“…The distinct sex ratios verified for both species of the genus Lucifer in this study support the data of LÓPEZ (1966), who found a relation between males and females similar to that of L. faxoni in the region of Cananéia. However, in studies by ALVAREZ (1988) along the coast of Santos, and FUGIMURA et al (2005) in the bay of Sepetiba, RJ, a higher frequency of males was observed in relation to females, although their measurements were similar to those found in this study for L. typus.…”

Distribution of the species of Lucifer Thompson, 1829 in the subtropical South Atlantic between parallels 20º and 30ºs

The distribution of the species of Lucifer Thompson, 1829 (Decapoda: Luciferidae) in the South Atlantic Subtropical Gyre was assessed by the Brazil Transatlantic Commission in November and December 2009. The samples were collected at 83 stations on two profiles between Brazil and Africa (20 º and 30 ºS). Oblique hauls were performed with a WP-2 net up to 150 meters deep. A distinct sexual relationship was noted between the two species found and L. faxoni presented a significantly higher number of females relative to males 1:0.5 (X2 = 21.77, p = 0.0001). The L. typus sex ratio had significantly more males than females 1.86:1 (X2=50.84, p = 0.0001). The distribution of L. typus occurred in both the western and the eastern portions of the Mid-Oceanic Ridge. This distribution was significantly related to salinity (R2 = 0:13; F = 3.79, p = 0.009), which was higher in the western portion of the study area. In addition, the recordings of the two species were extended to the Atlantic Subtropical Gyre. Overall, Luciferidae shrimp were more common and abundant at the stations west of the Mid-Oceanic Ridge and L. typus was the most frequent and abundant species.

“…Sizes at first maturity (L 0.5 ), estimated here for B. faxoni (females: 6.53 mm, males: 6.74 mm), are similar to those found in Ubatuba, Brazil (females: 5.97 mm, males: 6.92 mm) [36]. In another locality of southern Brazil, López [32] calculated L 0.5 in terms of the pre-buccal somite length (females: 1.19 mm; males: 1.18 mm), which in this study, corresponded to 6.08 mm for females and 6.41 mm for males. Estimations of L 0.5 for L. typus (females: 8.16 mm; males: 8.63 mm) given in this study represented the first approach for the species.…”

“…Similarly, in the northern Gulf, Harper [16] found that the species showed their maximum abundance in August-September and decreased in October-November. In southern Brazil, field observations indicated that the species had continuous reproductive activity throughout the year, greater during the spring-summer period [32,33]. On the other hand, Lucifer typus was also recorded in all the sampling periods.…”

Population Structure and Seasonal Variability of two Luciferid Species (Decapoda: Sergestoidea) in the Western Gulf of Mexico

The population ecology of luciferids has been scarcely studied. This study examined the distribution and population parameters of Belzebub faxoni and Lucifer typus in the western Gulf of Mexico. Samples were collected using a Bongo net at 82 sampling stations during three periods (July, January, and October–November). Abundance data of species were subjected to a regression tree analysis to determine the main factors affecting their distribution. In addition, total length data of individuals were fitted to a logistic equation to estimate the size at first maturity. Food availability was the key factor affecting the distribution of B. faxoni, which exhibited its highest abundance over the inner shelf. In contrast, L. typus avoided low salinity waters (<35.9 psu), and its highest densities were found over the slope and oceanic areas. The sex ratio in B. faxoni was always biased towards females, but L. typus showed variable sex proportions. Several hypotheses attempting to explain these disparities are discussed. Size structure in B. faxoni favored small individuals in summer, the reproduction peak. In contrast, the L. typus population was always dominated by large individuals, probably transported by currents from the main hatching sites. Size at first maturity was higher in L. typus (females: 8.16 mm; males: 8.63 mm) than in B. faxoni (females: 6.53 mm; males: 6.74 mm). Information here provided may help to better understand the population dynamics of these species.

Feeding behavior of juveniles of the planktonic shrimp Lucifer faxoni Borradaile was studied in the laboratory under light and dark conditions. Newly-hatched nauplii and metanauplii of Artemio were used as prey organisms. The fecding raie of L. foxoni was dependent on prey size and prey density, but was not obviously affected by light or dark conditions. The capture of the prey tended to increase with longer exposure time to prey. The maximum ingestion rate was 17.28 and 13.40 nauplii.L. faxoni .d- , in the light and in the dark conditions, respectively.
