A real-time PCR quantification method for QPX is beingverified for use as a diagnostic method. We are examining the bestgrowing conditions for hard clams in areas known to be infectedwith QPX while evaluating environmental conditions that maypromote the occurrence of the disease or have an environmentaleffect on the clam’s hemocyte function. A description of lobstershell disease and potential causes are being investigated.We continued our scientific project titled, “Feed the fish to feedthe people” to develop fish diets from native vegetation in Haiti.We worked in Haiti to develop field trials of our diets and findother protein sources to enhance diet formulation and transferredthe simple technology for manufacturing feeds to our Haitiancollaborators. Haitian feed trial results were similar to our MBLtrials last year; six pounds of previouslyunvalued vegetation yielded one poundof high quality fish protein. Our currentstudies focus on ways to turn agriculturalwaste into fermented protein for inclusionwith further improved fish diets.We have discovered that two clam speciesthat apparently do not cross-breed in theirnative habitats will cross-breed in thelaboratory. This may be important from acommercial perspective because one of thespecies, Spisula solidissima (Atlantic surf clam) supports a multimilliondollar fishery and is being developed for aquaculture. Theother species, Mulinia lateralis (coot clam), is easily cultured, hasa short generation time, and high reproductive rate. The hybridprogeny appear to grow faster and may prove to be advantageousfor aquaculture.Continued
