Chester zoo /​hus­bandry guide­lines


The Parosphromenus Project is help­ing Chester Zoo cre­ate Hus­bandry Guide­lines for BIAZA (British and Irish Assosi­a­tion of Zoos and Aquar­i­ums) and EAZA (Euro­pean Asso­ci­a­tion of Zoos and Aquaria)

In order for dif­fer­ent Zoos in Europe to be able to main­tain and keep pop­u­la­tions of Paros, it is essen­tial that guide­lines for best Hus­bandry Prac­tise is created.

This is not just describ­tions of expe­ri­ences, or guide­lines, this is at best a col­lec­tion of pre­cise data and infor­ma­tion, gath­ered over a period.

As a begin­ning, — a lot of writ­ten mate­r­ial has been given on from the Parosphromenus Project, — describ­tions of our known expe­ri­ence, as well as data con­nected with habi­tats — water con­di­tions, lev­els of ph, and other things. Not habi­tat data in terms of dis­tri­b­u­tion is nessesary.

But mainly we have pro­vided basic expe­ri­ence and knowl­edge about keep­ing paros in tanks, — food, breed­ing behav­iour, fry devel­op­ment etc.

To gather all this infor­ma­tion is a con­tin­u­ing pro­ces, and we invite every­one to take part in it by offer­ing their knowl­edge and spe­cific experience.
