在礁坪上的海参鲍鱼的苗圃和生长培养:使用不同培养容器生长和存活的比较Junemie榛子;Mediavilla,乔纳斯p;索利斯,艾伦福罗;Sibonga瑞玛;弗朗西斯·帕特里克·阿利坎特;这项研究的目的是比较四种不同的培养容器(笼子、回收油容器、托盘(对照)和管)在孵育室和在礁滩上培养海参鲍鱼的生长。幼儿园文化,早期青少年鲍鱼意味着shell (SL)长度为1.30±0.006厘米,平均体重(BW) 0.45±0.007 g储存在容器在印第安纳州100−2和长大,直到他们达到所需的3厘米SL大小出文化在三四个文化的容器。出文化,少年鲍鱼是从幼儿园文化与平均3.23±0.018厘米的SL和平均BW 7.33±0.131 g储存在容器在50州的m−2长大,直到他们收获的5厘米SL鸡尾酒在三四个文化的容器大小。在回收的容器、托盘和试管中培养90天(DOC)可获得3cm SL的生长大小，而在相同的容器中180 DOC可获得5cm SL的鸡尾酒大小。 Abalone reared in tubes had the highest mean SL after 90 DOC in nursery culture (3.21 cm), while those in trays after 180 DOC in grow-out culture (5.30 cm). However, at the end of the nursery and grow-out culture, there were no significant differences in mean SL among the abalone reared in these three culture containers. In both culture phases, abalone reared in cages had the lowest mean SL, 2.88 and 4.44 cm, respectively. Survival was highest in trays (98.64%) during nursery culture and in tubes (96.57%) during grow-out culture. With comparable results in recycled containers, trays, and tubes for both growth and survival at the nursery and grow-out phases, tubes are recommended for use when culture is to be done on reef flats. Tubes are the most stable and durable among the four culture containers tested. They can withstand strong winds and waves and may be reused for several culture runs.

孵化饲养的黄斑兔鱼(Siganus guttatus, Bloch 1787)幼虫早期碘和甲状腺激素水平的变化
孵化饲养的橙色斑点兔鱼Siganus guttatus (Bloch 1787)幼虫发育早期碘和甲状腺激素水平的变化艾琳c;雷克斯费迪南德Traifalgar;de Jesus-Ayson, Evelyn Grace;Karen Grace S. Andrino-Felarca;本文阐述了碘和甲状腺激素、甲状腺素(T4)和三碘甲状腺原氨酸(T )在孵化兔(Siganus guttatus)仔鱼发育早期的发育情况。本研究测定了兔鱼仔鱼孵化后0、10、20、30、40和50 d碘含量、T< >4 >和T< >3 >组织含量。正常饲养条件下，碘(11.98±4.3 nmol g−1)和甲状腺激素(T4: 0.09±0.01 nmol g−1;T3: 0.01±8.5E-05 nmol g−1已从新孵出的幼虫中检测到，其存在可能来自母系。碘浓度在10 DAH时达到峰值(1416.43±149.6 nmol g−1)，显著高于20、30、40和50 DAH时的水平。 The levels of THs gradually increased as the larvae developed with T4 (0.96 ± 0.05 nmol g−1) and T3 (0.03 ± 0.004 nmol g−1) exhibiting a peak on 20 and 30 DAH, respectively, which coincided with the onset of metamorphosis. Thyroid hormone levels gradually decreased which coincided also with the completion of metamorphosis. The present findings indicated a pattern of the rise and fall in iodide and thyroid hormone levels during larval development and its role in metamorphosis of rabbitfish larvae. The study has reported for the first time, the changes in iodide and thyroid hormone levels during the early developmental stage in hatchery-reared rabbitfish and the results are in agreement with those vital actions of thyroid hormones in other fish species.

2019冠状病毒病大流行期间，菲律宾伊洛伊罗大学生的信息寻求行为和知识水平、预防措施和恐惧安德森,克里斯汀;迈克尔瑞安Oducado;Luceno默娜;文斯Palcullo;COVID-19大流行正在对全世界公民的健康、社会和经济福祉造成毁灭性打击。高发病率和死亡率以及缺乏疫苗引起了人们的恐惧，无论年龄、性别或社会地位如何。人们的恐惧被各种媒体传播的错误信息加剧了，尤其是在社交媒体上。菲律宾大学生是世界上使用互联网最多的人之一，他们在社交媒体上非常活跃。因此，他们很容易产生错误信息。 This paper aims to ascertain the levels of knowledge, precaution, and fear of COVID-19 of the college students in Iloilo, Philippines, and determine the effects of their information-seeking behavior on the variables above. This paper is a cross-sectional survey that used a qualitative-quantitative method and snowball sampling technique. Data were gathered among 228 college students using an online survey instrument a few months after the pandemic began. College students were knowledgeable of the basic facts about the highly infectious COVID-19. However, the majority were inclined to believe the myths and misinformation regarding the pandemic. Television was the primary, most believable, and preferred source when seeking information. The Internet as a preferred source of information was significantly associated with a high level of knowledge. In contrast, the information sourced from interpersonal channels were found to make college students very cautious. The local presence of COVID-19 cases had caused college students to fear, likely exacerbated by the plethora of information about the pandemic, mostly from Facebook. This is the first study conducted on the effects of the information-seeking behavior on the levels of knowledge, precaution, and fear of COVID-19 of the college students in Iloilo, Philippines.
