Lipid oxidation results from heme catalysis

Iron compounds in fish contribute significantly to lipid oxidation in addition to oxidation mediated by enzymatic activity. The main iron-containing compounds are myoglobin and hemoglobin.

Hyper-intensive nursery systems offer advantages for shrimp culture

Hyper-intensive nursery systems for juvenile shrimp production present significant opportunities for shrimp farmers to increase profits. Nursery culture results in strong, healthy and uniform juveniles with great potential for compensatory growth when stocked in production ponds. Nurseries produce a maximum number of juveniles of a desired weight, and their use can reduce production costs by shortening time in growout ponds and increasing pond efficiency through additional cycles per year.

The introduction of tilapia to irrigation reservoirs in Israel improved the efficiency of water usage and reduced the cost of water needed for tilapia culture. Although requiring considerable investment, many dual-use reservoirs were constructed and equipped for efficient harvesting.

Ideally, farmers need to create conditions that make it harder for the pathogenic Vibrio that causes AHPN to colonize animals’ stomachs and for the toxin to produce its pathology. Exclusion where possible and appropriate management of ecosystems offer hope in addressing AHPN.

Salinity tolerance of Gulf corvina, prospective aquaculture species

After six weeks of experimental culture, comparable growth and survival were recorded in juvenile Gulf corvina raised at salinities of 5, 15, 25 or 35 ppt. Coupled with stable plasma osmolality values observed in fish at the varied salinities, these results confirmed the euryhaline nature of this species, a trait that could enhance its status as a candidate for aquaculture.
