Cicely Tyson, her memoir just out, was active to the end


first_imgNEW YORK (AP) — Cicely Tyson was active to the end, in the middle of promoting her memoir “Just As I Am” when she died at age 96. Published earlier this week, “Just As I Am” was No. 1 on Amazon.com within hours of her death Thursday, displacing a bound edition of Amanda Gorman’s inaugural poem “The Hill We Climb.” Many media outlets had been celebrating Tyson and her memoir. “CBS This Morning” put online its week-old interview with Tyson, in which she was asked what it was she wanted the world to remember about her. “I’ve done my best. That’s all.” she said..last_img


SEAFDEC reminds shrimp growers to avoid stocking ponds during cold months

TO PREVENT the entry of shrimp diseases, shrimp farmers areadvised not to stock their ponds during cold months if their farms are notbiosecurity-compliant or fully equipped to prevent the entry of shrimp diseases. Estilo also recommends that shrimp farmers, especially thosewhose facilities are not fully equipped to prevent the entry of land, water andair-borne pathogens and disease carriers, to consider having only oneproduction run per year within the warmer months. “A higher rate of culture success can be attained during thewarmer months from April to October,” said Mr. Victor Emmanuel Estilo, shrimppond culture expert of SEAFDEC/AQD. By Rossea H. Ledesma Last year, SEAFDEC/AQD successfully demonstrated tigershrimp culture runs when it harvested 2.8 tons and 4.4 tons from a 5,000 and8,000-square meter pond in October and November last year. To maximize utilization of ponds, Estilo suggested growinghigh-value marine fish species such as snappers (maya-maya) and Asian sea bass (bulgan)during cold months. According to SEAFDEC/AQD chief Dan Baliao, the technologyused to achieve this harvest is “easy to adopt and apply” for shrimp farmersand is “proven effective if given the proper aquaculture management.”/PN Based on satellite readings provided by the National Oceanicand Atmospheric Administration in the United States, sea surface temperaturesin Western Visayas are lowest in February where it reaches a monthly averageminimum of 25.5 degrees Centigrade in Iloilo and Negros Occidental. center_img A shrimp pond at SEAFDEC/AQD’s Dumangas Brackishwater Station, ready for harvest in October 2019, seen here with paddle wheels and bird scare devices on top.

A study by Dr. Eleonor Tendencia, scientist at theAquaculture Department of the Southeast Asian Fisheries Development Center(SEAFDEC/AQD), showed that a drop in temperature weakens the immune response ofshrimp, thereby making them prone to infection. The study cites the pattern ofwhite spot syndrome virus outbreaks in tiger shrimp when atmospherictemperatures are low. Oplan Balik Sugpo “Inter-cropping with these predatory fish species in shrimpponds is advantageous since they prey on wild disease-carrying crustaceans;thus, effectively breaking the chain of contamination within the pond,” saidEstilo. Recurring disease outbreaks are considered the most seriousproblem faced by shrimp farmers. With this constraint, SEAFDEC/AQD under itsbanner program “Oplan Balik Sugpo,” intensified its research activities onidentification, detection, prevention, and treatment of diseases plaguing theindustry. It has also come up with protocols and is studying other variables toprevent the occurrence of diseases in shrimp stocks. Even then, shrimp farmers should always take extraprecautions to prevent the entry of diseases by using high health or specificpathogen free (SPF) postlarvae (PLs), effective pond water filtration systems,de-contamination facilities (tire and foot baths) at single farm and pondentrances, and crab fences and bird-scaring devices among others. Experts from the Aquaculture Department of the SoutheastAsian Fisheries Development Center (SEAFDEC) warn that shrimps get stressedwhen exposed to temperatures below 27 degrees Centigrade, predisposing them todiseases.last_img read more
