Inland fisheries are commercial fishing operations that take place in freshwater, providing high-quality protein, vital nutrients, and minerals. India is the third-largest fish producer world, producing 7.96 per cent of world's fish. Gujarat produces most marine India, accounting for 18.80 total production 1.51 inland production. has potential to develop fishery sector due its massive resources...

When trade-offs involving predation and mortality are perturbed by human activities, behaviour and life histories are expected to change, with consequences for natural mortality rates. We present a general life history model for fish in which three common relationships link natural mortality to life history traits and behaviour. First, survival increases with body size. Second, survival decline...

Families or family businesses own nearly all of the private redwood forestland in California. Family forest owners have practiced both subdivision and silviculture for decades but the dominant theme for most family owners is environmental stewardship. Parcel size is more important than expressed values as a predictor of resource management activities. All landowners with more than 50 acres unde...

Household harvesting of wild fish and game contributes to food security in indigenous communities across the Arctic, some regions plays an important role cultural identity peoples. The degree which state regulates restricts distribution country foods varies widely, however, this intervention local economies can affect livelihood opportunities. paper hypothesizes that where policy has contribute...

Commercial harvesting is recognized to induce adaptive responses of life-history traits in fish populations, in particular by shifting the age and size at maturation through directional selection. In addition to such evolution of a target stock, the corresponding fishery itself may adapt, in terms of fishing policy, technological progress, fleet dynamics, and adaptive harvest. The aim of this s...

As fish is a perishable food item, multiple storage approaches need be considered to extend its shelf-life, safety, and quality. Despite advancements in modern frozen techniques, chilling freezing remain the most frequently employed preservation practices onboard. The purpose of this review outline ways increasing shelf-life fresh by assessing different conventional conditions. Although there a...

In this paper, using sub-supersolution argument, we prove an existence result on positive solution for an ecological model under certain conditions. It also describes the dynamics of the fish population with natural predation and constant yield harvesting. The assumptions are that the ecosystem is spatially homogeneous and the herbivore density is a constant which are valid assumptions for mana...

Here, I explore the system-level consequences of learning and adaptation among fish and fishers. The fundamental idea is that the cost of acquiring the knowledge needed to resolve uncertainty is the principal driver of social and spatial organization. This cost limits agents’ actions and leads them to prefer relatively persistent associations with familiar agents and places. When all agents act...

Black pomfret Parastromateus niger is a commercially important fishery resource in the Persian Gulf but harvesting its stocks lacks genetic identification of populations. AFLP technique was applied to analyze genetic diversity and population structure of 32 fish from coastal waters of Bandar Abbas, Bushehr and Abadan with 7 EcoRI/MseI primer pair combinations. In total, 381 bands were produced ...
