Foreword
India has emerged as one of the largest producers of fish in the world with a total
productionof13.76mmt,contributing7.58%toglobalproduction.Ofthetotalfish
production,over70%comesfromtheInlandsector.TheInlandfisheriesresources
arevastintheformofrivers,canals,floodplainlakes,ponds,reservoirsandbrackish
water bodies. These resources are bestowed with wide varieties of fish species,
which are distributed based on their physiological and climatic requirements. The
fisheries sector and its spin-off activities provide livelihood opportunities to a
diverse group of rural artisans. Mapping of the resources, fish distribution pattern,
associated fishing communities, methods of fishing, income generating
opportunities, trade, etc. has led tothegeneration ofa colossal volumeof data. To
analyseandinterpretthisdata,thereisaneedtohavevariousdataanalysistools.
I am very happy that the ICAR-Central Inland Fisheries Research Institute,
Barrackpore, is publishing the book entitled Concept Building in Fisheries Data
Analysis.Thebookbuildsupaconceptualfoundationoffrequentlyusedstatistical
data analysis tools, covering both theoretical and practical approaches and its
analysis with various standard software packages. The most important part of the
book is data interpretation from the analysis output, which, in my opinion, will be
veryhelpfultothepractitionersinvolvedinfisheries.Iampleasedwiththestructural

Foreword
Fisheries professionals—most notably, students and researchers—invariably pro-
vokearesponsetostatisticaldataanalysisas‘StatisticswastheworstsubjectIliked
in my student life’. This negative attitude towards statistics consequently makes
them fumble in real-life fisheries data analysis. I do know the reason that most of
themcannotaffordtofulfil:theneedtobecompetentinstatistics.Ibelieveagood
bookcanhelptocomeoutfromthisdogma,andcompetencycanbeacquired,asfar
as basic data analysis is concerned. Unfortunately, statistics books exclusively
dealingwithfisheriesdataanalysisarerare—especiallyinIndia.
I am overwhelmed by reading this book entitled Concept Building in Fisheries
Data Analysis brought out by the group of statisticians at ICAR-Central Inland
Fisheries Research Institute, Barrackpore. The book is well structured, starting
from field data collection methods, analysis and to the interpretation of results.
Though the mathematical formulas are imperative in statistics, this book has
emphasized bringing clarity in concept, which will build a strong base in statistics
for students. Books on data analysis are undeniably plentiful, but they describe
statistics in general. But,this book isunique because of itsexclusivefisheriesdata
analysisandsubsequentinterpretationthereof.Thedatapresentationdescribedinthe
book is impressive. The authors make the readers feel that statistics is away from
mathematicalcomplexitiesandcouldbeeasytounderstand,appealingandinterest-
ing. The strongest part of the book is presentation of examples, which are taken
exclusively from field-based fisheries interventions with their post-analysis
interpretations. The exercise provided in each chapter will be highly useful for
students. Demonstration software—Excel and R—introduced in the book is the
prudent choice. Fisheries professionals feel at home in excel while R is open-
source,incurringpracticallynocost.

Effective management strategies of inland fisheries demand efficient quantitative
dataanalysisandsubsequentinterpretationofresults.Thecontributionofstatisticsis

Thusitisnecessarythatanupdatedandimprovedunderstandingofthestatistical
concepts is essential for students, researchers, planners, decision-makers and
officials associated with inland fisheries. With this in mind, a first attempt was
made in 2018, to provide training supported by a training manual to help the
researchers associated with inland fisheries. With the success and suggestions
receivedfromtheparticipantsoffirsttraining,animprovisedmanualwasprepared
during the second training programme held in 2019. Based on the feedback of the
trainees, the authors conceived the idea of publishing a book. The book design
emphasizesonbuildingthefoundationonthestatisticalconceptsothatreaderscan
easily understand and execute fundamental statistical analyses themselves. It has
boththeoreticalconceptandpracticalimplementationofthattheory.Thetheoretical
part aims at building and explaining concepts whereas the practical sessions focus
primarily on a disciplined way of data entry followed by analyses by software.
