“…This supports findings of the highly conservative of the process of oogenesis in the family Euphausiacea (Kikuno and Kawamura, 1983;Cuzin-Roudy, 1987b, 1993, 1997aCuzin-Roudy and Amsler, 1991;Cuzin-Roudy and Buchholz, 1999) for Meganyctiphanes norvegica and Euphausia superba. We did not directly adopt classifications developed by Cuzin-Roudy (1993) and Cuzin-Roudy and Buchholz (1999) because Minagawa and Sano (1997), using transmission electron microscopy in their gonad classification based on the work of Yano (1988), developed a classification that seems to be more specific because it distinguished morphological differences between oil globule and yolk granules in decapods. Although we were not able to observe all of the substages of this gonad classification, using resinembedded gonads stained with black sudan, we observed that N. simplex oocytes Oc3 had small oil glubules in the ooplasm during early vitellogenesis (endogenous), which was not previously observed in other euphausiids (Cuzin-Roudy and Amsler, 1991;Cuzin-Roudy and Buchholz, 1999).…”

a b s t r a c tInterbrood period, gonad development, and total lipid content throughout the oogenesis and spermatogenesis processes of the subtropical euphausiid Nyctiphanes simplex were studied. Specimens were collected during six oceanographic cruises in Bahía Magdalena (March, July, and December 2004) and in the Gulf of California (November 2005 and January and July 2007). Females attained first spawning when $ 7.5 mm total length (4 52 days old). Histological evidence indicates that N. simplex females have group-synchronous ovaries, able to produce four broods per gonadic cycle, since ovigerous females develop simultaneously in three and four distinct substages (Oc1, Oc2, Oc3, and Oc4) in their gonads. Once females mature, as shown by pale pink gonads, they may reabsorb their gonads in o 4 days. Direct observations indicate that after a variable resting period, the formation of oogonia to vitellogenesis takes $ 3 days, investing $ 8% (4-14%) of weight-specific carbon body weight to reproduction (lipid approach) with an average interbrood period of 10 days (range: 7-26 days, estimated by three distinct methods). About 22% of the ovigerous females in the metanauplius stage show gonad development in vitellogenesis, likely spawning between 7 and 9 days. The rest of the female population have an interbrood period that is considerably 4 10 days. Embryonic development in the ovigerous sac last o 3 days (16 1C), hatching always as nauplius (usually 100% hatching success); the metanauplii are released from the ovigerous sac in a median of 5 days after spawning. Although sacspawning euphausiid species may have comparatively lower total fecundity than broadcast-spawning species, they seem to have relatively similar reproductive effort and higher hatching success that increases larval recruitment rates, compared to similar size temperate broadcast-spawners. This partially explains why sac-spawners of the genera Nyctiphanes, Nematoscelis, and Pseudeuphausia are numerically dominant euphausiids in several highly eutrophic temperate, subtropical, and tropical ecosystems. N. simplex males have a continuous spermatogenesis after they attain size at first maturity; continuously allocating $ 5.4% of weight-specific carbon to reproduction, results that are significantly different than previous assumptions that euphausiid male spermatogenesis is energetically insignificant.

“…Some spiny lobsters are known to produce multiple broods, where the ovaries mature whilst the female is ovigerous (Minagawa & Sano, 1997). In the present study all of the ovigerous females possessed spent ovaries, including mid and late stage ovigerous females.…”

This paper describes the shery and reproductive biology for Linuparus trigonus obtained from trawl shermen operating off Queensland's east coast, Australia. The smallest mature female lobster measured 59.8 mm CL, however, 50% maturity was reached between 80 and 85 mm CL. Brood fecundity (BF) was size dependent and ranged between 19,287 and 100,671 eggs in 32 females from 59.8 to 104.3 mm CL. The relationship was best described by the power equation BF D 0.1107*CL 2:9241 (r 2 D 0:74/. Egg size ranged from 0.96 to 1.12 mm in diameter (mean D 1:02 § 0:01 mm). Egg weight and size were independent of lobster size. Length frequencies displayed multi-modal distributions. The percentage of female to male lobsters was relatively stable for small size classes (30 to 70 mm CL; 50.0 to 63.6% females), but female proportions rose markedly between 75 and 90 mm (72.2 to 85.4%) suggesting that at the onset of sexual maturity female growth rates are reduced. In size classes greater than 95 mm, males were numerically dominant. A description of the L. trigonus shery in Queensland is also detailed. RÉSUMÉCette étude décrit les caractéristiques de pêche et la biologie de la reproduction de Linuparus trigonus, obtenu par les pêcheurs au chalut au large de la côte orientale de Queensland, Australie. La langouste mature femelle la plus petite mesurait 59,8 mm CL, cependant, la maturité à 50% était atteinte pour les animaux mesurant de 80 à 85 mm CL. La fécondité (BF) était dépendante de la taille et comprise entre 19,287 et 100,671 oeufs chez 32 femelles de 59,8 à 104,3 mm CL. La relation a été le mieux exprimée par l'équation BF D 0,1107*CL 2;9241 (r 2 D 0,74). La taille des oeufs variait de 0,96 à 1,12 mm de diamètre (moyenne D 1,02 § 0,01 mm). Le poids et la taille des oeufs n'étaient pas liés à la taille de la langouste. Les distributions de fréquence de longueur ont montré une distribution multi-modale. Le pourcentage des femelles par rapport aux mâles était relativement stable pour les petites classes de taille (30 à 70 mm CL; 50,0 à 63,6% de femelles), mais les proportions de femelles ont augmenté de façon marquée pour les classes de taille de 75 à 90 mm (72,2 à 85,4%), suggérant

“…Mitosis mainly occurs in immature oocytes, while the mature oocytes are found in the metaphase of the first meiosis. This phenomenon indicates that the first meiosis occurs at maturation stage, and the second meiosis is completed after spawning (Yano, 1988;Minagawa and Sano, 1997;Zhu et al, 2005a). There is evidence that female E. carinicauda have the potential to carry more than one batch of eggs within a reproductive period.…”
