Taxonomy-Marine Prawns of India
No full textThe penaeoid prawns (Superfamily
Penaeoidea) constitute a diverse group of marine
decapods with over 400 species (Ma et al., 2009).
Globally distributed, and inhabiting both shallow
and abyssal zones below 5000 m, they occupy
different trophic levels of the food chain at various
depths in the ocean (Pérez Farfante and
Kensley 1997). This group includes most of the
prawns of high economic value that account for
one-third of the annual wild crustacean catc
Checklist of Penaeoid, Sergestid and Caridean prawns from Indian waters
No full textNon penaeid prawns constitute one of the important fishery resources contributing
to 5.8% of total marine fish production. The resource is characteristic of the northwest
and northeast coast, which accounts for 90% of the total non-penaeid prawn
production in the country. In Maharashtra and Gujarat, the non-penaeids account
for 10.8% and 12.6% of the total marine fish landings
Introduction : Handbook of Prawns
No full textThe suborder Dendrobranchiata constitute a diverse group of marine decapods with over
533 species under 68 genera ( De Grave and Fransen, 2011). Globally distributed, and inhabiting
both shallow waters and abyssal zones below 5000 m, they occupy different trophic levels of
the food chain at various water depths in the ocean (Pérez Farfante and Kensley, 1997). This
group includes most of the prawns of high economic value that account for over one-third of
the annual wild crustacean catch (FAO, 2009)

Sustainable exploitation and conservation of lobster resources in India a participatory approach
No full textLobsters are one of the most valuable and highly priced crustaceans and an important
export commodity of lndia. Though widely distributed along the entire coast, major fishery is
located on the northwest, the southwest and the southeast coasts. Although nine species of spiny
lobsters (Palinuridae) have been reported from the Indian coast (Radhakrishnan, 1993, only three
littoral and one deep sea form are commercially important. Among the six species reported from
the northwest region (Chhapgar and Deshmukh, 1971), two species, the palinurid spiny lobster
Panulirus polyphagus (Herbst) and the scyllarid Thenus orientalis (Lund) predominated the fishery
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Bibliographics for the 983 eprints in the live archives of E-LIS : trends and status report up to 7th July 2004, based on author-self-archiving metadata
No full textThe priority for ideas and philosophy related to "Network Theory" have been traced back and documented by Braun(2004),and credit goes to Karinthy(1929).The IT has empowered to realise it, as the most practical phenomena and it is no more a humour. The OAI (Open Archives Initiatives)and ACIS (Academic Contributor Information System)are progressive in the direction ,which may lead to realise the "Collective Genius" at global level. Focus of present study is on Author-Self-Archiving (A-S-A)Metadata of the 983 Eprints in the Live Archives of the E-LIS (EPrints of Library and Information Science),which were approved till 7th July 2004.The A-S-A Metadata was used for librametric analysis. Self-explanatory bibliographics are illustrated.The highlights include: Conference papers (34%); highest approval, June 2004 (28%); published archives (76%);not refereed (52%); not in public domain (60%); highest self-archiving-author (De Robbio, Antonella).The Nos. of EPrints having single JITA domain specifications were: Theoretical and general aspects of libraries and information(27); Information use and sociology of information(80);Users,literacy and reading(13);Libraries as physical collections(30);Publishing and legal issues(57);Management(13);Industry, profession and education(36);Information sources, supports, channels(113) ; Information treatment for information services, Information functions and techniques (101); Technical services libraries, archives and museums(25); Housing technologies(1); Information technology and library technology(92); and Inter-domainery (395) i.e. having specifications of two or more than two JITA classes
