Comparing triploid and diploid growth and mortality in farmed oysters, Crassostrea virginica, in the northern Gulf of Mexico
(2018-02-05)
The significance of the triploid advantage, in terms of growth and survival, varies across studies and environmental conditions. A meta-analysis was performed with 30 studies using chemically induced triploids and triploids ...
A Comparison of Ageing Methods in Red Snapper Lutjanus campechanus
(2014-04-23)
Sectioning otoliths and counting annuli is an accepted method for ageing of red snapper (Lutjanus campechanus). To reduce effort, time, and costs, whole otolith increment counts were compared to sectioned otolith increment ...
Comparison of crystalline lysine and intact lysine used as a supplement in practical diets of Channel catfish (Ictalurus Punctatus) and Nile tilapia (Oreochromis niloticus)
(2015-12-10)
Lysine is an essential amino acid commonly deficient in practical diets especially those contain high levels of plant protein ingredient, resulting in reduced growth and feed efficiency of aquatic animals. Supplementation ...
A Comparison of Fish and Epibenthic Assemblages on Artificial Reefs With and Without Copper-Based Anti-Fouling Paint
(2008-05-15)
Artificial reefs attract fish, but whether or not actual production occurs remains
unclear. To examine this question, fish and epibenthic assemblages were compared
between reefs with and without copper-based anti-fouling ...
Comparison of Ictalurid Hybrid Crosses (Ictalurus punctatus x Ictalurus furcatus) in Floating In-Pond Raceway Systems
(2015-05-11)
With the US catfish industry facing higher feed costs and stiff international competition, producers are beginning to adopt intensive alternatives to traditional pond culture. Among these are split pond systems and in-pond ...
A comparison of the size and age distribution of red snapper Lutjanus campechanus to the age of artificial reefs in the northern Gulf of Mexico
(2011-04-12)
Size and age of red snapper, Lutjanus campechanus, were sampled from April through November 2010 and compared with the age of the artificial reef at the site of capture. Artificial reefs were deployed in 2006 (n=20, 4 ...
Comparisons Among Channel Catfish Ictalurus punctatus, Blue Catfish I. furcatus, Channel ♀ × Blue ♂ Hybrid Catfish and Transgenic Channel Catfish for Growth, Cold and Salinity Tolerance
(2017-04-12)
Two studies were performed related to salinity tolerance and the potential effect of climate change on genetic choices for catfish farming. The first study examined the growth rate and survival rate among channel catfish ...
Comparisons of Growth Hormone Transgenic Channel Catfish (Ictalurus punctatus), and Channel Catfish Transgenic for Gonadotropin Releasing Hormone Knockout Genes Grown in Earthen Ponds at High Density
(2018-11-15)
The objective of the experiment was to compare the growth rate and sexual maturity score of growth hormone transgenic channel catfish, transgenic sterilization channel catfish, and non-transgenic channel catfish at high ...
Consequences of Decreased Water Temperature Caused by Aerator-Induced Evaporation on Growth of Pacific White Shrimp Litopenaeus vannamei in Ponds
(2016-07-25)
Two studies were performed related to water temperature in aquaculture ponds. The first study evaluated the influence of aeration on evaporation and water temperature in ponds, and compared the effects of daytime and ...
Construction of a high-density high-resolution genetic map and its integration with BAC-based physical map in channel catfish
(2015-12-10)
Catfish is the leading aquaculture specie in the United States of American. However, the catfish industry is facing great challenges due to devastating diseases, high production cost, high feed and energy cost and international ...
Consumer adaptation mediates top-down regulation of ecosystems across a nutrient gradient
(2016-03-07)
Individuals within a species frequently differ in important traits, and these differences are known functions of genetic, epigenetic, and environmental influences. While evolutionary biologists have been studying ...
Controlled Spawning of White Catfish, Ictalurus catus, and Brown Bullhead Catfish, Ameiurus nebulosus, Using Carp Pituitary Extract and LHRHa
(2013-01-03)
If successful artificial spawning techniques can be developed, white catfish, Ictalurus catus, and brown bullhead, Ameiurus nebulosus, may have the potential to become model organisms for accelerated catfish genetics ...
Cryopreservation of blue catfish stem cells for conserving genetic resources and xenogeneic transplantation
(2020-05-13)
In the United States, channel catfish (Ictalurus punctatus) ♀ × blue catfish (I. furcatus) ♂ hybrids now account for 70% of total freshwater aquaculture production. Hybrid fry production can be improved by cryopreserving ...
Culturing African Lungfish (Protopterus sp) in Uganda: Prospects, Performance in tanks, potential pathogens, and toxicity of salt and formalin
(2013-12-11)
Culturing species resilient to drought and stressful water quality conditions may be a significant part of the future of African aquaculture. Air breathing fishes potentially have a role in low-management culture systems ...
Current Distribution and Habitat Use of the Threatened Snail Darter (Percina tanasi) in Alabama
(2019-04-16)
The distribution of many fishes in larger rivers is poorly known, in part due to the difficulties of sampling them. This is especially true for small -bodied or rare species, such as the Snail Darter (Percina tanasi). This ...
