Hundreds of millions people on the planet are affected by malnourishment. This contributes to vulnerability large swaths population worldwide. Children under five years old and adolescent girls especially disproportionately vulnerable diseases even death in less developed countries. Today, providing a substantial share global protein intake, as well fatty acids micronutrients, fisheries contribute food security. As fish stocks upper sea levels increasingly over-exploited, there is surge discussion potential contributions deep-sea for nutrition Some mesopelagic fishes show important nutrients. Another way supplying security might be using feed. However, fishing zone could lead severe ecological repercussions, because impact biological carbon pump uncertain. paper highlights juxtaposes different perspectives regarding exploitation pathways riches deep seas, reviews best practice model projects that deal with uncertainties related fishery management zone. The review concludes due essential role complex interaction patterns between pelagic species, must based comprehensive data rigorous analyses. In face current uncertainty respective mechanisms, authors endorse an international moratorium and/or rather small-scale biomass.

Resource harvesting in inland fisheries during a single fishing season is mathematically modeled based on an extended mean field game played by many anglers. The rate of each angler depends that the others through interaction. Each wants to maximize utility, while resource overexploitation effectively penalized incentives for conservation. Anglers' activities are represented controlled jump processes arising as unique nonlinearity game. Solving reduces resolution forward-backward system containing Hamilton–Jacobi–Bellman and Fokker–Planck equations coupled rate. average total visiting time per obtained byproduct from system, which used investigate scheme license fee fisheries. A finite difference method proposed numerically compute Picard iteration. convergence numerical solution equation analyzed discontinuous viscosity solutions. Finally, we specify fish population dynamics data major fishery Plecoglossus altivelis 2023 Japan. Computational examples presented analyze our mathematical model.

In most situations where entities interact by sharing limited resources, controlling population density is crucial for maintaining ecosystem sustainability. Mathematical models have been widely used to explain systems arising from the interaction between populations and nature, particularly regarding resource utilization. The objective of our work develop a mathematical model that incorporates effort renewal harvesting populations, represented through system nonlinear differential equations. analysis developed in study involved demonstrating well posed, admitting unique solution within defined domain, identifying equilibrium points their stability system. Numerical simulations were conducted understand dynamics utilization, population. numerical simulation global was also examined. Sensitivity parameters performed, revealing viability depends on renewal. Specifically, identified three types parameter variations: first category influences natural resources form sinusoidal periodic changes, which may be continuous or discontinuous. second does not influence dynamics. third includes affect short term but long term.

Ethnic areas are special in terms of their geographic type, population size, production mode, etc. Scientific assessment rural residents’ livelihood resilience and exploration its influencing factors significant for tapping the potential promoting sustainable development. This research takes villages western Sichuan ethnic area as study and, based on framework analysis resilience, constructs an evaluation index system explores affecting evolution using OLS parameter estimation method. The results found that: (1) Annual per capita income diversification key farm households have improved under revitalization strategy. (2) Skill training opportunities, loan living conditions, non-agricultural work experience, traffic accessibility had most impact were dominant forces enhancing resilience. (3) There was a divergence among different types residents, those with low altitude, dependency ratio, strong labor endowment, high literacy higher resilience; furthermore, mean value tourism-led residents than that non-tourism-led strategies.

This study investigates the use of untapped mesopelagic species as a source long-chain polyunsaturated omega-3 fatty acids (LC n-3 PUFAs) to meet growing demand. The challenges faced by commercial fishing vessels, such varying catch rates and distribution affecting lipid levels, are addressed. Marine oils were produced post-catch using thermal separation enzymatic hydrolysis during four cruises, screening approximately 20,000 kg mixed species. Maurolicus muelleri Benthosema glaciale dominant in catch, while krill was primary bycatch. composition varied, with B. having higher prevalence wax esters, triacylglycerols phospholipids more predominant other LC PUFAs ranged from 19% 44% lipids, an average EPA + DHA content 202 mg/g oil. Both processing methods achieved oil recoveries over 90%. Estimates indicate that biomass Northeast Atlantic could supply annual recommended levels 1.5 million people, promoting healthy heart brain functions. These findings offer valuable insights for considering potential dietary marine laying groundwork further research innovation obtaining compounds
