An evaluation of potential diets for the culture of postpueruli spiny lobstersPanulirus argus(Palinuridae)

Abstract

Provision of a suitable feed is paramount for the ongoing success of spiny lobster culture. This study compared and evaluated the performance of seven diets for first instar juvenile spiny lobster Panulirus argus [5–6 mm carapace length (CL)] based on growth rates, survival, and feed conversion ratio. Results demonstrated that a seafood‐based juvenile formulation produced the fastest growth rate (3.49% weight gain day−1 and 0.90% CL increase day−1 over a 28‐day period). These growth rates were also reflected by a low feed conversion rate (3.04) for this formulated feed. Similar results were also obtained for juveniles fed a frozen seafood diet, however, frozen brine shrimp, Artemia salina (both enriched and un‐enriched), frozen enriched mysis shrimp, a dry pellet, and a meal‐based juvenile formulation did not produce consistent growth rates. Survival rates ranged between 38% and 85% and demonstrate that juvenile lobsters have better likelihoods of survival in captive culture environments compared to the wild. Although further nutritional refinement is recommended, the results from this research have significant implication for the possible expansion of juvenile spiny lobster growout to a larger scale.

Dietary protein quality differentially regulates trypsin enzymes at the secretion and transcription level in Panulirus argus by distinct signaling pathways

“…Research effort over the past decades has considerably increased our knowledge about the nutritional requirements of spiny lobsters (Williams, 2007) but feeding most species with formulated diets on a least-cost basis is still a challenge. Spiny lobster growth performance is relatively poor when they are fed on dry formulated diets unless high levels of krill meal and/or krill hydrolysate are included (Smith et al, 2005;Barclay et al, 2006;Cox and Davis, 2009). It seems that spiny lobsters cannot efficiently use proteins from common aquafeed ingredients (e.g.…”

A Global Review of Spiny Lobster Aquaculture

“…The results demonstrated that a seafood -based juvenile formulation produced the fastest growth rate over a 28 -day period. The composition of the seafood -based diet is given in Table 4 in an article by Cox and Davis (2009) . This is a good start, but a lot more testing needs to be undertaken.…”

“…The effect of feeding frequency on growth was studied by Cox and Davis (2006) , and Cox and Davis (2009) evaluated seven potential diets for the culture of post -pueruli of P. argus . The results demonstrated that a seafood -based juvenile formulation produced the fastest growth rate over a 28 -day period.…”

Ingestion of artificial diets with different textures as determined by the inert marker ytterbium oxide during culture of early-stage phyllosoma of the spiny lobster, Jasus edwardsii

“…Ritar, unpublished observations). There has been more success in the development of formulated feeds in adult and juvenile lobsters such as Panulirus cygnus (Glencross et al 2001), Panulirus argus (Cox & Davis 2006, 2009, J. edwardsii Johnston et al 2003;Ward et al 2003) and Homarus americanus (Bordner & Conklin 1981;Lim et al 1997). Diet formulation has also been investigated in culture of other decapod crustaceans such as the shrimp, Litopenaeus vannamei (Forster et al 2003), prawn, Penaeus monodon (Glencross et al 2002), and crab, Cancer magister (Bordner 1989).…”
