The objective of this research was to evaluate the sex reversal technique using 17α--methyltestosterone (MT) hormone, submitted to temperature modification of fry Nilo tilapia storage, aiming to get the data of sex reversal combined with growth performance and fry survival. The experiment was performed at UFLA Fish Culture Station, using tilapia fry (0,008 ± 0.002 g e 0,9 ± 0.1 cm) obeying a totally randomized experimental delineation in a factorial scheme 4x4, in 4 temperatures (26º, 28º, 30º, 32ºC) and 4 hormonal doses (0, 20, 40, 60mg of MT/kg of ration) during 28 days, with 5 repetitions. As temperature raised, weight gain rate, size and survival increased (p<0.01); however, this temperature raise was not effective in modifying males ratio (p>0.01), which occurred only due to the used hormone treatment. The dose of 40 mg of MT/kg of ration provided similar results to those of 60mg of MT/kg of ration. Hence, the temperature band from 26º to 32ºC does not affect sex reversal rate, but temperatures around 30ºC improves the performance of tilapias related to the growth and survival, and the dose of 40 mg of MT/kg of ration is enough to achieve monosex populations.

Integrating fish and paddy culture may enhance the production with maintaining equitable use of the available land and human resources to ensure global food security. Hence the present study has been carried out to explore the possibility of culture of fish, Channa punctatus in paddy fields with/without supplementary feed. Four treatments (T1: No fish, no pesticide in paddy fields; T2: Fish in paddy fields without pesticide exposure; T3: Fish in paddy fields with are commended dose of pesticide and T4: Fish in paddy fields with pesticide dose as per farmers) were maintained in both experiments (with/without supplementary feed) in 120 m2 paddy plots. Farmers’ treatment without fish was also considered (T5). Fingerlings (15.50±0.40 g) were stocked with 1 fishper 3m2. Water quality, growth performance, carcass composition, paddy yield and economics were studied. Water quality remained in the optimum range for fish culture (D.O. 4.-7.1 mg l-1, pH 7.5-8.8).Growth performance and carcass composition revealed significantly (P<0.05) higher valuesin T2(SGR: 52.03, 129.73; crude protein: 14.8%, 15.0%). The values for paddy productions and economics increased from T1(24±0.326 q ha-1 and INR 32,850.00) to T3(55±0.475 q ha-1and INR 111,672.00), decreased thereafter. Results of supplementary food experiments clearly revealed that although fish growth/yield was higher in T2 (659±0.514 kg ha-1), rice production per hectare (57±0.891 q ha-1) and net revenue gain (INR 237,457.00) was high in T3 with recommended pesticides use. Thus, fish-cum paddy culture can yield economic benefits contributing significantly towards sustainable food security.

The Lochbuie Marine Institute on the Isle of Mull (Inner Hebrides), established in 1886, had links with the short-lived National Fish Culture Association of Great Britain and Ireland (inaugurated 1882). Its amalgamation with the Scottish Marine Station at Granton (Edinburgh) was informally suggested in 1887, but it ceased to exist about this time.

Major Benefit

In the last three decades aquaculture is a rapidly developing sector worldwide and antibiotics are used popularly as growth promoter. Antibiotic use was banned because research proved that antibiotic has caused many effects on environment and human health. Therefore, finding antibiotic alternatives is the first priority. The most prospect products today are probiotic and prebiotic. β-glucan is one of the immunostimulants which showed a variety of benefits to the health of many aquaculture species. In this paper only the results of β-glucan, a kind of prebiotic supplied in aquaculture, were summarized. The major benefit of β-glucan are to boost growth, to reduce mortality, to enhance tolerance or stress resistance to environmental or pathogen challenges. Although the applications of β-glucan are popular worldwide, its use in aquaculture in Vietnam is still limited. This paper provides an important reference for β-glucan utilisation which may help to develop a sustainable aquaculture in Vietnam.
