Updates in the Philippines: Where are the captive milkfish breeders?

A map is provided showing the location of milkfish rearing facilities in the Philippines. Most of the 17,443 milkfish broodstocks are located in central Philippines. A table shows details as to the rearing facility (cage, pen, pond, tank), number of broodstocks, and age. There are 13,420 broodstocks in ponds; 2,081 in cages; 842 in tanks, and 1,100 in pens. The youngest is 3 years, the oldest 23 years old.

An aquasilvifarm in the Philippines

Aquasilviculture can be defined as the integration of aquaculture with mangroves. Details are given of an example of aquasilviculture in the Philippines at Puerto Galera, Mindoro. The farm has 3 series of perimeter ponds stocked with tilapia, although milkfish, mudcrab and shrimp may be caught when entering the ponds incidentally.

A glimpse into some sea cucumbers in Panay, Philippines

Except for coastal dwellers, most Filipinos do not know what sea cucumbers are, although most must have dined on them at some time. A description is given of what sea cucumbers are and how they look, how they are processed and how they are cultured. Sea cucumbers, which belong to the families Holothuridae and Stichopodidae, have a worldwide distribution and are found in large numbers in the Indo-West Pacific region. In the Philippines, sea cucumbers have never been cultured, although it is one of the sources of dried sea cucumbers in the international market. This is most probably due to the fact that wild supply has apparently been sufficient for trading.

SOCIAL-DEVELOPMENT OF INFANTS OF MACACA-THIBETANA AT MOUNT-EMEI, CHINA

The development of infant Macaca thibetana was studied at Mount Emei, China, and compared to that of other macaque species. It was found that there are many common features in the process of infant socialization in species of the genus Macaca: mothers play an important and active role, other group members influence the infants' development to a greater or lesser extent and play is a major activity in the life of infants. Some differences were found to exist, however, between macaque species. These included differences in maternal care behaviour such as 'len', leaving time and weaning time. Paternal behaviours were also found to vary within and among species. Tibetan macaque males care for infants extensively, and they may use infants as an agonistic buffer. The natural and social environment may also influence differences between macaque species in infant development.

NATURAL FOODS AND THEIR ECOLOGICAL IMPLICATIONS FOR MACACA-THIBETANA AT MOUNT EMEI, CHINA

Natural food plants of partly provisioned groups of Macaca thibetana included about 196 species belonging to 135 genera and 72 families. The macaques consumed mainly bamboo shoots and fruits for about 2 months in autumn, whereas they relied on active or passive provisions from visitors, a variety of structural parts of plants and a small amount of invertebrates in late spring and summer and ate mainly mature leaves and bark for the rest of the year. About half of the species eaten came from the dense herb and shrub layers. This forest-dwelling species shows a distinctive feeding and foraging pattern in comparison with other macaques, explaining why M. thibetana has the largest body weight of all macaques.

DRAMATIC CONSEQUENCES OF FOOD HANDOUTS TO MACACA-THIBETANA AT MOUNT-EMEI, CHINA

Food handouts to Macaca thibetana at Mt. Emei have had dramatic consequences for both man and monkey as tourism has increased over the last decade. Food handouts and human submissive behaviour facilitate beg-robbing by the monkeys. which can be regarded as a mixed conditioning chain. Because of their lack of understanding of primate behaviour and resulting inappropriate responses, many visitors have lost possessions and have been severely frightened or even injured; in fact there have been 1 0 deaths as an indirect result over that past 8 years. The appropriate human response proved to be the display of dominance to maintain a distance from a beg-robbing monkey. Road-ranging macaques have also been injured or killed by visitors to obtain meat or bones or merely for amusement. Attempts should be made to eliminate the negative effects of food handouts by increasing visitors' awareness of behavioural and ecological aspects and through aversive conditioning of the macaques.
