Dennis Rouse, Director Auburn, Alabama ACKNOWLEDGMENTS The basic data on length-weight measurements of Thai fishes were obtained by biologists of the Thai Department of Fisheries on fish taken by sampling populations in rivers and impoundments under the direction of Ariya Sidthimunka. The preparation of these data for publication was financed through United States Agency for International Development Project No. AID/csd 2270 T09 under direction of H. S. Swingle, Director, International Center for Aquaculture, Au- burn University Agricultural Experiment Station. Length-Weight Relationships of Freshwater Fishes of Thailand 1 ARIYA SIDTHIMUNKA 2 L ENGTH-WEIGHT data on fishes are useful to biologists for a variety of purposes. The data presented are especially val- uable because they are derived from measurements of fishes taken from lakes, swamps, and reservoirs in major river sys- tems throughout Thailand over an extended period of time. Since the data are derived from fishes taken from all types of natural waters over a period of years, they can be con- sidered typical average weights of that species for each of the given lengths. Along with length-weight data the con- dition index (K) is presented and was derived as follows: W x 10 5 K L 3 where: W = weight in grams, L = total length in centimeters K is an expression of weight of a fish per centimeter of length. Since the characteristic shape of some fish changes with increase in length, K is not a constant for a species, but changes gradually with increase in length and age of fish and serves primarily to demonstrate the length where this change in body shape is most evident. A more meaningful expression of condition can be obtained by calculation of another measure of condition of a popula- tion or of an individual fish. This is the relative condition index of Le Cren (Kn): 3 W Kn = A, where: W W = weight of an individual or the average weight of individuals of a certain length, and W = the calculated average weight for the above length from the equation W =aLb, where a and b are constants. W is the calculated average or standard weight for a given total length, L, of a particular species under conditions in Thailand, and are presented in the tables that follow. Kn, A may be calculated from these standard W's, and expresses 1 Thai Department of Fisheries, Inland Fisheries Division, Chertchai Amatayakul, Director. 2 Chief, Fishery Biological Survey Unit.

Calculated weights are from general equations of the form A W = aLb A where W = weight in grams, L = total length in centimeters, a - a constant and b an exponent. This relationship was calculated in its linear logarithmic form where A Logl 0 W - log 1 ca + b loglo 0 L Very often one equation will not adequately describe the complete range of lengths and weights for a particular species. As a result two or even three equations are some- times used to describe a set of data. The range over which a single standard length-weight equation was computed was selected by determining the point where the increment of increase or decrease in the condition index changed signifi- cantly in magnitude. The parameters log (a) and b for each equation and the intervals to which they apply are presented in the Appendix. For example, from the standard table, Tilapia nilotica of A 12 cm total length has a standard W= 832.3 grams. If pla nin from a rice field with a total length of 12 cm weighs 40.0 grams, then 40.0 Kn- 32. 1.24, indicating that the fish from the rice field was 24 per cent heavier at the same length than the standard average for the entire country. However, if the weight of a 12-cm pla nin taken from a swamp during the dry period has a weight of 28.0 grams, then 28.0 Kn 32.3 0.87 indicating that the fish weighed only 87 per cent as much (or 18 per cent less) than the average and is growing very slowly or even losing weight. This may be due to over- crowding of fish, reduction in food due to gradual reduction in water area during the dry period, or to other unfavorable conditions for fish growth. A centimeter grouping may be too large for a meaningful comparison of estimated and observed weights. For ex- ample, if a fish is 12.3 cm, its estimated weight can be com- puted using the log (a) and b values listed in the Appendix. In the case of pla nin, the estimated weight (W) would be 35.07 for a 12.3 cm fish. A W 3= 5.07 = antilog 1.5449 = -2.08 + 3.28 log 12.3 Seasonal changes in condition as fish approach the spawn- ing period may increase their weight by an average of 10 per cent without corresponding changes in length, thus giving Kn values above 1. This is due to gradual increase in weight of the gonads, which is followed by sharp decrease in body weight immediately following spawning. There will be, in certain species, differences in condition due to sex of the fish. This is often related to their role in spawning. In cer- tain species such as tilapia, the female grows slowly during the spawning period because of the energy required for fre- quent spawning. K, may be used as an indication of relative rapidity of growth, because the weight per unit length of a fish is greater when it is growing rapidly than when growing slowly. That is, the maximum depth and maximum width, and conse- quently the volume and weight of a fish, is greater when growth is rapid, producing a relatively short, heavy fish in "good condition." Conversely under unfavorable growth conditions, a fish appears long and thin, and in "poor condi- tion." Under prolonged periods of starvation the fish loses in girth and weight, while the bony skeleton prevents much change in length. Relative condition of fishes thus may often summarize average, good or poor conditions for growth in a given body of water, expressed by Kn values of 1.0, above 1.0 and below 1.0 respectively. Poor condition of individual fish in a population having average or good condition may be caused by parasites, dis- ease, or abnormal physiological problems. Length-weight data are tabulated for each species in cen- timeters and grams. Data consists of the centimeter length, the number of fish measured in this centimeter length, the minimum and maximum weights, the average weight, the A computed standard weight or W and the condition index K. Species are listed alphabetically by scientific name. The computer program previously used to calculate length- weight of Alabama fishes (1964, 1965) was modified for this study by Wayne E. Swingle of the Marine Resources Di- vision of the Alabama Department of Conservation, who also prepared the data for processing. Assisting in the prepara- tion of the report were Drs. W. D. Davies and E. W. Shell of the International Center. Credit is also due to Dr. R. M. Patterson, Research Data Analysis, Auburn University Agricultural Experiment Station for suggestions and super- vision of the data computations. LITERATURE CITED SWlNGLE, WAYNE E. 1964.
