two adjacent habitats. By conducting aquarium experiments, the habitat occupancy of P. fluviatilis was documented in the presence and absence of a predator (pike Esox lucius; size: 25.4 ±?2.1 cm) and a potential competitor (ruffe Gymnocephalus cernuus; size: 14.1 ±?0.3 cm) fish species. Two P. fluviatilis individuals generally shared the same habitat. In the presence of a conspecific, P. fluviatilis favoured the structurally more-complex, artificial macrophyte habitat over the less-structured rock and sand habitat, which in turn were used equally. In the predator- and competitor treatments, P. fluviatilis seemed to adapt their habitat use to the habitat occupancy of E. lucius and G. cernuus in the Macrophyte vs. Rock and, in the predator treatment, also in the Macrophyte vs. Sand habitat combination, by increasingly occupying a habitat that was used less by the predator or competitor species, respectively. This behaviour suggests that P. fluviatilis tried to avoid the other fish species by choosing a, in some cases less preferred, predator- or competitor-free habitat. This study emphasizes the importance of biological interactions illustrated by the potential of predation risk and competition to structure fish communities by influencing habitat use at small spatial scales. © 2020 The Fisheries Society of the British Isles.
