Establishing spatio-temporal profile of scombrid larvae: the Philippine Eastern Pacific seaboard in focus

Scombridae is a family of fishes consisting of 51 species in 15 genera and two sub-families all of which belong to the Sub-family Scombrinae, except the butterfly kingfish which belongs to Sub-family Gasterochismatinae. The Sub-family Scombrinae comprises four tribes, namely: Scombrini (mackerels), Scomberomorini (Spanish mackerels), Sardini (bonitos), and Tunini (tunas). Scombrids have two dorsal fins and a series of finlets behind the rear dorsal fin and anal fin. The caudal fin is strongly divided and rigid. The first (spiny) dorsal fin and the pelvic fins are normally retracted into body grooves. Lengths of the species belonging to Family Scombridae vary from 20.00 cm (7.9 in) of the island mackerel to 4.58 m (15.0 ft) recorded for the immense Atlantic bluefin tuna. Scombrids are generally considered predators of the open ocean, and are found worldwide in tropical and temperate waters. Most species of Scombrids are economically-important to the Philippines. In 2013 for example, the country's production of tunas and mackerels accounted for about 31% of the country's total production volume from marine capture fisheries and about 42% in terms of value, of which 78% of the Scombrids production volume and 80% of the value was contributed by tunas (SEAFDEC, 2015). This makes tunas the most economically-important Scombrid species for the Philippines. Establishing the spatio-temporal profile of Scombrid larvae especially in the country's Eastern Pacific Seaboard would therefore provide a picture of the abundance, distribution and diversity of Scombrid species in the Philippines.

Recording sharks and rays statistics from Southeast Asia at species level
Wanchana, Worawit; Ali, Ahmad; Putsa, Santiphong
The Southeast Asian region, which includes Brunei Darussalam, Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, Philippines, Thailand, and Viet Nam, is home to a rich diversity of sharks, rays, skates, and chimaeras (Class Chondrichthyes). According to Ahmad and Lim (2012), Ahmad et al. (2013) and Ahmad et al. (2014), at least 329 species of chondrichthyans are found to inhabit in this region from freshwater to the deep sea. This includes 174 species of sharks from 8 orders (29 families), 148 species of rays from 5 orders (19 families), and 7 species of chimaeras from two families. Ahmad et al. (2013) reported that Indonesia recorded the highest diversity of sharks with 114 species and 26 families followed by Philippines (94 species; 26 families), Thailand (64 species; 19 families), Malaysia (63 species; 18 families), Brunei Darussalam (34 species; 13 families); Myanmar (34 species; 10 families), Viet Nam (29 species; 13 families), and Cambodia with 11 species and 6 families. As for batoids (rays and skates), Ahmad et al. (2014) reported that Indonesia also recorded the highest number with 106 species and 17 families followed by Malaysia (84 species; 14 families), Philippines (66 species; 18 families), Thailand (71 species; 12 families), Cambodia (55 species; 14 families), Myanmar (44 species; 10 families), Viet Nam (38 species; 12 families), Brunei Darussalam (36 species; 11 families), and Lao PDR with 3 species and one family. Information on chimaeras however is still scanty. Until 2015, only 4 species of Hydrolagus, 2 species of Chimaera and one species of Harriotta have been recognized. Indonesia recorded 4 species of Chimaerids while the Philippines recorded 3, and Malaysia and Thailand recorded only one species. With new species continuously being discovered, the number of Chondrichthyan species in this region is expected to increase.

Purse seine fisheries in Southeast Asian countries: A regional synthesis
Hassan, Raja Bidin Raja; Latun, Abdul Razak
Several Southeast Asian countries, namely: Brunei Darussalam, Cambodia, Indonesia, Malaysia, Myanmar, Thailand, Philippines, and Viet Nam surround the South China Sea (SCS) which is one of the most important fishing areas for these coastal states, and where some of its fishery resources form shared stocks among these bordering countries. SCS encompasses a portion of the Pacific Ocean stretching roughly from Singapore and the Strait of Malacca in the Southwest, to the Strait of Taiwan (between Taiwan and China) in the northeast. The hydrography of SCS consists of continental shelf of 200 meters deep, continental slopes and deep waters down to more than 2,000 meters. In the SCS, small pelagic fisheries dominate by about 20% of the total marine capture fisheries. Living in the surface and mid-water column of ocean or inland ecosystem, pelagic fishes range in size from small coastal foraging fishes, such as herrings and sardines, to large apex predator oceanic fishes, such as the Southern Bluefin tuna and oceanic sharks. These pelagic fishes are usually agile swimmers with streamlined bodies, and capable of sustained cruising on long distance migrations. In many countries surrounding the SCS, purse seine has been commonly used to capture these pelagic fishes. The status of purse seine fisheries in the countries bordering the SCS is summarized in this article based on the information provided by the concerned countries and compiled by the SEAFDEC Marine Fishery Resources Development and Management Department (SEAFDEC/MFRDMD) during the Core Experts Meeting for Comparative Study on Purse Seine Fishery in the Southeast Asian Region organized by SEAFDEC/MFRDMD in Kuala Lumpur, Malaysia on 26-28 August 2014. The same information had also been reflected in a subsequent publication entitled 'Current Status of Purse Seine Fisheries in the Southeast Asian Region' (SEAFDEC/MFRDMD, 2015). It should be noted that the term 'South China Sea' is used in its geographical sense and does not imply recognition of any territorial claims within the area. A way forward to bring in long term sustainable purse seine fisheries in Southeast Asia, more particularly in the SCS and Andaman Sea, is also being highlighted.
