Influence of a fish bacterium Lactobacillus sp. on the production of swordtail xiphophorus helleri (Heckel 1848)

The influence of a fish gut bacterium Lactobacillus sp on the production of swordtail Xiphophorus helleri was studied for a period of one year. The Lactobacillus sp P21 produced bacteriocin-like inhibitory substance and exhibited wide spectrum of action against Aeromonas hydrophila, Bacillus spp, Pseudomonas spp and Citrobacter freundi in vitro. The growth performance of X. helleri reared in the presence of Lactobacillus P21 at 106/ml rearing water was better than the control. The total plate counts, total MRS agar counts and the counts of motile aeromonads, presumptive pseudomonads, lactose fermenters and lactose non-fermenters in the gut of probiotic group were comparatively low than the control. On day 60 the count of Lactobacillus sp P21 was observed to be log 5.28/g in the gut of X. helleri indicating colonization of this bacterium in the gastrointestinal tract. The fecundity of X. helleri was in the range of 9-134. On average, it produced from 39.42±18.72 fry/female in control group to 53.00±23.57 fry/female in probiotic group. The increase in average fecundity in probiotic group over the control group was about 25%. There existed significant difference between probiotic group and control in respect of average fecundity/female (p<0.02), average number of fry survived /female (p<0.006) and average number of fry dead/female (p<0.029). The results of the present study demonstrated that the rearing of X. helleri in probiotic-enriched water have growth inducing ability and favourably influenced the reproductive performance in terms of high fecundity, high fry survival, reduced fry mortality and reduced fry deformity.

Morphometric relationships of spineless cuttlefish, Sepiella inermis (Orbigny, 1848) from Mumbai waters

The relationships of various morphometric characters with dorsal mantle length (DML) of Sepiella inermis from Mumbai waters was established. The coefficient of correlation (r²) for various morphometric characters against dorsal mantle length ranged from 0.747 to 0.942 indicating high degree of relationship among the characters compared. The regression of characteristics obtained by least squares method for S. inermis indicates that the characters have positive allometric growth.

The identity of Schizothorax griseus Pellegrin, 1931, with descriptions of three new species of schizothoracine fishes (Teleostei: Cyprinidae) from China

The identity of Schizothorax griseus Pellegrin, 1931, is clarified and the species redescribed. Three new species previously identified as S. griseus are described: S. nudiventris, from the Lancang Jiang, China; S. heterophysallidos, from the Nanpan Jiang

南美白对虾（Penaeus vannamei Boone,1931)卵子质量的形态学评估

1）本文描述了南美白对虾正常的卵子形态及发生特点，以及受精卵和非受精卵的形态学鉴别方法。2）从生产的角度出发提出了评估卵子质量的五项指标：同批卵子规格的一致程度，卵子的沉降速度，孵化膜的抗变形能力，4－8细胞期的分裂特点，扩膜卵在同批卵中所占的比例。除此外，对于亲虾持续产卵与所产卵子质量的关系等也作了相应的探讨。

Women artists of the international avant-garde: the case of "Abstraction-Création" (1931-1936)

Women’s contribution to abstract art in the interwar period is a subject that, to date, has received very little attention. In this article we deal with the untold story of the participation of women artists in Abstraction-Création, the foremost international group dedicated to abstract art in the 1930s. Founded in Paris in 1931, the group took on the work of two previous collectives to become a platform for the dissemination and promotion of abstract art and consisted of around a hundred members. Twelve of these were women, whose writings and works were published in the group’s annual magazine, abstraction creátion art non figuratif (1932-1936), and who participated in a number of the group’s exhibitions. Compared to what had occurred in previous groups, the participation of women, although reduced in number, was comparable to that of the male artists and being members of the group had a generally positive impact on the women’s careers. However, all this came at the expense of relinquishing any gender specificity in their work and the public presentation of it, and demonstrates that the normalization of women’s contributions to the avant-garde could only be brought about alongside a questioning of the more dogmatic views of modernity.

Playing with the ‘Erbe’: The Legacy of the Songs of the 1848 Revolution in the GDR

After the twelve-year rupture caused by the Nazis, in the Soviet zone after 1945 attempts were made to reconnect with the traditions of workers’ songs and critical folk songs that were viewed as the cultural heritage of the communist movement. One of these ‘repertoires’ of song was that of the 1848 Revolution. In the 1950s GDR researchers such as the Germanist Bruno Kaiser, the musicologist Inge Lammel and in particular the folklorist Wolfgang Steinitz made substantial contributions to the collecting and publication of the 1848 songs. Their work provided an important reference point for the singers of the German folk song revival in the GDR from the late 1970s onwards. As the cases of groups such as Folkländer and Wacholder showed, theirs was a particularly creative appropriation of the revolutionary Erbe that involved performing protest songs of the past as if they were criticising the present.

AHRC-DFG Project "Songs of the Revolution of 1848 and their Reception History in Germany"

This on-line project consists of commentaries and critical editions of the songs of the 'Vormaerz' and the 1848 Revolution which have shaped the cultural memory of this period in Germany. Looking at both textual and musical developments the research deals with the history of reception of key 1848 songs by established as well as anonymous poets. These together have formed an enduring corpus in the repertoires of singers of German political song. One of the main findings is how songs are not static: they evolve musically and textually and can undergo changes of function during a process of historical reception which is often ideologically motivated.
