Catch-and-release angling is growing as a tool for the conservation of fish stocks because it assumes that the impacts of angling are negligible. However, many studies have shown that catch-and-release can be stressful to the fish and even result in mortality. Bonefishing represents a popular catch-and-release fishery in the tropics and subtropics, with most anglers spending 6+ hours per day in full sunlight. To protect themselves, anglers typically employ sun protection in the form of liquid sunscreen and UV-blocking clothing. Exposure to chemicals contained in sunscreens may impose additional stressors on fish that are handled and subsequently released. In this study we conducted two separate experiments in the lab facilities in Cape Eleuthera, Bahamas. The first examined bonefish feeding behaviors in response to bait handled with zinc-based sunscreen, oxybenzone-based sunscreen, and no coating on the researcher’s hands. The second experiment quantified the effects of sunscreens and UV blocking gloves on the removal of fish’s protective mucus layer as a result of handling. We did not observe evidence of a change in feeding behavior when bait was handled with hands covered in sunscreen compared to wet hands. However, there was an increase in removal of protective mucus of bonefish when researcher’s hands were coated in oxybenzone containing sunscreen compared to researchers handling fish with wet hands. The results of this study indicate wet hands are the best way to handle fish when participating in catch-and-release angling. © 2015, Springer Science+Business Media Dordrecht.

A new species of cirolanid isopod, Bathynomus maxeyorum sp. nov., from The Bahamas, Western Atlantic, is described. This species represents the fourth species of Bathynomus to be described from the tropical and sub-tropical Western Atlantic. Bathynomus maxeyorum sp. nov. is characterized by 7 broad short pleotelsonic spines, with setation running along ~80% of the posterior margin of the pleotelson. Genetic analysis indicates a ~14% sequence divergence from the sympatric species Bathynomus giganteus.

Isopods are micropredators of deep-water sharks; however, their associations are poorly described in the scientific literature. We present the association of three isopod genera Aega sp., Aegaphales sp., and Cirolana sp. with two species of deep-sea shark, the Cuban dogfish (Squalus cubensis) and the sharpnose sevengill (Heptranchias perlo). Although limited conclusions can be drawn from this observation, it provides a novel association of micropredatory isopods with two poorly studied species of deep-water shark. © 2016 Senckenberg Gesellschaft für Naturforschung and Springer-Verlag Berlin Heidelberg
