12 Eggs and larvae: Eggs are pelagic, transparent, 0.7mm to 0.9mm in diameter, with single oil globule. Larvae of Rastrelliger has fairly stubby body with thirty myomeres, big eyes, wide mouth, coiled intestine and a large head devoid of opercular spines. Pigmentation is less in very early larvae. The earliest record of larvae from the Arabian sea and Bay of Bengal (1967) comprisied of only three larvae measuring 2.7mm, 3.1mm and 5.3mm (Figs 1-3). The 2.7mm larva has thirty well-defined myomeres, of which seven are abdominal and twenty-three are caudal. The alimentary canal is short and single coiled, the coiling being through the right side. The length of head measures 0.6mm, and height 0.6mm. The depth of the body at the region of the stomach is 0.7mm. The mandibles, maxillae, cleithra and opercula are ossified to a greater degree than the rest of the skeletal elements. The notochord is straight, and partly ossified. Mouth is rather wide, and the inner corner of mouth extending up to the base of the middle eye. The diameter of eye measures 0.3mm. The eyes are pigmented. The dorsal and anal fins are represented by the long finfold that extends through out the length of the body. The pectoral fins are represented by two flattened membraneous finfolds one on either side. The caudal has a symmetrical appearance with the tip of notochord passing through the centre. The dorsal part of the larva is quite unpigmented, whereas ventral part exhibits certain definite pattern of pigmentation. There are two pigment spots just below the stomach. Located at the anterior and posterior margins of the anal opening two pigment spots are noticeable. Posterior to the anal opening, a row of melanopores numbering up to fifteen is seen on the ventrolateral margin of the myomeres. They extend from 8 th to 29 th myomeres. But the 14 th, 15th,18 th and 30 th myomeres lack this pigmentation. The 3.1 mm larva has a more stubby bodied appearance. The length of the head measures 1.5mm and the height, 1.6mm. The myomeres could be separated into 7 abdominal and 23 caudals. Some of the anterior myomeres have developed a zigzag pattern. The processes of branchiostegal rays and gill arches are noticeable. The eyes also show proportional increase in size, having a diameter of 0.4mm. The mouth lacks teeth at this stage. The notochord is still straight. The pectorals show a certain degree of advancement in their growth. They measure 0.3mm in length and are very conspicuous. At this stage the larva might be capable of swimming fast. The dorsal parts of stomach and alimentary canal are well pigmented. The pigmentation in the gut region is confined to the peritoneal cavity. On the top of the head are noticed two small pigment spots. The stomach and intestine retain the same pattern of pigmentation. Posterior to the anal opening as many as eighteen pigment spots could be counted. In the caudal region one pigment spot is noticed at the base of the hyural plates and another at the distal margin of the caudal rays. The 5.3mm long larva is very deep bodied and short. In relation to the greater size of the head, the eyes also show a proportional increase in size (0.7mm in diameter). A lengthening of the intestine is also observed at this stage. The myomeres appear very compact and exhibit a high degree of zig zagging, indicating further advancement in the muscle differentiation towards the adult condition. Nine abdominal and twentyone caudal myomeres could be demarcated. Ossification of principal caudal rays is already noticed. The vertebral column and urostyle are almost completely ossified. The second dorsal, though appearing like a memberanous finfold, shows signs of ossification of rays especially at the positions of the basals. Even though the entire finfold uniformly, exhibits a thickened margin towards the base through out its length,

