Large white, Grade A chicken eggs, sold in a carton of a dozen. Includes organic, non-organic, cage free, free range, and traditional."

In 2024, the retail price for a dozen eggs in the United States was **** U.S. dollars. Egg prices in the United States peaked in this year. Previously, the highest average price was in 2015, when a dozen eggs cost **** U.S. dollars on average. U.S. egg production The United States was one of the leading producers of eggs in the world in 2021, ranking fourth behind China, India, and Indonesia. In that year, approximately ***** billion eggs were produced in the United States. There are two main categories that farm chickens fall into: broiler chickens and laying hens. The first are raised for meat and the second are raised for laying eggs. The U.S. state with the most laying hens is Iowa, with about **** million in 2022. Some of the other top egg-producing states include Ohio, Indiana, and Pennsylvania. Egg retail in the United States Perhaps because eggs are uniform in taste and appearance, and most consumers cannot tell one brand of chicken egg apart from another, private label eggs have the highest sales among fresh egg brands in the United States. Eggland’s Best is the leading name brand of fresh eggs in the United States, with sales of ****** million U.S. dollars in 2023. The amount that U.S. consumer units spend on eggs varies from region to region. In 2021, consumers in the Western United States spent an average of about *** U.S. dollars on eggs over the course of the year. The Midwestern United States had the lowest average expenditure on eggs in that year.

There is increasing global awareness of the need for sustainable aquaculture. Aquaculture represents a potential mechanism for supplementing wild fish harvests, either through stocking of cultured animals or farming to market size. In the first case, stocked animals would be available to sport and commercial fishermen. In the latter, consumer demand would be met directly with a farmed product, reducing pressure on wild stocks. By the year 2030, the global population is projected to reach 8.2 billion, with an expected demand for seafood of 150 million metric tons (mmt), 54 mmt of which the Food and Agriculture Organization (www.fao.org) estimates that aquaculture must contribute. Meanwhile in the U.S., an astounding 86% of the seafood consumed is imported ($9 billion annually), which makes seafood second only to oil as the largest natural resource contributor to our national trade deficit. There remains a great need for U.S. aquaculture production to fill the seafood void. Commercial-scale production of marine finfish in the U.S. is limited to a handful of species, however, including red drum, Pacific threadfin, cobia, cod, and flounder (excluding the anadromous Atlantic salmon), and production is often inconsistent. On the U.S. West Coast, many native marine species represent good potential candidates for aquaculture. Most of these, such as California sheephead, California halibut, cabezon, lingcod, white seabass, and rockfishes, are fully or over-exploited by capture fisheries. Other high-value species like California yellowtail and yellowfin tuna are transitory, with apparently healthy populations, but based on success elsewhere in the world, are believed to offer excellent potential for commercial aquaculture development in the U.S. A major step in the creation of a viable and profitable marine aquaculture industry lies in developing reliable fingerling production, and central to this is understanding the variables that determine egg and larval quality. The lack of knowledge in what optimizes egg and larval quality is an important limiting factor in developing culture techniques for any species (Kjorsvik et al. 1990; Bromage 1995). Inconsistent or poor egg quality significantly affects the production and viability of larval and juvenile fish. In the absence of high-quality eggs, it is not possible to optimize husbandry practices because larval performance is substandard under typical culture conditions, such as high stocking densities, aggressive weaning regimes, and grading or other handling procedures. Unfortunately, identifying simple indicators of egg quality has been difficult as no individual metric is universally applicable within and among species. This proposal seeks to identify easy-to-use indictors, as well as determine pre- and post-spawning factors that affect egg quality, in up to three very different ecologically and economically valuable marine fish species native to the U.S. West Coast: a highly-pelagic finfish, the California yellowtail (Seriola lalandi; CYT); a deep-sea whitefish, the sablefish (Anoplopoma fimbria; SF); and/or a semi-resident benthic flatfish species, the California halibut (Paralichthys californicus; CH). All three species are multiple batch spawners, producing large numbers of eggs several times over the course of a spawning season. Defining the differences between high and low quality eggs and documenting correlations between quality and different conditions (e.g. broodstock diet, age, domestication status, spawning methods, or progression through the spawning season) will directly impact the success of culturing species like these. If inferior batches of eggs can be identified early on, culturists would have a valuable tool, which would significantly advance mariculture development along the U.S. West Coast and elsewhere by leading toward consistent fingerling production of species with great potential for culture.

