Sustainably Farming Lobsters
The Pockwood Pond site will be used for growing out post larval lobsters, until they are market size. Briefly, this involves pumping sea water into an array of tanks where the lobsters will be kept. The lobsters are then fed and monitored so that they grow quickly and produce excellent quality meat.
Water
The sea water will be sterilised and filtered before it is fed into the tanks in a continuous flow through manner. This sterilisation and filtration will be carried out to such a standard as to create water that is approaching pristine. The turn over rate of sea water in each tank will be sufficient to guarantee several complete water changes within a 24 hour period. This turn over rate will guarantee excellent water quality in the tanks and also exiting the tanks on the outflow side. However, as with all live stock operations, there will be some by products in the water on the outflow side. As with other live stock operations, these by products can be utilised to provide secondary productivity and this also affords some excellent bio-filtration to the outgoing water. Thus, a series of biological filtration stages after the lobster culture tanks, will be used to ensure that the water leaving the site is better quality than water entering. As a final belt and braces stop check on water quality the outflow will run through nearly 200 meters of ditch that is lined with mangrove trees (extra mangrove trees will be planted along this route and where ever possible on the seaward end of the eventual outflow). The bio-filtration steps onsite will be structured to ensure that water entering the existing drainage ditch will be of higher quality than water being pumped onto the site.
Feed
Lobster will be fed a diet consisting mostly of natural prey items. Some of this will come from sustainable sources elsewhere in the Caribbean and some will be collected as natural fouling from the gear used to harvest the post larval lobsters. In addition to this some of the feeds will be generated as secondary productivity from the culturing process. The feed input and feeding regime will be structured to ensure that lobsters are grown in a way that closely mirrors the natural process. |
