Effects of pH and salinity on growth and survival of juvenile sea cucumber Holothuria scabra (Jaeger, 1833)
Abagat, Christian M. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2012-03)
Sea cucumber aquaculture could provide a solution to both enhance declining wild sea cucumber populations through restocking and provide sufficient beche-de-mer product to satisfy the increasing Asian market demand. The growth and survival of hatchery-reared Holothuria scabra juveniles at different pH-salinity levels were investigated. Juveniles were exposed for 14 days in six pH-salinity levels: Trt 1 (pH 6.5 — 6.7, 26-28 %o), Trt 2 (pH 6.5 - 6.7, normal salinity), Trt 3 (pH 7.0 - 7.2, 26-28 %o), Trt 4 (pH 7.0 — 7.2, normal salinity), Trt 5 (normal pH, 26-28 %o) and Trt 6 (normal pH, normal salinity) as the control. Multivariate analysis of variance (MANOVA) with repeated measurements revealed that pH and salinity had a significant effect on growth (length, width, and weight) and survival of H. scabra juveniles. Slight seawater desalination combined with high acidification (pH: 6.5-6.7) had lethal effects on H. scabra juveniles. While H. scabra juveniles could be reared in seawater with pH ≥ 7.0- 7.2 and salinity ≥ 26-28 %o, ambient seawater conditions remained the most suitable in rearing H. scabra juveniles for optimum growth and survival.
Punjabi Indians in Iloilo City
Acosa, Jenelie A. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2006-03)
Punjabi migrants can be found in the various parts of Iloilo City. They have been part already of the lives of many Ilonggos. A study concerning them would help the Ilonggos understand these people better. This would also be valuable in the promotion of harmony and understanding between these migrants and the Ilonggos. Furthermore it would also bridge the gap that existed between these two groups of people.
This study is about Punjabi migrants in Iloilo City. It focuses on the factors that influenced them to move to Iloilo City, their life, future prospects as well as difficulties encountered and adjustments taken in their stay in Iloilo City.
Specifically this study attempts to a) gather basic information about Punjabi migrants in Iloilo City b) identify and discuss the factors behind their migration to Iloilo City c) determine the difficulties encountered by these migrants and the adjustments they have taken to cope with these difficulties that they have encountered d) describe their life in Iloilo City e) determine the prospects regarding their business and back migration.
The study made use of the library-research method as well as individual and group interviews of both Punjabi migrants and selected Ilonggo informants in order to meet the objectives of this study.
Several factors influenced the Punjabi migrants to move to Iloilo City. Some of these factors can be attributed to their place of origin. These factors include: lack of economic opportunities, hesitance to go into farming, unfavorable living conditions, and limited community amenities. On the other hand, there are factors that can be attributed to their place of destination, Iloilo City. These factors include: presence of friends and relatives, better economic opportunities and availability and accessibility to community services. In Iloilo City, they encountered difficulties that they were able to adjust. They engaged in the business of peddling and lending for them to earn their living. They still preserve some of their own customs and practices identifiable to them, although they are now living in Iloilo City. In the future, they would like to expand their business, and they would like to entertain the possibility of back migration.
Geochemical association of Cr, Cu, Ni, and Pb in the sediments of Iloilo River estuary
Arban, John Paul B. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 2005-04)
The geochemical association of Cr, Cu, Ni, and Pb in the sediments of Iloilo River Estuary has been studied using a modified Tessier’s sequential extraction procedure. The results obtained show that most of the metals studied are mostly associated in the residual and organic matter fractions of the sediment samples (Cr: 66.26% - 74.36% in the residual,15.43% - 24.08% in the Fe-Mn oxide fraction, 8.14% - 12.71% in organic matter fraction, and 0.000% - 2.996% in the exchangeable/carbonate fraction; Cu: 39.30% - 46.73% in the residual, 12.00% - 52.18% in the organic fraction, 3.227% - 11.41% in the Fe-Mn fraction, and 0.000% - 17.43% in the exchangeable/carbonate fractions; Ni: 42.75% - 57.02% in the organic matter fraction, 24.93% - 39.33% in the residual, 5.814% - 14.15% in the Fe-Mn fraction, and 5.504% - 13.12% exchangeable/carbonate fraction; and Pb in sample AAA-21: 48.02% in the residual, 38.55% in the organic matter fraction, and 7.33% in the Fe-Mn fraction, and 6.078% in the exchangeable/carbonate fraction). The analysis of the total metal concentrations of the sediment samples taken from Iloilo River are found to be above the reported concentration of uncontaminated sediment except for Pb in sediment sample AAA-21 (Chromium: 102.1 ug/g - 150.5 pg/g; Copper: 62.56 pg/g - 111.7 pg/g; Nickel: 53.40 pg/g - 75.44 pg/g; and Lead in sample AAA-21: 22.21 pg/g). The study shows that about 50% of the total metal concentration in the sediment samples are bioavailable to the aquatic organisms.
