This study describes results on sexual maturation and characteristics of natural spawned eggs to develop a method for the production of stable, healthy fertilized eggs from captive-reared yellowtail kingfish, Seriola lalandi. A total of 59 yellowtail kingfish were captured off the coast of Jeju Island, after which the broodstock was cultured in indoor culture tank (100 m(3)) until they were 6.1...

Horseshoe crab (HSC) amebocyte cells degranulate to form a gel clot when in contact with endotoxins. This phenomenon is the basis of both horseshoe immune system and detection endotoxin biologicals. captive rearing has been suggested as promising method for continuous cell harvesting. Hence, we aimed investigate quality Tachypleus gigas pre post bleeding under captivity. Wild crabs (5 months ca...

The effects of stocking density on fish welfare are complex and involve many interacting parameters. This relationship between welfare, influencing factors make it challenging to define a specific optimal (“golden”) density. Indeed, previously published recommendations for different species aquaculture interest incredibly variable even at the same life stage, can also vary widely within rearing...

This paper exploits a unique ongoing experiment to analyze the effects of early rearing conditions on physical and mental health in a sample of rhesus monkeys (Macaca mulatta). We analyze the health records of 231 monkeys that were randomly allocated at birth across three rearing conditions: mother rearing, peer rearing, and surrogate peer rearing. We show that the lack of a secure attachment r...

In this paper, we propose an explanation for the prominent role of manufacturers in the financing of their own product sales— so called “captive finance.” By lending against their own product as collateral, durable goods manufacturers with market power can commit to restrict production and maintain resale values in future periods, preserving rents today. Using data on captive financing support ...

In most markets, buyers differ in their ability or willingness to switch supplier. This note proposes a novel industry concentration measure that takes this heterogeneity into account. The index increases the share of captive sales, coincides with Hirschman–Herfindahl Index when none are captive, and ”pure monopoly” value 1 all captive.

The effect of outdoor rearing duration (75 v 50 days) and rearing system (outdoor v indoor based systems) of Iberian pigs on the chemical composition (fatty acid composition of fat and intramuscular fat, moisture, salt, pigment concentrations and water activity of lean meat), the instrumental colour (CIEL*a*b* system) and the sensory characteristics (descriptive analysis) of dry-cured hams were...

The goals of this study were to have an improved understanding of milk composition and to help create a suitable milk formula for cubs raised in captivity. Milk samples were evaluated for fat, fatty acids, carbohydrate, vitamin D(3), 25(OH)D(3), vitamin A (retinol), vitamin E (α-tocopherol), protein, and amino acids. Total lipids in milk did not differ for cubs (mean ± SEM = 26.60 ± 1.88 g/100 ...

The presence of the cosmopolitan deep-sea coral Eguchipsammia fistula has recently been documented in the Red Sea, occurring in warm (>20 °C), oxygen- and nutrient-limited habitats. We collected colonies of this species from the central Red Sea that successfully resided in aquaria for more than one year. During this period the corals were exposed to increased oxygen levels and nutrition ad libi...
