Furunculosis in snow trout (Schizothoracinae) in Kashmir: first report

Incidences of furunculosis were reported in Schizothorax spp. (Schizothorax niger, S. esocinus, S. curvifrons and S. labiatus) in Wular Lake, Kashmir, from 2003 to 2005. The disease was reported during summer and winter months, but the percentage of infection was maximum during winter. Mortality rate ranged from 8 to 15%. Artificial challenge of Schizothorax spp. with Aeromonas salmonicida produced symptoms pertinent to furunculosis. The incidence of disease was the highest (13.87%) in December, and lowest (0.40%) in May and October. S. esocinus exhibited the maximum (44.48%) percentage of infection, while as S. labiatus exhibited the minimum (14.28%) throughout the study period. Haematological investigations revealed devastating changes in various blood parameters. Chemotherapeutic tests revealed complete recovery of the disease using 20 ppm oxytetracycline and 30 ppm streptomycin.

Isolation of Salmonella larochelle for the first time in India

The isolation of a new serotype, S. larochelle (6, 7: eh:1, 2), is reported in this communication. This serotype has not so far been reported from any source in this country. The serotype was isolated on November 27th, 1979 at Bombay from a market sample of frozen frog legs intended for domestic consumption.

Isolation of Salmonella roan for the first time in India

The isolation of Salmonella roan for the first time in India is reported.

Preliminary report on the first production of the crab stages of alimasag, Portunus pelagicus (Linnaeus)

An experiment was undertaken studying the early life history of Portunus pelagicus in order to obtain information of relevance to rearing techniques for crabs.

Fisheries studies on Lake George and Kazinga Channel: first quarter final report June/July 2001

FIRRI surveyed the fisheries of Lake George and Kazinga Channel between 20th June and 20th July 2001. This was the second survey FIRRI has conducted for the ILM project on the water system. The first survey was conducted during November 2000. These data, the analyses and accompanying reports contribute to baseline information for the fishery being collected with the support of ILM that is required for lakewide planning and management. Eight fish landing sites (6 on Lake George) namely; Kahendero, Hamukungu, Kasenyi, Kashaka, Mahyoro, Kayinja (2 on Kazinga Channel) namely; Katunguru -K and B fall within the focus of ILM and were surveyed during November 2000 and June/July 2001 over a three day period at each landing site in 2001 (Mahyoro 2 days). In November 2000, each landing was sampled once. FIRRI conducted a rapid FS and concurrently a CAS. All results are reported by landing site and then summed up (Global) for 8 sites on Lake George and Kazinga Channel.

First bi-lateral consultation meeting on Gulf of Mannar ecosystem, Rameshwaram, India, 5-6 September, 2011

Status papers on resources, livelihoods and ecosystem approach to fisheries in the Gulf of Mannar(GoM) were presented.Five priority initiatives were agreed: collaborative effort in conservation and management of charismatic species (e.g. dugong),capacity building and training,education and awareness building, strengthening of data collection and sharing of information.

First record of a spindle cowry Crenovolva (Ovulidae, Gastropoda) from Bulleji, Karachi, on the gorgonian coral Muricella sp. and with a note on their association

Attached to hard substrata on our shores occur the branching colonies of gorgonian corals of the genus Muricella (Fig. 1A, Pl. 1B, C, D). Since there is no report on this genus from Pakistan this report be taken as the first record from here. The family Ovulidae comprises several hundred species of marine gastropods, all of which appear to be obligate associates of cnidarians as stated by Robertson (1970) and Hadfield (1976); the present ovulid gastropod genus Crenovolva lives exclusively on the gorgonians (Morton, 1989). Tirmizi and Zehra (1984) recorded thirty-two families of gastropods from Pakistan, but not any representative of the Ovulidae, so the material at hand may be the first record from Pakistan. Since we are unable to reach to specific level the material is being reported as unspecified.

First experimental demonstration of low-cost VCSEL-intensity modulated end-to-end real-time optical OFDM signal transmission at 11.25Gb/s over 25km SSMFs

Low-cost, narrow modulation bandwidth, un-cooled VCSELs can be utilized to directly modulate 64-QAM-encoded 11.25Gb/s signals for end-to-end real-time optical OFDM transmission over 25km SSMF IMDD systems with excellent performance robustness. © 2011 Optical Society of America.

First real-time experimental demonstrations of 11.25Gb/s optical OFDMA PONs with adaptive dynamic bandwidth allocation.

End-to-end real-time experimental demonstrations are reported, for the first time, of aggregated 11.25Gb/s over 26.4km standard SMF, optical orthogonal frequency division multiple access (OOFDMA) PONs with adaptive dynamic bandwidth allocation (DBA). The demonstrated intensity-modulation and direct-detection (IMDD) OOFDMA PON system consists of two optical network units (ONUs), each of which employs a DFB-based directly modulated laser (DML) or a VCSEL-based DML for modulating upstream signals. Extensive experimental explorations of dynamic OOFDMA PON system properties are undertaken utilizing identified optimum DML operating conditions. It is shown that, for simultaneously achieving acceptable BERs for all upstream signals, the OOFDMA PON system has a >3dB dynamic ONU launch power variation range, and the BER performance of the system is insusceptible to any upstream symbol offsets slightly smaller than the adopted cyclic prefix. In addition, experimental results also indicate that, in addition to maximizing the aggregated system transmission capacity, adaptive DBA can also effectively reduce imperfections in transmission channel properties without affecting signal bit rates offered to individual ONUs.

The first quarter survey of the aquatic system and fisheries of the upper Victoria Nile, 6th -13th April 2006

The purpose of this present study therefore is to provide and update the AES Nile Power EIA baseline information on the ecology of the river ecosystem prior to the construction of the dam. The study is intended to provide a basis for evaluating the impact of the project on the river environment, the biological resources associated with it and fisheries socia-economics and the vector/sanitation status. This report presents the findings of the first sampling regime which was conducted between the dates of 6th-13th April 2006 and compared with the AESNP Environmental Impact Assessment findings of the second quarter carried out during 5th-14th April 2000.
