| Tamarixia triozae es un ectoparasitoide con alto potencial para su uso en programas de manejo integrado del psílido de la papa, Bactericera cockerelli. Aunque ya se produce comercialmente, no existe información de su almacenaje a bajas temperaturas, esta información puede tener importancia para optimizar la conservación de estos organismos. En el presente trabajo se evaluó la respuesta de pupas y adultos de T. triozae después de almacenarlos a 5, 8 y 10°C por 7, 14 y 21 días. Los resultados se compararon con aquellos obtenidos en testigos a 25°C y los mismos tiempos de almacenamiento. La supervivencia en adultos, después del periodo de almacenamiento, en todos los tratamientos fue superior a 95%. Aquellos almacenados a 5 y 8°C por 21 días presentaron los... |

| ABSTRACT ‘Bartlett’ pears from different harvest dates were assessed regarding to cold storage potential and reduction of physiological disorder incidence. Three harvests, the first (HD1), second (HD2), and third (HD3), were carried out at weekly intervals. The pears were assessed after the harvest, with no exposition to the temperature conditioning, after 20, 40, 60, 80, 100 and 120 days at 0 ± 1 °C and 90 ± 5% RH and after three and six days at room temperature (20 ± 1 °C). Fruit from the early harvest (HD1) showed the smallest incidence of physiological disorder during both cold and room temperature storage. The disorder symptoms became apparent in HD1 fruit after 20 days at cold storage followed by three days at 20 °C, whereas HD2 and HD3 fruit showed... |

| This study aimed to analyze the cuticle thickness and pattern of epicuticular wax deposition in 'Gala' and 'Galaxy' apple cultivars (Malus domestica Borkh,) from three Brazilian producing areas: Vacaria (RS), Fraiburgo (SC) and São Joaquim (SC) with altitudes of 971, 1,048 and 1,353m, respectively. Harvested fruit were kept under two storage conditions: regular atmosphere (RA) (0 ºC and 90% RH) and controlled atmosphere (CA) (1.5% O2, 2.5% CO2, 0ºC and 90% RH). Cuticle thickness measurements were made using LM and the deposition pattern of epicuticular wax observed with a SEM. Altitude among the apple producing areas was not a factor in deposition pattern of waxes between the cultivars but at higher altitudes, the cuticle was thicker in both the cultivars.... |

| Different methods in use for cold smoking of salmon affect product yield and quality. The combinations of filleting time (pre or post), salting methods (dry or injection), salting targets (2.5 or 4%) and smoking temperatures (15 or 25 °C) were studied during 6 weeks of 4 °C cold storage. Salting method had the greatest influence on flesh quality. Injection salting led to 15% higher fillet yield, moderate to strong gaping score, softer texture, and paler fish compared with dry salting. Pre-rigor filleting reduced fillet gaping from a moderate to minor score, but only in dry salted fillets. Smoking at 15 °C reduced yield by 0.5% in injected salted fish, compared with 25 °C. The combination of pre-rigor filleting, dry salting and 15 °C smoking temperature... |

| Among other results, it was found that when hake is handied property it maintains good quality levels up to 10 days after catch, irrespective of season. Its total storage life in boxes with ice is approximately two weeks. Although total storage life remained unchanged, it was found that quality levels tended to be significantly higher if overfilling of boxes was avoided, if the fish was gutted immediately after catch, or if hake was stored in containers with seawater. |

| Challenges the fishing ports of Ghana, notably Sekondi Port include the congestion and the deteriorating efficiency due to the increase of users and decreasing quality of catch due to the shortage and ageing of landing facilities, fish handling sheds and ice-making facilities. The Government of Ghana made a request to Japan for an extension of the wharf, construction of additional breakwater, cold storage and ice-making facility at Sekondi Fishing Port in 2010 in order to overcome these challenges. In response the Government of Japan conducted a survey for the project to promote efficiency and improvement of Ghana's fishery sector. The survey was to examine the need, relevance and urgency of the proposed project. |

| Freshly-hatched <i>Artemia</i> nauplii from various geographical sources survived storage in a refrigerator (2-4°C) at densities of 2000 per ml and above. Except for <i>Artemia</i> from Chaplin Lake and Buenos Aires, naupliar viability was very high even after 48 h storage, and did not decrease significantly after a 24 h post-storage transfer to 25°C. Neither the naupliar dry weight nor biochemical composition changed significantly during refrigeration for most strains tested. Comparative culture-tests with stored and freshly-hatched nauplii as food for juvenile marine mysids <i>Mysidopsis bahia</i> M. and larval carp <i>Cyprinus carpio</i> L. revealed similar production performances. |

| The physical-chemical quality changes in mangaba fruit were studied. The fruit which attained full development at half-ripe stage were harvested and initially stored at 6, 8, 10 and 12±1ºC for four days. After this period, the fruit were transferred to an acclimatized room (24±2ºC) and maintained for five days. For control purposes, recently harvested fruit were stored directly in an acclimatized room (24±2ºC) for six days. After the transfer and storage at 24ºC, fruit were analyzed daily for their vitamin-C, soluble solids (ºBrix), titratable acidity, pH and firmness contents. In fruit directly stored at 24ºC, there was a sharp fall in vitamin C and acid contents. The fruit firmness decrease, after four days of storage, and they turned totally ripe. The... |