13 the future position of the second dorsal is clearly indicated. On close examination as many as 12 thickened basals and an equal number of very thin supporting rays could be noticed. Even though the first dorsal is not yet formed, its future site is demarcated by the thickening noticed just anterior to the second dorsal. The anal also is almost in the same stage of development as the second dorsal. It is located just opposite to the second dorsal, having about 12 thickenned basals. The dorsal and anal finlets are not developed at this stage The caudal has under gone a higher degree of ossification than the dorsal and anal up to 15 caudal rays could be counted. The tip of the urostyle is curved upwards. Of all the fins, the pectorals are the most conspicuous with a high degree of muscular support. The total length of the fin including the stalk measures. 6mm. Six teeth are noticed in the upper jaw and four in the lower. Gill rakers are better developed. Four branchiostegal rays are clearly visible. The dorsal side of the head and the tip of the snout are pigmented. Pigmentation is also seen all over the stomach, especially in the peritoneal cavity. Pigment spots present at he anterior and posterior margins of the anal opening as in the previous stages are noticed in this stage too, but they appear to be darker. Two other pigment spots are also noticed just below the stomach. The ventro lateral row of pigment spots start from the 13 th myomere is found to be unpigmented. On the caudal region three conspicuous pigment spots are present on the caudal fin also, of which two are below the hypurals and one towards the distal end of the fin rays. The melanophores on the occipital region and top of head form a more or less circular pattern. The number of ventral pigment spots is limited to14, and they exhibit some degree of fading. The post larval and early juvenile stages (Figs. 4-6 Balakrishnan and Rao) resemble the adult in general appearance, with the comparatively long head, deep body and big eyes. In the 8.7 mm stage, the eyes are completely pigmented, jaw with few teeth and pre-opercle umarmed. All fins except 1 st dorsal are well developed with full complements of rays. The first dorsal is low and has only 5 spines. There are 6 dorsal and anal finlets. Pectoral is fan shaped. Pelvic is small and thoracic in position. Finlets are interconnected by a membrane. Pigmentation is localized characteristically to the tip of the snout, mid brain region, sides of the body adjacent to the visceral cavity and the base of vertical fins. In addition there are chromatophores, one on the tip of the lower jaw, 2 on the forebrain, two to three on the hind-brain region and four on the operculum. Similarly 4 chromatophores in a row on the mid-lateral side of the caudal region and a single one in the middle of the fluke of caudal fin are present. The 11.4 mm post larva has 6 teeth on the upper and seven on the lower jaw. Six spines are discernible in the first dorsal. Further increase in the pigmentation on the tip of the snout, dorsal side of head and opercle is recognizable. Four chromatophores have developed on the upper jaw. A single chromatophores in the preorbital area and a row of four in the post orbital are present. Interspinous membrane of the first dorsal is pigmented. The deep bodied and chubby early post larvae assumes a fusiform shape and increases in the density and pattern of pigmentation especially on the dorsal half as it grows (Figs. 1-6). Ref.

27 Eggs and larvae: Ref. No.: Information on eggs is not available. Ripe ovum is reported to be of having a diameter of 0.97 mm with single oil globule of 0.2 mm size. Larva very closely resembles morphologically that of A. thazard, except for the comparatively slender body and small head. There are 5 opercular spines in the 3.7 mm stage larva. Myomeres are 39 in number. Pigmentation on the body is much less. 3.7 mm to 7.2 mm larva lack chromatophores along the midlateral line in the caudal region. The smallest specimen (3.5 mm) has a single dark pigment spot at the symphysis of the pectoral girdle, and chromatophores on the both dorsal and ventral edges of the body in the caudal peduncle region. A long series of well spaced chromatophores is present along the entire length of the ventral margin of the body. Midbrain is sparsely pigmented. In the 5.2 mm stage there are 3 very closely spaced chromatophores on the midventral line of the caudal peduncle, and 4 widely spaced chromatophores farther forward. In 7.2 mm stage first dorsal consists of 5 spines and second, 11 rays. Anal fin also shows signs of development (Figs. 1-7).

