The pinnotherid Indopinnixa sipunculana Manning and Morton, 1987, represents the first record of Pinnotherelinae from the Indian Ocean. Quadrella reticulata Alcock, 1898 (Trapeziidae) is recorded from Pakistan for the first time The euryplacid Eucrate indica Castro and Ng, 2010, is formally recorded from Pakistan for the first time, with earlier records probably confused with E. alcocki Ng and Davie 2002 or E. crenata Alcock, 1900. The xanthid Leptodius gracilis (Dana,1852) is also a new record, being the second species of the genus reported from Pakistan.

Milne Edwards, 1840) (now Phallocryptus spinosa), Streptocephalus simplex, 1906, S. dichotomus Baird, 1860, S. maliricus Qadri and Baqai, 1956, S. lahorensis Ghauri and Mahoon, 1980, Branchipus schaefferi Fischer, 1834, Chirocephalus priscus Daday, 1910 and Artemia sp. In the present report these Pakistani species are reviewed. Streptocephalus dichotomus collected from Pasni (Mekran), housed in the Smithsonian National Museum of Natural History, USA (cat no. 213712) is inserted herein and another specimen of Streptocephalus sp., from a new locality, collected from Kalat not yet reported, is illustrated and described in this report, thus extending genus range further Northward. The need for further surveys directed towards getting the knowledge necessary in order to correctly understand and manage temporary pools- the elective habitat of large branchiopods is stressed.

The larvae were hatched out on December 07, 2005. The zoea I of Athanas dimorphus passed through II, III and IV zoeal stages within four days at room temperature: 23Ā°C-26Ā°C, in filtered seawater with salinity of 35-37ā° and pH 7.5-7.9. The developmental stages are described along with their illustrations and compared with the available descriptions of Athanas dimorphus larvae given by Gurney, 1927 for the first stage and Bhuti, et al., 1977 for first three stages. Thus, the fourth stage is being described for the first time not only in the species but in the genus Athanas.

The Pakistani material is more closely related to M. orientalis described by the earlier authors but does not fully correspond to any descriptions. It is therefore, only tentatively described here as M. orientalis; the material at hand is compared with previous descriptions of M. orientalis. Keywords

Fry of Cyprinus carpio were treated with 24-hrs median lethal concentration (LC50) of permethrin (35Āµg a.i./L) and Biosal (0.128 mg/L azadirachtin) separately under laboratory conditions. The results of enzyme activities of Biosal and permethrin treated carp groups were compared with that of control group. In Biosal treated carps, the activity of Alkaline phosphatase (ALP) showed significant (P<0.05) inhibition and Cholinesterase (ChE) activity showed insignificant (P>0.05) inhibition, while in permethrin treated carps the activities of both ALP and ChE showed significant (P<0.05) inhibition. Both Biosal and permethrin treated groups showed highly significant (P<0.001) increase in activity of Aspartate aminotransferase (AST) and significant (P<0.05) increase in the activity of Alanine aminotransferase (ALT) compared with the control group. The above results suggest that the sensitivity of ChE to permethrin is greater than that to Biosal in Cyprinus carpio fry.
