The demand for animal protein especially fish is expanding due to the population growth, increased incomes and changes in eating habits and life styles. The capture fisheries in Malaysia which supply over 70 % of the fish used for food are over-exploited, and the yield has become stagnant over the last decades and in some cases it has even declined. In addition, the balance of trade for the pas...

BACKGROUND More fish have been afforded US Endangered Species Act protection than any other vertebrate taxonomic group, and none has been designated as recovered. Shortnose sturgeon (Acipenser brevirostrum) occupy large rivers and estuaries along the Atlantic coast of North America, and the species has been protected by the US Endangered Species Act since its enactment. METHODOLOGY/PRINCIPAL ...

Alfalfa was harvested from alternate windrows as 40% DM silage or hay in small rectangular bales and fed in two 12-wk 4 x 4 Latin square trials, each with 20 multiparous lactating cows (4 with ruminal cannulas). Diets contained (DM basis) 69 (trial 1) or 66% (trial 2) alfalfa, 26 to 33% high moisture corn, 1.3% minerals and vitamins, and about 1.6 Mcal of NEL/kg of DM. In trial 1, second-cuttin...

Artificial reefs continue to be added as habitat throughout the world, yet questions remain about how reef design affects fish diversity and abundance. In the present study, the effects of reef density were assessed for fish communities and sizes of economically valuable Lutjanus campechanus 13 km off Port Mansfield, Texas, at a reef composed of more than 4000 concrete culverts. The study spann...

Little is known about the growth performance of sex-reversed, all male Oreochromis niloticus under different traditional and non-traditional culture methods practiced in India. In this study, 17"methyltestosterone treated monosex tilapia was cultured in concrete tank, flow-through system, cage, pen and earthen pond. Similar feeding regime and stocking density of fish were maintained for all the...

The transition from aquatic to aerial respiration is associated with dramatic physiological changes in relation to gas exchange, ion regulation, acid-base balance and nitrogenous waste excretion. Arapaima gigas is one of the most obligate extant air-breathing fishes, representing a remarkable model system to investigate (1) how the transition from aquatic to aerial respiration affects gill desi...

Abstract G-banded karyotyping is the most common approach for detection of genomic alterations. However, this unable to detect changes less than 5 Mb. The ability fluorescence in situ hybridization (FISH) cryptic chromosomal rearrangements exceeds resolution routine karyotype. conventional FISH targeted regions only, whereas microarray a whole-genome copy number evaluation technique with 10 20 ...

Emerging studies demonstrate that three-dimensional organization of chromatin in the nucleus plays a vital role in regulating the genome. DNA fluorescent in situ hybridization (FISH) is a common molecular technique used to visualize the location of DNA sequences. The vast majority of DNA FISH studies are conducted on cultured cells due to the technical difficulties encountered using fixed tissu...

Freshwater fisheries are central to food security in China and this remains one of the most important priorities for the growing human population. Thus, combining ecosystem restoration with economics is pivotal in setting successful conservation in China. Here, we have developed a practical management model that combines fishery improvement with conservation. For six years, a ban on fertilizer ...
