“…Although there are well‐established husbandry techniques for crustacean and lobster larviculture (Aiken & Waddy, ; Burton, ; Wickins & Lee, ), research continues into improved management of facilities in an effort to reduce costs, and increase larval survival and growth rates. Most recently, this has included water quality and health management via non‐medicinal prophylactic treatments such as antibacterials and probiotics (Middlemiss, Daniels, Urbina & Wilson, ; Scolding et al., ), and novel larval rearing and ongrowing technologies, incorporated into both land‐based and sea container systems (Daniels et al., ; Drengstig & Bergheim, ; Shellfish Hatchery Systems, ).…”

Comparative survival and growth performance of European lobster larvae,Homarus gammarus, reared on dry feed and conspecifics

et al. 2017

A bottleneck of crustacean larval culture concerns nutrition and associated cannibalism in communal rearing systems, which impact on larval survival, development and growth. For early‐stage European lobster, Homarus gammarus larvae, feeding ecology and body composition are largely unknown. We initiated four progressive feeding experiments (novel feed types, feeding regime and feed size and cannibalism effects) on growth and survival, to inform and update husbandry protocols. Performance of larvae offered a dry commercial feed was not significantly different compared with a conventional wet plankton feed of the same ration and size grade (both within 600–1,000 μm). Further experiments found that the same ration of dry feed offered six times daily improved development and growth, over the conventional regime of three times daily. Small‐grade dry feed (particles: 250–360 μm) improved larval performance compared with a larger feed (360–650 μm). Larvae were also fed different proportions of dry feed and/or conspecifics in both communal and individual rearing systems (the latter preventing cannibalism via segregation). Individually reared larvae, fed only dead conspecifics, displayed the greatest survival (80%) to postlarvae. This underlines the impact of cannibalism on survival and nutrition in H. gammarus larviculture. A final experiment analysed H. gammarus zoea 1 composition, identifying deficiencies in ash and carbohydrate in lobster feeds. This suggests a need for a species‐specific, formulated dry feed for H. gammarus larviculture. Our research represents the first investigation of H. gammarus larval composition and dietary requirements and highlights decreased growth potential associated with providing nutrition solely from generic commercial feed.

“…(Fiore & Tlusty, 2005;Scolding, Powell, Boothroyd & Shields, 2012;Wickins, Beard & Child, 1995), and more recently, moist or wet (dead, sterilised) plankton preparations have been adopted by many European hatcheries (e.g. Daniels et al, 2015). However, given the highly cannibalistic nature of Homarus spp.…”

“…One approach may follow extensive sea‐based culture, in which juvenile lobsters obtain nutrition from natural food such as plankton and fouling organisms (e.g. Daniels et al, ; Powell & ELCE, ). An alternative approach may be to improve the design of land‐based rearing systems by reducing costs and benefitting from economies of scale (Drengstig & Bergheim, ; Powell & ELCE, ).…”

Comparative survival and growth performance of European lobster Homarus gammarus post‐larva reared on novel feeds

et al. 2019

One approach to ongrow juvenile European lobster, Homarus gammarus, is to utilize land based rearing systems, incorporating automated feeding, individual culture and provision of stable pelleted feeds, preferably using sustainable ingredients. We initiated three feeding experiments to investigate the general suitability of ingredients produced from seafood by-products as novel feeds for H. gammarus, in terms of promoting survival, development and growth of post-larval lobsters from post-larvae (PL) stage IV to the first juvenile stage (stage V). The first experiment was designed to screen an array of candidate, locally produced, novel protein sources on growth performance parameters. This initial experiment revealed that PL reared on a raw (i.e. wet, unprocessed shrimp) feed used as a reference showed superior performance to those reared on experimental feeds containing fishmeal, herring protein isolate or mussel meal; however, a novel type of shrimp meal, produced by flocculation from waste water, promoted the best PL performance of any experimental feed. A second experiment was designed to test the effect of drying method and to optimize the form of a wet shrimp reference feed used by lobster hatcheries. This showed that the performance of PL reared on experimental freeze-dried shrimp feed was not significantly different to those reared on the wet, unprocessed shrimp used as a reference feed.However, lobsters offered experimental oven-dried shrimp feed (with or without an immune supplement) resulted in significantly lower survival or growth performance. A third and final experiment was designed in an attempt to improve a candidate herringbased protein source, by supplementing with nutrients found in shrimp. However, the results showed that PL reared on the wet reference shrimp feed still showed superior growth and survival than those reared on a herring feed alone, or supplemented with additives found in shrimp meal (either glucosamine, astaxanthin or both supplements combined). The high survival and growth, low incidence of moulting problems and high availability of waste shrimp material, suggest that non-heat-treated shrimp products are a promising feed ingredient for post-larval European lobsters.

“…The feasibility of lobster SBCC systems has been tested using a variety of containers including one originally designed for rearing oyster sprat ( Fig. 1; manufactured by Pelegrin Y Manresa, S.L., Alicante, Spain) with good success (Uglem et al, 2006;Benavente et al, 2010;Browne et al, 2011;Daniels et al, 2015). These preliminary studies have established: 1) low energy costs, 2) zero feed costs 3) fixed unit cost of production (compared to an escalating cost against time in land based culture) and 4) good short term survival and growth rates.…”

“…Due to the cannibalistic nature and slow growth rates exhibited by the species, the lobster demands the use of a rearing system that has; individual compartments, is relatively inexpensive to construct and operate, is simple and inexpensive to maintain, is based on nonanthropogenic food supply, is self-cleaning, allows for sufficient feed and water exchange from naturally occuring sources, enables high stock density production while ensuring optimal growth and survival, and permitting easy access to livestock for inspection (modified from Drengstig and Bergheim, 2013). A potentially viable solution is a Sea Based Container Culture (SBCC) system because water quality and feed is supplied naturally by the sea and, capital investment and labour is minimal in comparison to land based techniques (Uglem et al, 2006;Benavente et al, 2010;Daniels et al, 2015). The feasibility of lobster SBCC systems has been tested using a variety of containers including one originally designed for rearing oyster sprat ( Fig.…”

The presented work describes the hydrodynamic assessment studies of a much needed technical innovation of Sea Based Container Culture (SBCC) as part of a semi-intensive, passive aquaculture culture system for farming the European lobster (Homarus gammarus). Factors that are known to influence growth and survival rates were obtained from previous literature, including flow rate, wave energy and motion characteristics; these factors defined performance criteria for SBCC containers.The internal flow velocities and external flow patterns for different SBCC container designs were measured and used to inform design decisions. Suitable graphical representations have been developed to assess SBCC containers on specific performance criteria. Oyster SBCC containers were found to provide stable motion characteristics but perform poorly against the lower velocity limit, indicating insufficient supply of Dissolved Oxygen (DO) to allow for optimal growth of European lobsters. Internal flow velocities were also measured on unfouled and fouled SBCC containers; results showed SBCC 2 would not provide enough DO with 66% biofouling coverage (66% biofouling replicates one year deployment) and triggered a redesign. SBCC 1 at 90° yaw angle of attack demonstrated all round good performance against upper and lower velocity limits and motion characteristics; thus showed greatest promise for cultivation of European Lobster. angle of attack provide best conditions.  Assessment of motion severity showed a circular container (Oyster SBCC) provides stable motion characteristics.  Normalised comparison provided fair comparison of performance criteria.
