In order to collect novelties in this way, naturalists could engage in early morning walks through the market and dig through the stands of fish for sale; board fishing steamships and take advantage of the chance to collect those animals with no commercial value that appeared in the net and were generally thrown back; or visit the port when the fishermen were unloading the catch that had been classified by species.
De esta forma, para coleccionar novedades se podía recurrir a paseos matutinos por el mercado y hurgar en los puestos de venta; embarcarse en vapores pesqueros y aprovechar para coleccionar los animales sin valor comercial que aparecían en la red y que por lo general se devolvían al mar; o visitar el puerto cuando los pescadores descargaban la pesca obtenida y clasificada por especies.
