Peer Reviewed Science November ’16

Welcome to volume six (November) of this digest of recent scientific discoveries for zoo keepers and aquarists!


Aquaculture – October 2016 Volume 465

Souza-Bastos L.R , Bastos L.P, Carneiro P.F, Freire C.A (2016) Acute salt exposure of the freshwater Characiformes: Pacu (Piaractus mesopotamicus, Holmberg 1887), Tambaqui (Colossoma macropomum, Cuvier 1818), and their hybrid Tambacu”. Aquaculture, 465:352-358

All three species can tolerate salt levels of 10psu for 1 hour without undue stress, useful for mild anaesthetics or bacterial treatment.


Aquaculture Research – October 2016 Volume 47 issue 11

Blanco A., Planas M. and Moyano F. J. (2016), Ontogeny of digestive enzymatic capacities in juvenile seahorses Hippocampus guttulatus fed on different live diets. Aquaculture Research, 47: 3558–3569.

Feeding the long-snouted seahorse a mixed diet of copepods and Artemia increased survival, final weight and final size over a diet of just Artemia.

Zoology- October 2016 Volume119 issue 5

Beckert M, Flammang B. E, Anderson E. J, Nadler J. H (2016), Theoretical and computational dynamics of an attached remora (Echenis naucrates), Zoology, 119: 430-438

Preferential attachment sites on large animals determined by sucker efficiency, not hydrodynamics.  Most hosts not capable of moving fast enough to dislodge remoras.  Large remoras less likely to be detached, suggesting age brings experience in hitchhiking.
