Description of a new goatfish species, Upeneus randalli n. sp. (Mullidae), from the Persian Gulf, with remarks and identification keys for the genus Upeneus
(Journal article; Peer reviewed, 2011-09)The number of species of the goatfish genus Upeneus from the western Indian Ocean has increased considerably due to recent taxonomic efforts. Here we describe a new species, Upeneus randalli n. sp., based on body and fin ... -
Does size matter? A bioeconomic perspective on optimal harvesting when price is size-dependent
(Journal article; Peer reviewed, 2011-09-09)Body size is a key parameter influencing demographic characteristics of fish populations as well as market value of landed catch. Yet in bioeconomic modelling, body size is often an overlooked biological and economic ... -
Guidelines towards an integrated ocean observation system for ecosystems and biogeochemical cycles
(Journal article; Peer reviewed, 2009)The observation of biogeochemical cycles and ecosystems has traditionally been based on ship-based platforms. The obvious consequence is that the measured properties have been dramatically undersampled. Recent technological ... -
The sampling volume of trawl and acoustics: estimating availability probabilities from observations of tracked individual fish
(Journal article; Peer reviewed, 2009-03-10)The effective sampling volume of trawl and acoustics is an important parameter in fish abundance estimation surveys. This paper presents a method to compute the probability of a fish being available to the bottom trawl and ... -

Toward a Global Ocean Ecosystem Mid-trophic Automatic Acoustic Sampler (MAAS)
(Journal article; Peer reviewed, 2009-05-26)Despite their huge biomass and pivotal role, the mid-trophic levels of marine ecosystems are not generally subject to systematic monitoring. Data from such monitoring is crucial for parameterizing, validating, and constraining ...
