Dr Carly Daniels – Research and Development Manager

Carly, the Research and Development manager for the NLH, has over 13 years’ experience in the field. Carly pursued a career in Marine Biology from an early age, with a natural interest in the marine environment and the protection of its fascinating array of life-forms. Carly first came to the NLH in 2004  to conduct her Plymouth University undergraduate project, which aimed to improve the health of cultured lobsters through feed supplementation.

This stimulated an interest in lobster conservation, which led to Carly working with the hatchery to improve hatchery production and practical research, and undertaking a PhD(also with Plymouth) into optimising the rearing diets in lobster culture, which she completed in 2011. Carly now runs the hatchery’s rapidly growing research sector, leading investigations into hatchery culture techniques, mariculture on-growing, development of lobster diets, and the behaviour, physiology, bacteriology, histology, immunology and genetics of wild and cultured lobsters.

Carly has developed expertise in funding and managing collaborative and interdisciplinary research projects which generate impact in fisheries conservation and the aquaculture industry. As the Hatchery’s senior researcher, Carly leads a team of marine scientists and placement students who develop and undertake a diverse array of the NLH research within defined research projects, and is the principle investigator on Lobster Grower 1 and 2, Europe’s largest lobster research project.

These projects, jointly funded by Innovate UK and BBSRC, could revolutionise the impact of hatchery enhancement of wild lobster fisheries, as well as spearhead the development of a novel aquaculture sector. Carly has established the Hatchery’s reputation for lobster research on an international stage via the publication of 13 peer-reviewed scientific articles, and aspires to continue driving the charity’s growing contribution to marine conservation science.

Interests and expertise:

  • Sustainable fisheries and aquaculture
  • Stock enhancement
  • Ecological conditioning in cultured animals
  • Biotic supplementation
  • Dietary development
  • Alternative methods of sustainable aquaculture
  • Multispecies aquaculture

Full text Abstract

A parasite exhibiting Oomycete-like morphology and pathogenesis was isolated from discoloured eggs of the European lobster (Homarus gammarus) and later found in gill tissues of adults. Group-specific Oomycete primers were designed to amplify the 18S ribosomal small subunit (SSU), which initially identified the organism as the same as the ‘Haliphthoros’ sp. NJM 0034 strain (AB178865.1) previously isolated from abalone (imported from South Australia to Japan). However, in accordance with other published SSU-based phylogenies, the NJM 0034 isolate did not group with other known Haliphthoros species in our Maximum Likelihood and Bayesian phylogenies. Instead, the strain formed an orphan lineage, diverging before the separation of the Saprolegniales and Pythiales. Based upon 28S large subunit (LSU) phylogeny, our own isolate and the previously unidentified 0034 strain are both identical to the abalone pathogen Halioticida noduliformans. The genus shares morphological similarities with Haliphthoros and Halocrusticida and forms a clade with these in LSU phylogenies. Here, we confirm the first recorded occurrence of H. noduliformans in European lobsters and associate its presence with pathology of the egg mass, likely leading to reduced fecundity.

The heavy reliance of agriculture on pesticides, to assure quality and maximal productivity can result in downstream pollution of aquatic environments. The subsequent effects on non-target organisms are established for certain species, but remain largely unknown. This pollution can be problematic for aquaculture, which relies heavily on the use of natural water sources. The present study sought to develop a species specific biological assay that could be used to determine the suitability of water sources for use in aquaculture. The bioassay developed herein represents a simple low-cost technique that could be used to evaluate potential toxicity of any water-borne compound on H. gammarus. Additionally, this bioassay also has direct practical applications for assessing the suitability of water sources for rearing H. gammarus under culture conditions.
