The increasing development of aquafeed technologies embraces a new generation of feed ingredients and additives leading to changes in the specification of diet formulations.
Current challenges and opportunities in amino acid nutrition of salmonidsInternational Aquafeed
Fishmeal is still one of the main protein sources used in commercial feeds for trout and salmon. But its availability is shrinking and its cost is increasing year by year. The sustainability of the aquaculture industry depends largely on its capability to replace fishmeal with alternative sources of protein, and to reduce the currently excessive protein levels commonly applied in the formulation of commercial diets. At the same time, feeds must be formulated to be effective in covering the nutrient requirements of specific species in order to maximise growth.
Carp is one of the main species of China's aquaculture industry, forming 13 percent of its farmed fish output. Because of their wide adaptability, carp can be farmed in an extensive variety of regions. However, in recent years their quality in China has declined. With the blind pursuit of production volumes and backward steps in breeding management technology, many problems have appeared in carp aquaculture.
Salmonid aquaculture has suffered from a number of different ailments. Infectious Salmon Anaemia, caused by the Isavirus from the orthomixoviridae family, led to a major crisis of the Atlantic salmon aquaculture industry in Chile, dramatically reducing production numbers.

Feed Management - Potential impact of nutrient substitutes in aquafeeds on fi...International Aquafeed
In most major aquafeed–based intensive aquaculture production systems there is a high reliance on nutritionally balanced complete aquafeeds. In situations where on–farm feeds are made, farmers attempt to produce a balanced feed using vitamin and mineral premixes. In all regions of the world, the increase in the cost of raw ingredients for commercially manufactured or on–farm aquafeeds resulted in an increase in aquafeed prices from 20 to 40 percent, thus forcing farmers to adopt alternative strategies to secure feeds.
South African aquaculture production, though limited in its contribution to Africa's and global production, has shown a significant increase over the past decade. Since the lifting of political and economical isolation in the early 1990’s, South Africa has experienced a rapid increase in the development of commercial aquaculture.

Aquatic animals have various feeding habits and feed intakes. For example, fish swallow feeds so they need about 40 minutes to intake feeds. However, shrimps nibble feeds so they need three to six hours to intake feeds.
It is widely recognised that fish welfare and stress are inextricably linked. When welfare is compromised and fish are under stressful conditions there are a wide range of negative effects that have been reported. These include a reduction in feed intake, growth, food conversion efficiency and flesh quality; an increase in disease susceptibility and aggression; disruption of the reproductive axis and ultimately, in extreme cases mortality.
The potential of microalgae meals in compound feeds for aquacultureInternational Aquafeed
Intensive production of mainly carnivorous fish has resulted in fish feeds containing high levels of fishmeal and fish oil, with Europe requiring around 1.9 million tonnes a year. Although this use of fishmeal was initially the recycling of waste from fishing through the use of bycatch and trimmings, due to the rapid development of aquaculture this reliance on fishmeal and fish oil is environmentally unsustainable. This has resulted in other sources of fish feed being investigated. This literature review will focus on microalgae; the composition in terms of nutritional quality, the current methods of production and associated costs along with potential future uses such as feed in aquaculture.
Fish as a source of animal protein has played an important role in the nutritional budgeting of many nations. Fish production is becoming a very important source of valuable protein food. Fishmeal is the major protein source in aquaculture feeds.

The document discusses building spiritual relationships through love in action by imitating Jesus. It says love is about serving others rather than oneself. It then outlines three ways to love in action: 1) Serve one another like Jesus washed his disciples' feet, 2) Be vulnerable with one another like Jesus shared his weaknesses, 3) Pray for one another's specific needs like Jesus prayed for Simon's faith. Readers are challenged to practically imitate Jesus' heart through serving, being vulnerable with, and praying for their spouse.
The document discusses the results of a study on the impact of COVID-19 lockdowns on air pollution. The study found that lockdowns led to significant short-term reductions in nitrogen dioxide and fine particulate matter pollution globally as human activity declined. However, the improvements were temporary and air quality returned to pre-pandemic levels as restrictions eased and activity increased again.

This document summarizes the historical and legal issues surrounding homosexual rights violations globally and in India specifically. Key points include:
- Historically, many societies accepted or condemned homosexual behavior differently. While some ancient Greek societies encouraged same-sex relationships, many religions forbid homosexual acts.
- Currently, about 70 countries criminalize homosexual behavior, with over a dozen prescribing life imprisonment or death. India's Section 377 criminalizes "carnal intercourse against the order of nature."
- There is debate around Section 377 in India. The health ministry and NGOs want it repealed to help address HIV/AIDS among homosexual communities. However, religious groups argue it would degrade morality. The document outlines arguments on both sides.
The document discusses the history and development of African art and architecture from pre-colonial times to the present. It covers major styles and artistic movements like the Mbari art of Nigeria, Benin bronzes, and Kano city walls from early history. In the 20th century, the Nsukka and Zaria Schools emerged with magazines like Okike. Artists became formally trained in the Western style. Contemporary works incorporate both African and global influences, with artists and architects collaborating across disciplines. New urban discourses are also discussed.
The Compactor Spray system automatically disperses a product called Eliminodor+ to control odors in commercial trash compactors. It uses a series of nozzles connected by tubing to spray the product into the compactor hopper. The tubing connects to a 55 gallon drum containing a pump and timer that can be adjusted based on the compactor's use. The system helps eliminate odors left behind by garbage and leaves a pleasant fragrance, needing refilling every two weeks. Eliminodor+ is a natural, biodegradable product that removes odors by stimulating microorganisms to break down odor-causing compounds.