Species composition, abundance, and distribution of sea anemone in the intertidal zones of Taklong Island and vicinity, Nueva Valencia, Guimaras
Arisola, Danielle Vanessa E. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2007-04)
Sea anemones are large solitary polyps that inhabit marine environments. They are the ocean dwelling members of Class Anthozoa under Phylum Cnidaria. These carnivorous animals are common along sea shores, in bays and estuaries but are never found in fresh waters. Sea anemones form a symbiotic relationship with many other marine animals which include anemonefishes and anemoneshrimps. Due to the very little information known about sea anemones in the Philippines, this study was conducted, which specifically focuses on the species composition, abundance, and distribution of sea anemones along the intertidal zones of Taklong Island and vicinity, Nueva Valencia, Guimaras. A total census was done along the intertidal areas around Taklong Island which includes five specific areas namely, Salangan (UP channel), Likuan (area from Salangan going to Takpan-lapad), Takpan-lapad, Kalaparan, and Talisay Cove; and Piagao Cove of Tandog Island. Five out of the 10 host species of sea anemone are found along the intertidal zones of Taklong Island and vicinity: Entacmea quadricolor and Macrodactyla doreensis which belong to the family Actiniidae; Heteractis crispa and Stichodactyla gigantea which belong to the family Stichodactylidae and Cryptodendrum adhaesivum which belongs to the family Thalassianthidae. Heteractis crispa was the most dominant species, comprising 77% of the total sea anemone population, followed by Stichodactyla gigantea with 11%, then by Entacmea quadricolor and Cryptodendrum adhaesivum with 5%. Macrodactyla doreensis was the rarest species comprising only 1.3% of the total population. All 5 species of sea anemones were host anemones that harbored a variety of marine organisms namely anemoneshrimps, clownfishes (Amphiprion clarkii, A. frenatus, A. perideraion, A. ocellaris, and Premnas biaculeatus) and an anemonefish Dascyllus trimaculatus. Some of these anemone-fish relationships are specific, such as the relationship of Amphiprion frenatus to Entacmea quadricolor. The different species of sea anemones varied in their locations, some species are located only in sandy substrates, some only in coralline substrates and some in both. Distribution of each species along the 6 areas included in the intertidal zones of Taklong Island and vicinity also varied. Species such as Cryptodendrum adhaesivum and Macrodactyla doreensis were found only in Talisay Cove while the other species were distributed along the 6 areas. Piagao Cove contained only Heteractis crispa and Talisay Cove contained all 5 species.

Apolinario, Charmaine Joy B. and Tuto, Agnes Jill D. (March, 2004). Concept of Friendship and Social Network of Children in Dao Elementary Central School, Capiz. A research project submitted to the Division of Social Sciences, University of the Philippines in the Visayas, Miag-ao Iloilo. This is a descriptive study of children’s concept of friendship and their social network. This sought to know the concept of children about friendship and how they form their social network. Likewise, it also examined the kind of relationship among children. A total of sixty (60) participants were randomly chosen in the study. Out of the total participants, 29 were males and 31 females. The participants were obtained from Dao Central School Capiz using fishbowl method of simple random sampling. In gathering data, an open-ended questionnaire, Furman Friendship questionnaire and the Kite Network were used. Percentage, frequency distribution and average mean were used as tools of analysis. Friendship of children is determined on the basis of the good attitude that friends have to each other. The importance of gender and age were emphasized in viewing friendship and in forming children’s social networks. School serves as a venue to where children find their friends, children also gain friends through texting. In children’s social network, children were closely interconnected to same age and gender friends.
