An introduction to R programming
R language is the GNU arm of S language, which has taken the computational world by
storm in the last decade. Starting as a compendium of statistical tools, this language has
grown up into a canopy lording over a research analysis environment thereby subsuming
many hitherto complicated manoeuvres onto the realms of syntactical simplicity. As this an
exponentially expanding field of development with ever exploding information downpour,
it would be a near impossible task to frame it onto a short simple foundational discourse.
However in the subsequent sections we would try to view the potential and the extent of
practicality we would unravel the hidden features of the software through a GUI envelop
also apart from the regular console and syntax based one. To get its power more
understandable we would visualize its forays into the field of analytics using medium scale
examples from marine fisheries data
Bibliography (Part - 4) The publications by the staff of Central Marine Fisheries Research Institute 1996-2006 (A Diamond Jubilee Publication)
Central Marine Fisheries Research Institute (CMFRI) has been documenting
bibliographies on various topics. The Institute has published over a dozen such
bibliographies on various finfishes and shellfishes. Three bibliographies were
published during 1986, 1992, 1998 listing the publications of the staff of CMFRI
from 1948 to 1995. Since then, tremendous data was generated from both inhouse
and sponsored projects, leading to a good number of research publications in
national and international journals. A sincere effort has been made in the present
endeavour incorporating all the publications of the staff from 1996-2006. A total
of 2039 titles have been listed in the Bibliography Part IV including 25 titles
pertaining to period prior to 1995 which could not find a place in the earlier
bibliography

Marine fish landings in Andhra Pradesh during 2016 - An overview
Andhra Pradesh with a coastline of 974 km, and
nine coastal districts has 1.63 lakh marine fishermen
families residing in the 555 marine fishing villages
(Marine Fisheries Census 2010) who depend on
fishing either directly or through allied activities
for their livelihood. The state is cyclone prone and
during the past decade, cyclones have severely
affected the stateтАЩs fisheries sector. The marine fish
landings was 1.92 lakh tonnes (t) in the year 2016,
which was 35% less than that of the previous year.
The drastic reduction in the landings of the state
may be attributed to reduction in fishing operations
during the months of September, October and
November due to cyclone warnings. Among the
coastal districts, East Godavari contributed the
highest (33%) to total marine fish landings of the
state, followed by Visakhapatnam (22%) and
Srikakulam (11%). In spite of decline in the catch
contributions from a few landing centres like

Marine Geographic Information Systems and Their Application in Fisheries Management
GIS in marine fisheries has taken off much later than its application in
land. But the strides made in this field since 1990's has been quite significant,
as many serious mapping studies and modeling initiatives have been recorded.
With the third dimension added to the 2D spatial data, the marine GIS have all
the ingredients of making it a fertile domain for research for decades to come.
Most of the studies and products pertaining to GIS in fishery management had
been revolving around mapping of habitats, geo-referencing of catch and effort
data and modeling linking oceanographic and biogeochemical factors with living
resources. Satellite remotely sensed information like ocean colour can act as a
surrogate to fish biomass. Further remotely sensed SST, wind and other
parameters can be effectively modeled to predict fish abundance, their habitat
and related aspects. This manuscript pours into the various products and
outputs based on GIS in marine fisheries around the world and the Indian
initiatives
Enhancing the quality and utility of IndiaтАЩs Marine Fish Landing Data Collection and Processing System using spatial information
The ICAR-Central Marine Fisheries Research Institute is mandated with the monitoring and assessment of marine
fishery resources of India. The methodologies adopted for the collection and processing of fish landings data
have undergone due changes in tune with developments in the relevant scientific fields. This paper discusses
how the addition of spatial domain information explicitly to the present fish landings data collection process
would be beneficial in analysing, visualizing and extracting additional information from the fish landings datasets
Status of India's Exploited Marine Fishery Resources in 2013
The Central Marine Fisheries Research Institute
start collected and estimation of marine fish
landings for the peninsular coast of India since its
inception in 1947, based on a stratified multistage
random sampling technique. This which continues
to date, and provides knowledge-base for many
research, planning and policy initiatives in the
marine fisheries sector

Reconnoitring Annual Landings and Biochemical Profiling of Deep-Sea Driftfishes (Cubiceps: Nomeidae): A Promising Food Source
The deep-sea ecosystem is the largest habitat on the earthтАЩs
surface and is a major reservoir of global biodiversity.
тЦк The deep-sea fishery is majorly focuses on edible and commercially
important deep-sea shrimp resources.
тЦк Only a few of the deep-sea fin fishes are presently commercially
important and are mostly used for producing fish meal and
manure. The rising demand and declining conventional fishery practices have
brought deep-sea finfish into focus as a promising new protein
source. Cubiceps whiteleggii (Waite, 1894) and Cubiceps baxteri
McCulloch, 1923 included under the family Nomidae (Driftfishes) is
gaining recent importance in the commercial markets
