“…After the eggs have hatched, the female crabs moult and produce another clutch of eggs which become fertilized by males; they then extrude the fertilized eggs, which are carried beneath the abdomen until the next spring. The pelagic larval period lasts for about two to three months before they settle in shallow water in early summer (Epelbaum et al 2006).…”

Dietary astaxanthin supplementation for hatchery-cultured red king crab,Paralithodes camtschaticus, juveniles

We conducted large-scale production trials in Seward, Alaska, USA to investigate effects of dietary astaxanthin supplementation on survival, growth and shell colouration of recently settled juvenile (C1-C4) red king crabs (Paralithodes camtschaticus). We supplemented a control diet of commercial crustacean feeds with astaxanthin, and fed these diets to juvenile king crabs at densities of 2000 and 4000 crabs m À2 for 56 days. We assessed survival and growth by counting crabs and individually measuring carapace width and weighing crabs at the start and end of the experiment, and quantified crab colour (hue, saturation, brightness) in digital photographs. Diets containing astaxanthin had higher survival, suggesting that astaxanthin may provide nutritional or immune system benefits. Crabs had lower hue, higher saturation and lower brightness values when fed diets containing astaxanthin, suggesting that red king crab colouration is plastic and responds to diet. Astaxanthin is likely an important dietary component for hatchery or laboratory reared red king crab juveniles, and should be considered for aquaculture and other rearing of this and possibly other crustacean species.

“…There are two main factors that could explain that L. santolla larvae are more resistant to ammonia exposure: one factor is associated with its significant size compared with other decapods' larvae, and the other factor is that they do not depend on exogenous food sources (Amin et al 2003). Concerning the first factor, Campodónico (1971) reported that zoeae I of L. santolla have a carapace length of 3.75 ± 0.14 mm (total length of 6 mm; Boschi et al 1984), while this parameter in the same stage of related commercial species like Paralomis granulosa and Paralithodes camtschaticus is between 2.75 and 3.25 mm for the former, and 1.39 ± 0.03 mm for the latter (Epelbaum et al 2006;McLaughlin et al 2003). Furthermore, zoeae I of P. pelagicus, a more sensitive species to ammonia, presented values between 0.44 and 0.54 mm in carapace length (Josileen and Menon 2004).…”

Effects of ammonia on zoea I of the Southern King Crab, Lithodes santolla (Decapoda, Lithodidae) were analyzed through acute (96 h) and chronic (29 days in total) assays (seven total ammonia nitrogen (TAN) concentrations: 9, 15, 25, 41, 67, 110, and 182 mg L-1 , plus control). The estimated LC 50-96 h was 107.97 mg TAN L-1 (1.93 mg NH 3-N L-1), while the safe level of ammonia was 10.79 mg TAN L-1 (0.19 mg NH 3-N L-1). Survival was highest in the three lowest ammonia concentrations throughout 96 h (93.3%, 90% and 93.3% in 9, 15 and 25 mg TAN L-1 , respectively). In chronic assays, the percentage of survival decreased along with the exposure time and the ammonia concentration. Zoeaes mean life time tended to increase almost gradually with the increment of ammonia concentration. Mean molting time from zoea I to II was 4.06 days, while it increased from zoea II to III, and zoea III to the post-larval stage (6.00 and 8.39 more days, respectively) with ammonia concentration. The percentage of individuals that have molted in every molt stage tended to decrease while ammonia concentration increased. Therefore, the results obtained in the present study bring new information about ammonia toxicity in early stages of development of crab Lithodes santolla, an important commercial species of the Beagle Channel.
