Abstract Niamaimandi, N., Aziz, A., Siti Khalijah, D., Che Roos, S. and Kiabi, B. 2008. Reproductive biology of the green tiger prawn (Penaeus semisulcatus) in coastal waters of Bushehr, Persian Gulf. – ICES Journal of Marine Science, 65: 1593–1599. The reproductive cycle of the green tiger prawn (Penaeus semisulcatus) was investigated in the coastal waters of Bushehr, Iran, Persian Gulf, from January 2003 to March 2004, with the aim of determining spawning seasons, durations, and locations in those waters. Bushehr waters are one of the main fishing grounds for P. semisulcatus in the Persian Gulf. Spawning peaks between December and March, but there is also some spawning in October. The minimum size at maturity was 24 mm carapace length (CL), and 50% were mature at 40 mm CL. The proportion of females that mated increased sharply above this size (40 mm), with 90% of females sexually mature at 54 mm CL. Spawning took place in a limited part of the study area, mostly offshore. Overexploiting the spawning stock could result in reduced reproductive output, limiting fishery production.

First Time

The present study identifies one species of the genus Octopus in the order: Octopoda (Cephalopoda: Mollusca), recorded forthe first time in the Iraqi coastal waters and Arabian-Persian Gulf. The study extended from January 2019 to December of thesame year. The Octopus specimens were seasonally obtained from the fishing trawlers operating in the Iraqi coastal waters inthe South of Al- Fao District, Basrah- Iraq, NW Arabian Gulf. The Octopus was identified as O. vulgaris in Iraqi coastal watersdepending on morphological features. The habitats of living specimens are briefly described. Some observations were reported on the occurrence of this species and the measurement of some environmental factors. The species was identified up to spe-cies level using standard literature. This species looks similar morphologically to the species which is already identified from the other areas around the world. The present study records significant expansion in the distribution range of this species.

Abstract This article reports on a randomized field experiment in which potential work migrants from Nepal to Malaysia and the Persian Gulf countries are provided with information on wages and mortality incidences at their intended destinations. It is found that, particularly for the group of potential migrants without prior foreign migration experience, the information changes their expectations of earnings and mortality risks abroad, which further changes their actual migration decisions. Using the exogenous variation in expectations, it is estimated that the elasticity of migration with respect to mortality rate expectation is 0.8, and the elasticity of migration with respect to earnings expectation is 1.1.

Western Victoria

The patterns of abundance of epifaunal caridean shrimps in seagrass meadows of the Hopkins River estuary, south-western Victoria, Australia were described, and environmental factors that best explained abundance patterns were sought at two scales: within and between meadows. The abundances of the three species, Macrobrachium intermedium, Paratya australiensis and Palaemon serenus, were strongly related to the position of meadows within the estuary. Patterns of abundance between meadows were likely to be determined by distribution of larval recruits, and extent of post- larval migration, both between meadows and to and from stocks outside the estuary (the river upstream for Paratya, and adjacent coastal waters for Macrobrachium and Palaemon). Variation in caridean abundances over 1 year was related to temperature and salinity. Patterns of recruitment and migration could in part be explained by physiological responses to physico-chemical changes. However, it is hypothesized that competitive exclusion from preferred deeper parts of meadows is a trigger for migration of Paratya from the estuary. Although caridean densities within some meadows were at times correlated with seagrass biomass, patterns of seagrass abundance did not explain between-meadow patterns of caridean abundance well.
