En francais au dessus From: Laurence Evans [mailto:ecotao@yahoo.com] Sent: 15 June 2013 08:50 To: William Leschen Subject: Re: [Sarnissa] Womens Group Cage tilapia farming in Siavonga Zambia Hi William This is south of Jeddah in Saudi Arabia, with a salinity between 40 and 48 ppt. We imported bulk knotless net rolls from China and used a commercial sewing machine to make the nets on site. We had 2 staff members from Nepal who knew how to sew. Fingerlings are moved to growout ponds and fed commercial pellet. Growout is to market size - anything between 0.5 and 2 kg. from 15 grams to 750 grams takes about 200 days in summer and at these salinities. Regards, Laurence. Salut William C'est au sud de Jeddah en Arabie Saoudite, avec une salinité entre 40 et 48 ppt. Nous avons importé en vrac rouleaux net sans noeuds en provenance de Chine et utilisé une machine à coudre commerciale pour faire les filets sur le site. Nous avons 2 membres du personnel du Népal qui savaient coudre. Les alevins sont transférés dans les étangs de grossissement et de la Fed commercial granulés. Grossissement est de la taille du marché - rien entre 0,5 et 2 kg. à partir de 15 grammes à 750 grammes prend environ 200 jours en été et à ces salinités. Cordialement, Laurence.

We did not test the upper limit. 5220 fish in one cage, 3m x 4.8m x 1.2m @ 26.7grams = viable biomass Nets were manually cleaned during grading. Fish were typically held for 50 days. Quantity Parameter Note 141 kg per cage Estimated maximum biomass at size 17.3 m3 volume of cage 8.2 kg/m3 with 3 airlifts for aeration per cage 27.0 grams maximum fish weight regards Laurence aqua@ecotao.co.za<mailto:aqua@ecotao.co.za> ________________________________ From: Titus Phiri <titobandulo@gmail.com<mailto:titobandulo@gmail.com>> To: sarnissa-african-aquaculture@lists.stir.ac.uk<mailto:sarnissa-african-aquaculture@lists.stir.ac.uk> Sent: Friday, June 14, 2013 7:50 AM Subject: Re: [Sarnissa] Womens Group Cage tilapia farming in Siavonga Zambia William, I would like to know the stocking density for these cages and how long has the fish been in the cages. Were the cages installed in Lake, reservoir or river? Do you mind posting a picture of the cage on this forum? Do you see any prospects of sustainability for farmers after the sponsoring organisations pull out? This is a very good initiative for women.
