This paper reports on the results of a trawls survey in 2011 to assess the amount of biomass and Catch Per Unit of Area (CPUA) as well as to determine the distribution pattern of Synodontidae family of demersal fishes (with emphasize on great lizardfish, Saurida tumbil) as one of the most important and commercial fish species in the northwest of the Persian Gulf.  Samples were collected fr...

The small-scale lobster fisheries of Madagascar's impoverished southeast coast account for the majority of national catch and export, making a significant contribution to the regional economy. Data suggests catches have declined, likely due to over-exploitation. In response, the community of Sainte Luce has established a locally managed marine area (LMMA) to manage their lobster fishery, includ...

This study models a joint pricing, inventory, and preservation decision-making problem for deteriorating items subject to stochastic demand and promotional effort. The generalized price-dependent stochastic demand, time proportional deterioration, and partial backlogging rates are used to model the inventory system. The objective is to find the optimal pricing, replenishment, and preservation t...

Context Contrary to other ocean basins, Indian Ocean catches have increased consistently since 1950, although reported data are known be incomplete. Fish is a crucial food source in the Ocean; however, ineffective management often empowers over-exploitation. Aims We synthesised and reviewed reconstructed catch effort by fishing sector country at ocean-basin scale. Methods aggregated unreported ...

The purpose of this study was to analyze the catch per fishing effort (CPUE) Red Snapper (Lutjanus sp) resources and comparison catches based on gear used. results showed that in waters Lewalu Village period January – December 2021 fluctuated tended decrease with an average CPUE value 11,499 kg/trip/year. from Fishing Line Rawai Units shows there is a difference catch.

in this paper, we analyze the dynamics of income gap between 138 countries with usa by using time series model of convergence hypothesis and various panel unit root tests over period 1950-2008. all panel unit root tests don’t reject the null hypothesis of unit root. univariate unit root tests results show that gdp per capita of south korea, switzerland, austria, lesoto and hungry catch up with ...

The trawl fishery of the Mediterranean coast of Israel was analyzed vis á vis catch and fishing effort for the years 1949-2010. The Maximum Sustainable Yield (MSY) was calculated using the Fox surplus-yield model and was found to be 1,413 ton per annum using 1,415 units of effort (fishing days X engine power divided by 1000). Only during nine years (1997-2005) did fishing effort exceed the valu...

Abundance of the Ommastrephes bartramii winter-spring cohort fluctuated greatly from 1995 to 2004. To understand how abundance was influenced by sea surface conditions, we examined the variations in the proportion of thermal habitats with favourable sea surface temperature (SST). The SST data of both the spawning and feeding grounds were used to calculate the monthly proportion of favourable-SS...

The Torres Strait tropical rock lobster Panulirus ornatus (TRL) fishery is of immense social, cultural and economic importance to the region’s Indigenous fishers from both Australia Papua New Guinea (PNG). During 2020, COVID-19 pandemic indirectly impacted this as well a number other fisheries reliant on international export markets. TRL managed using an empirical (data-based) Harvest Control R...
