(2012)Type: Journal ArticleLarge scale cage culture of mullet is new practice in Egypt and have not economically evaluated. The aims of this study are: to assess the economic potential of the actual practices of private mullet cage operations in ... -
Estimates of average energy requirements in Bangladesh: Adult Male Equivalent values for use in analyzing household consumption and expenditure surveys
(2017)Type: Journal ArticleThis dataset contains Adult Male Equivalent (AME) values for use in Bangladesh. These were constructed using prescriptive nutritional constructs adapted to the actual growth and weight pattern seen in Bangladesh. This ... -
Estimates of phenotypic and genetic parameters for carcass traits in Nile Tilapia selected for fast growth in low-input conditions
(2005)Type: OtherNile tilapia is sold as either un-gutted or gutted whole carcasses, or as depending on geographical location. In whichever state the is sold, meat yield is an important consideration. Although carcass traits are of economic ... -
Estimates of strain additive and non-additive genetic effects for growth traits in a diallel cross of three strains of giant freshwater prawn (Macrobrachium rosenbergii) in Vietnam
(2010)Type: Journal ArticleAdditive genetic, heterotic and strain reciprocal effects were estimated using a diallel cross of two local wild strains of the giant freshwater prawn (Macrobrachium rosenbergii) in Vietnam (Dong Nai and Mekong) and a third ... -

(1995)Type: Journal ArticleThis contribution is a summary of the results of the study conducted by the University of the Philippines in the Visayas team from November 1990 to June 1991. The purpose of this research is to estimate demand and output ... -
Estimating natural mortality of Kuwait's Penaeus semisulcatus using a new tag-recapture data analysis method
(1990)Type: Journal ArticleA novel method was used to estimate natural mortality (M) of Kuwaiti Penaeus semisulcatus using tagging data. The new M estimator is based on two tagging experiments with similar products of initial survival after tagging ... -
Estimating the food consumption of fishes: one step in linking a species with its ecosystem
(1990)Type: Journal ArticleDetails are given of a new software package MAXIMS which may be used to estimate the daily food consumption of fish. The software estimates the feeding times, the rates of ingestion and evacuation and related parameters. ... -
Estimating the girth of fish by applying an elliptic model
(1994)Type: Journal ArticleA new method for estimating the maximum girth of roundfish is proposed as illustrated; this is based on an elliptic approximation of the cross sections of the fish body. Results derived from a small sample horse mackerel, ... -
Estimating the maximum sustainable yield of bonito (Sarda chiliensis, Scombridae) of northern Chile from monthly catch data
(1992)Type: Journal ArticleMonthly catch data of bonito Sarda chiliensis from northern Chile, from 1976 to 1989, were used to obtain a series of estimates of the "Z-G" parameter (i.e., total mortality minus the growth coefficient in weight). This ... -
Estimation and comparison of fish growth parameters from pond experiments: a spreadsheet solution
(1988)Type: ManualA method is presented to estimate and compare the growth of fish in pond experiments using a Gulland/Holt plot. The method is implemented as a LOTUS 1-2-3 "spreadsheet" allowing easy data editing and analysis. An example ... -
