Data mining and extrapolation of drug residues, pharmacokinetic and toxicological data in aquatic species

Evaluation of drug residues and computation of pharmacokinetic parameters in different aquatic species

Development of searchable Database of drug residue Pharmacokinetics Data in aquatic species (Phish-Pharm) PhD candidate, Animal Breeding & Genomics Center, Wageningen University, Netherlands 2002- 2006

Investigated the natural mating system and reproductive success of tilapia (Oreochromis niloticus); estimated effective population size and rate of inbreeding under semi-natural conditions

Investigated effect of inbreeding on reproductive success, survival, body weight and fluctuating asymmetry

Outlined a breeding plan for small-scale fish farmers that maximized genetic gain without accumulating higher levels of inbreeding in farmed tilapia

Proposed a scheme of population subdivision and exchange of breeders to keep inbreeding at an acceptable level

Conducted several experiments on size-dependent competition and cannibalism in tilapia reared in recirculation aquaculture systems

Research Fellow, the WorldFish Center, Regional Office, Abbassa, Egypt 2003- 2005

Conducted spawning experiments and collected genetic and meristic data

Parentage analysis to investigate mating systems and reproductive success of fish in breeding hapas

Produced offspring with five different levels of inbreeding and investigated the effect of inbreeding on different traits in Nile tilapia (survival, body weight, reproductive success and fluctuating asymmetry)

Investigated size-dependent cannibalism in juvenile Nile tilapia and proposed a predator to prey ratio to reduce fry losses due to cannibalism
