Although contract reparations have been extensively studied in the context of deontic logics, there is not much literature using reparations in automatabased deontic approaches. Contract automata is a recent approach to modelling the notion of contract-based interaction between different parties using synchronous composition. However, it lacks the notion of reparations for contract violations. ...
non-commercial fish species of shrimp trawls were studied monthly from october 2005 to september 2006 in mahshahr creeks (darvish, doragh, bihad, ghazaleh, ghanam, zangi and patil). the trawl nets had a cod-end mesh size of 24mm. total catch was 6431 individuals weighing 55.5kg, and included 14 species of non-commercial fish species belonging to 14 families. the caught shrimp species were from ...
Tuna purse seine fishery is a commercial and industrial fishery in the Iranian waters of Oman Sea. An observer programme was conducted to identify the by-catch composition of the tuna purse seine fishery in the Iranian waters of the Oman Sea. Investigations were carried out on board of purse seiner vessel “named Parsian Shila” between September and October 2015. The by-catch was composed of 17 ...
This paper is a comprehensive study of the shrimp trawl by- catch from Bushehr coastal waters (N. Persian Gulf). Sampling operation was carried out in two shrimp fishing seasons using the (Saber and Jahanara) commercial trawlers Generally, 87.5% of the total catch was by-catch and 12.5% was target species (shrimp). The catch composition included: 114 species from 45 teleostei families, 13 speci...
The present study aims to recognize dhow prawn trawl by-catch from Hormuzgan coastal waters (Northeast Persian Gulf). Sampling was carried out of 36 hauls by using traditionally wooden dhow among prawn fishing season in 2011. The catch composition consisted of 31.66% target species prawns, mainly banana prawn (Penaeus merguiensis) and 68.34% by-catch. The total by-catch was 4,622.67kg com...
the catch composition of the bottom trawl fishery along the coasts of karataş was evaluated in the 2002-2003 fishing season. a total of 110 species were registered, the fishes showed the highest diversity (90 species) followed by 15 crustaceans species and 5 species of cephalopods. the highest catch per unit effort (cpue) value (66.8 kg h -1 ) was recorded in september when the fishing season w...
this study evaluates changes in species composition, catch, and cpue of three species of kilkas in the caspian sea from 1961 to 2009. the effects of fluctuations in sea level rise and fall on the catch of kilka as well as the impacts of a recent invasion by mnemiopsis leidyi (ctenophora) were assessed in terms of species composition and cpue of kilkas in the iranian coastal region of the caspia...
The aim of the present study was to evaluate the illegal Silver pomfret catch by fixed gill-nets in Hormozgan inshore waters (Qeshm Island). Sampling was performed in Bandar Laft estuaries through three fishing boats between April to July 2015. The fishing gears were the nylon mono-filament fixed gill-net with 6.5 cm mesh size (bar), 200 m length and 8-10 m height. The non-parametric bootstrap ...
Yellowfin Tuna (Thunnus albacares) is one of the most important commercial and neritic fish species which has known because of ecological importance and wide distribution around the world. The aim of this study was to determine relative index of abundance for Yellowfin Tuna from 2007 to 2016, also we evaluated effect of some explanatory variables (year, month, vessel tonnage and net height) of ...
