Mycobacterium stephanolepidis is a rapid-growing nonpigmented species isolated from marine teleost fish (Stephanolepis cirrhifer) and is closely related to Mycobacterium chelonae Here, we report the complete sequence of its genome, comprising a 4.9-Mb chromosome. The sequence represents essential data for future phylogenetic and comparative genome studies of this fish pathogen.

While a rich variety of self-propelled particle models propose to explain the collective motion of fish and other animals, rigorous statistical comparison between models and data remains a challenge. Plausible models should be flexible enough to capture changes in the collective behaviour of animal groups at their different developmental stages and group sizes. Here, we analyse the statistical ...

Purse seining for tropical tuna is one of the most technologically advanced fisheries in the world. The purpose of this study was to apply Local Ecological Knowledge (LEK) to assist in the planning of future in situ studies of fish behaviour around Drifting Fish Aggregating Devices (DFADs) by prioritizing research topics, thereby reducing the number of potential hypotheses to explore. Interview...

The potential attraction of fish to thin layers of zooplankton and the role of predation by fish in the formation and persistence of these layers were assessed using 3-dimensional sonar observations. Zooplankton were found in intense layers with vertical scales of 0.2 to 4.6 m with a mode of 2.2 m. These thin zooplankton layers had complex 3-dimensional structure with significant, though gradua...

Ordinal and comparative rating measures of mosquito attraction and mosquito bite frequency and symptoms were administered in a self-report questionnaire format to a sample of 197 monozygotic and 326 dizygotic Australian adolescent twin pairs at age 12 between 1992 and 1999, in order to investigate the environmental and possibly genetic determinants of variation between individuals. Repeat measu...

There has been much interest in CpG islands (CGIs), clusters of CpG dinucleotides in GC-rich regions, because they are considered gene markers and involved in gene regulation. To date, there has been no genome-wide analysis of CGIs in the fish genome. We first evaluated the performance of three popular CGI identification algorithms in four fish genomes (tetraodon, stickleback, medaka, and zebra...

Predation is thought to shape the macroscopic properties of animal groups, making moving groups more cohesive and coordinated. Precisely how predation has shaped individuals' fine-scale social interactions in natural populations, however, is unknown. Using high-resolution tracking data of shoaling fish (Poecilia reticulata) from populations differing in natural predation pressure, we show how p...

This work compares the effect of the climate and some different protein diets on the activity of flesh and blow fly populations in one of the biggest mountains of Sarah region, south-west Kingdom of Saudi Arabia. Trapping of adult flies revealed the presence of three populations, namely, Engelisca adhamae (Lehrer & AbouZied, 2008) and Liosarcophaga babiyari (Lehrer, 1995), in addition to a sing...

Brycon hilarii is a migratory fish widely distributed throughout the Paraguay River Basin. It is appreciated in sport fishing and for its superior meat quality. It is also the main species for tourist attraction in the Bonito region (State of Mato Grosso do Sul, Brazil). Considering the lack of information on the genetic structure of the fish of this species, the aim of the present study was to...

Indonesia is a maritime country that has sea area of ​​5.8 million km², with enormous potential for marine products. The fisheries sector one the things supports third largest Indonesian economy GDP (Gross Domestic Product) Rp 1.900 billion. There are many fishery ports in commonly referred to as Fish Landing Base. In North Sumatra itself, there 23 Base, and areas include it RTRW (Regional Spat...
