1. Aquaculture involves cultivating aquatic organisms under controlled conditions for commercial purposes. It can help meet protein needs, create jobs, and utilize water and land resources.
2. There are three main culture systems - open, semi-closed, and closed. Open systems use natural environments like cages and ponds. Semi-closed systems use ponds and raceways supplied by natural water sources. Closed systems fully control the environment in tanks.
3. India has many suitable inland water bodies for aquaculture, including ponds, tanks, reservoirs, floodplains, and swamps. Pond aquaculture is a major industry, with productivity increasing from 600-800 kg/ha/yr to

Culture fishery
Fish culture, also called pisciculture, involves the controlled rearing and breeding of fish in confined water bodies like ponds, reservoirs, and paddy fields. Fish culture can be classified based on the type of water body, management approach, species stocked, type of enclosure, and climatic conditions. The main classifications are extensive, semi-intensive, and intensive systems; pond, cage, and pen cultures; monoculture and polyculture; and warm and cold water cultures. Pisciculture plays an important role in augmenting food production and generating employment.
Aquaponics Growing Fish and Plants Together
This document provides an overview of aquaponics, which is a sustainable food production system that integrates aquaculture (raising fish) and hydroponics (growing plants without soil). In aquaponics, the waste produced by fish provides nutrients for plants to grow. The bacteria in biofilters convert the fish waste into plant-available nutrients, and the plants help filter the water for the fish. Aquaponics uses less water than traditional agriculture and fish or plant production alone. It allows for local food production with minimal environmental impact.
fresh water prawn.pptx
This document discusses freshwater prawn farming. It begins by introducing freshwater prawn species commonly farmed, including Macrobrachium rosenbergii. It then covers the life cycle of M. rosenbergii from eggs to adult. The document outlines best practices for freshwater prawn farming, including pond construction and management, water quality parameters, feeding, stocking densities and harvesting techniques. The goal of freshwater prawn farming is to reproduce and raise prawns in captivity in earthen ponds, with a harvest time of 90-120 days.
AFA-Chapter 7-Fish culture-Lesson 1 -DITAN-SAMPAGA.pdf
Fish culture involves raising fish in captivity and managing their environment. It has several purposes like enhancing food supply and income. There are different methods of fish culture based on factors like the level of investment, water conditions, and fish species. Common methods include pond, pen, cage, and tank systems. Fish culture provides food and economic benefits while supporting sustainable use of resources.
Water quality management in tilapia intensive farming
Tilapia farming requires maintaining good water quality to promote fish growth. Several factors influence water quality as fish stocking densities increase, including feed input and the water's assimilative capacity. Poor water quality can harm fish health, degrade product quality, and endanger human health. Tilapia are highly tolerant freshwater fish that generally thrive in temperatures between 22-29°C, pH of 7-9, and dissolved oxygen above 3mg/L. Proper management of environmental factors is needed for profitable tilapia production.
Mud crab
The document provides information about the mud crab (Scylla serrata), including its classification, distribution, ecology, and methods for farming and hatchery management. It notes that mud crabs are found naturally in the Indo-Pacific region and are an economically important species. Mud crab farming can be done using grow-out systems, where young crabs are raised for 5-6 months until market size, or fattening systems, where soft-shelled crabs are raised for a shorter period. Hatchery management involves broodstock selection and care, spawning and larval rearing techniques, and achieving survival rates as high as 18.1% compared to the world average of 3-3.5
Aquaponics Growing Fish And Plants Together
This document provides an overview of aquaponics, which is a sustainable food production system that integrates aquaculture and hydroponics. It works by circulating the water from fish tanks to grow plants. The fish waste is broken down by beneficial bacteria into nitrates, which are absorbed by the plants as nutrients. This cleanses the water, which is then recirculated back to the fish tanks. Aquaponics uses less water than traditional agriculture and the waste from one component serves as food for the other, making it a closed-loop system.

Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.

Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

Anti-Universe And Emergent Gravity and the Dark Universe
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

. The transient was identified in deep James Webb Space Telescope (JWST)/NIRCam imaging from the JWST Advanced Deep Extragalactic Survey (JADES) program. Photometric and spectroscopic followup with NIRCam and NIRSpec, respectively, confirm the redshift and yield UV-NIR light-curve, NIR color, and spectroscopic information all consistent with a Type Ia classification. Despite its classification as a likely SN Ia, SN 2023adsy is both fairly red (

Ca-rich SNe Ia, SN 2023adsy is standardizable and gives no indication that SN Ia standardized luminosities change significantly with redshift. A larger sample of distant SNe Ia is required to determine if SN Ia population characteristics at high-

counterparts, and to confirm that standardized luminosities nevertheless remain constant with redshift.

TOPIC OF DISCUSSION: CENTRIFUGATION SLIDESHARE.pptx
Centrifugation is a powerful technique used in laboratories to separate components of a heterogeneous mixture based on their density. This process utilizes centrifugal force to rapidly spin samples, causing denser particles to migrate outward more quickly than lighter ones. As a result, distinct layers form within the sample tube, allowing for easy isolation and purification of target substances.
