Thank you Sheila and others The consensus is a clupeid, Sardinops neopilchardis, the striae on the opercular are diagnostic of this genus, of which we have only 1 species. I shall of course investigate comparative specimens, they are commonly sold as bait Mat Matthew Campbell CFG Heritage Ltd 132 Symonds Street PO Box 10 015 Dominion Road Auckland 1024 ph 09 309 2426 mobile 021 437 555 www.cfgheritage.com On 8/12/2016, at 11:18 PM, S Hamilton-Dyer <[log in to unmask]> wrote: Hi Mat, bearing in mind I am from the other end of the world, they remind me of shad (Alosa), have you already considered that group of 'herrings' yet?