The U.S. state with the highest number of laying hens in 2024 was Iowa with approximately 43.7 million head of chicken. The United States is also the fourth leading producer of eggs worldwide. Egg industry The global production volume of eggs reached about 86.4 million metric tons in 2021, up from about 55 million metric tons in 2000. The vast majority of the world’s chicken eggs are produced in China. In 2021, some 586 billion eggs were laid in China, about five times more than the United States. The total value of eggs produced in the United States peaked in 2015, but has since decreased. Egg retail in the United States In the United States eggs are a popular breakfast food as well as an ingredient in many recipes. Since chicken eggs seem to be more or less homogenous across different brands, private label eggs are the leading fresh egg brand in the United States in terms of dollar sales. In 2022, the best selling name brand of fresh eggs was Eggland’s Best, followed by Vital Farms and Pete & Gerry’s.

Theory describing evolution of offspring size often assumes that the production cost per unit volume is the same for small and large offspring. However, this may not be true if indirect costs of reproduction (e.g., material and energetic costs of supporting offspring development) scale disproportionately with offspring size. Here we show how direct and indirect costs of reproduction can be explicitly modeled within the Smith-Fretwell framework and how observations of size-number relationships can thus be used to evaluate indirect costs. We applied this analysis to measures of egg volume and fecundity for over 300 individuals of a coastal fish species and found that the tradeoff was much stronger than the expected inverse (fecundity scaled with volume-1.843). Larger offspring were thus more expensive to produce. For our study species, an important indirect cost was that larger eggs were accompanied by disproportionately more ovarian fluid. Calorimetry and removal experiments were used to..., , , # Data from: indirect costs of reproduction and the tradeoff between offspring size and number: a framework illustrated by fitness costs and benefits of ovarian fluid

The sweet potato whitefly (Bemisia tabaci) is a damaging insect pest that feeds on hundreds of crop plants. Oviposition rate is a useful metric to screen plants for whitefly resistance. Whitefly eggs are small and translucent, and can therefore be hard to count on the leaves of some crops. In this research, we tested a selective egg staining process on five crop species to determine if egg staining can improve the visualization and quantification of whitefly eggs. By comparing the egg counts before and after staining using two-sample Wilcoxon signed-rank tests (a non-parametric test for paired analyses). Two individuals counted the eggs, and for both these counters we found a significant increase in the number of visible eggs after staining on melon, tomato, and cowpea. This method could be applied to improve phenotyping for whitefly resistance in plant breeding applications.

The location and abundance of fish eggs provide information concerning the timing and location of spawning activities and can provide fishery-independent estimates of spawning biomass. However, the full value of egg and larval surveys is severely restricted because many species’ eggs and larvae are morphologically similar, making species-level identification difficult. Recent efforts have shown that nearly all species of fish may be identified by mitochondrial DNA (mtDNA) sequences (e.g., via “DNA barcoding”). By taking advantage of a DNA barcode database, we have developed oligonucleotide probes for 23 marine fish species that produce pelagic eggs commonly found in California waters. Probes were coupled to fluorescent microspheres to create a suspension bead array. Biotin-labeled primers were used to amplify the mitochondrial cytochrome oxidase subunit I (COI) and 16S ribosomal rRNA genes from individual fish eggs. The amplicons were then hybridized to the bead array and after addition of a reporter fluorophore, samples were analyzed by flow cytometry with Luminex 100 instrumentation. Probes specifically targeted eggs that are abundant and/or from morphologically indistinguishable species pairs. Results showed the 33 different probes designed for this study accurately identified all samples when PCR was successful. Suspension bead arrays have a number of benefits over other methods of molecular identification; these arrays permit high multiplexing, simple addition of new probes, high throughput, and lower cost than DNA sequencing. The increasing availability of DNA barcode data for numerous fish faunas worldwide suggests bead arrays could be developed and widely used for fish egg, larval and tissue identifications.

Egg production rates were determined on CCE process cruises for three species of copepod: Calanus pacificus, Metridia pacifica, and Eucalanus californicus. Copepods were collected by bongo net and adult females were promptly sorted into individual Petri dishes. Dishes were checked for eggs every 12 hours for a period of 24 hours for C. pacificus and M. pacifica, and 72 hours for E. californicus. Egg production rates are expressed as eggs per female per day. Eggs were incubated for an additional 36 hours for assessment of hatching success. The prosome length of the adult females was measured by ocular micrometer. Egg production rates can be used as a metric of secondary production.
