Sciaenidae Assessment Workshop



Croakers or drums, commonly known as “ikan gelama” in Malaysia, are common fishes found in tropical coastal areas, estuaries and shallow waters. Croakers make up the bulk of trawl fish species in Malaysia and are also considered an important fisheries resource in many other countries. To date, ~300 species of croakers have been identified, which include local species familiarly known as “gelama pisang”, “gelama jarang gigi”, “gelama papan” etc.

The croaker’s swim bladder or “fish maw” is a valuable commodity served in traditional Chinese cuisine during hospitality feasts. As a result of this fish maw trade, however, there has been increased fishing pressure on larger-sized croakers for their swim bladder, causing some species such as “Chinese bahaba”, Bahaba taipingensis to face critically endangered status. In recent decades, declines in both fish catch yields and sizes due to heavy fishing pressures has gradually prompted the replacement of wild-caught common food fishes to those from aquaculture sources.

During 26th June – 1st July 2016, National Museum of Marine Biology and Aquarium (NMMBA) – Global Sciaenidae Conservation Network (GSCN) together with the International Union for Conservation of Nature (IUCN) Species Survival Commission (SSC) Sciaenidae Red List Authority, Boston Bio-Amazonia Conservation International, National Sun-Yat-sen University and Xiamen University, co-sponsored the “Global Sciaenidae Conservation Network International Conference” held a series of “Species Red List Conference, Training Course and West Pacific Sciaenidae Red List Assessment Workshop”.

During this workshop, a comprehensive red list assessment of ~60 species western Pacific croakers was completed, which will be used to determine the survival chances of threatened fish species in the ocean. For example, fish species, such as common croaker in Malaysia “gelama jarang gigi”, which has not reduced in catch yields in the past decade will be listed as of “least concern”, while those species, such as the wild “Japanese meagre”, Argyrosomus japonicus that have small yields or are exorbitantly priced in the first trade will be listed as “endangered”.

How about the croakers from Indian Ocean? You are welcome to observe the red listing process in the workshop! And, who have information in regard to croakers are encourage to attend the workshop to ease the red list assessment. The outcomes of such discussions and other conservation level assessments from scientists in the meeting can be used as important references for future conservation policies and management of the coastal fishery resources. It not just croaker fishes, but also other valuable marine life groups need to be considered in order to  establish a sustainable coexistence between humans and biodiversity.