34 Eggs and larvae: Ref. No.: Eggs: Ripe ovum is large, spherical, transparent with oil globule and an average diameter of 1.3 mm when fresh and 1.04 mm on preservation. Larvae: No information is available on early larvae. Three larvae measuring 4.2 mm, 4.9 mm and 6.1 mm described by Gorbunova, 1974 (Figs. 1-3 ) are reproduced here to facilitate identification. These larvae are less pigmented with chromatophores on the forebrain, tip of snout, stomach and along the midventral line up to urostyle. In the first two staged fins are represented by only finfolds. Opercular spines are present, the fourth one being the longest. In the 6.1 mm stage larva the head is more elongated with pointed snout and prominent opercular spines. The jaws are with teeth. There are large pigments noticed on the lower jaw. Rudiments of dorsal and anal are already indicated. In 3.5 mm larva described by Klawe, 1961 (Fig.4) only 3 opercular spines are seen. Area of forebrain is pigmented. Posterior to the vent chromatophores are present along the midventral line up to the urostyle. In juveniles of about 80 mm length (Fig. 5) twelve transeverse bands which are incomplete ventrally are present over the body gradually change into characteristic wavy lines of the adult.

41 Eggs and larvae: Ref. No.: Fully ripe ovum is spherical and transparent having a mean diameter of 0.9mm and with an oil globule of about 0.14mm size. Early larvae has a large head in comparison with the body, which is long and slender. Greatest depth is posterior to the eye. The abdominal sac is characteristically small and is situated anteriorly to the mid-point of total length. The mouth is large and the angle of jaws reaches to about a vertical below the posterior margin of the eye. The lower jaw is slightly included at the tip. Diameter of eye is less than the length of the snout which is long and pointed. A maximum of 8 spines are developed normally along the edge of the preoperculum, the one in the preopercular angle being the longest. Number of spines varies with the size of larvae, the maximum number being present at about 8mm stage. These spines gradually get atrophied in juvenile stages. Rudiment of dorsal fin begins to develop, when the larvae reach a length of about 6.7mm. In juveniles 20 precaudal and 21 caudal vertebrae could be counted. The presence of a single chromatophore, a little anterior to the caudal peduncle along the midventral line is very characteristic of this species, and this persists even at a very later stage. Chromatophores begin to develop on the opercle in the specimens of about 5mm and more. Early appearance of chromatophores over the forebrain in specimens of more than 7mm length, the presence of chromatophores on the middle of each mandible, and formation of few chromatophores along the anterior portion of the first dorsal fin are very characteristic. Dermal chromatophores are present at the tip of lower and upper jaws.

47 Eggs and larvae: Ref.No.: Ripe ovum is reported to be between 0.76 mm and 1.23 mm in diameter, with a golden yellow oil globule of 0.26 mm size. The larvae differ from other tuna larvae by the absence of chromatophores over the forebrain and midventral line near caudal peduncle, early development of dorsal spine and heavy pigmentation of the first dorsal in specimens over 7mm length. In specimens of about 5 mm, the dorsal outline tapers from the region of the head to the end of the tail. The ventral outline is rounded in the abdominal region and tapers gradually to the end of caudal. Snout is pointed and diameter of eye is less than the length of snout. The first dorsal develops comparatively early and rudiments of spines are visible even in specimens of 6 mm length. Seven preopercular spines are visible in specimens of about 7.5 mm and one at the angle is the longest. In 8 mm stage, the dorsal contour is deep, mouth is large and oblique, and the maxillary almost reaches a vertical below the posterior margin of the pupil. Chromatophores are present over the midbrain, along the hindbrain aspect, a few on the sides of the head near the dorsal end of the preopercle and posteroventral boarder of the eye. Body is unpigmented until the larva reaches a length of about 12 mm excepting for the dorsal region of the abdominal sac, which bears internally numerous chromatophores. The dorsal is heavily pigmented in specimens of more than 7 mm length. When the larva approaches 11 mm length, the body becomes much deeper, the abdominal sac is large and elongates, and the vent is posterior to the mid point of the total length. In general, it attains juvenile features early, eventhough preopercular spines persist and the chromatophores not formed at the body (Figs 1-6).

53 Eggs and larvae: Ref. No.: Information on eggs is not available. Ripe ovum is reported to be of having an average diameter of 0.99 mm with single oil globule of 0.25 mm. Larval stages are characteristically long and slender and head conspicuously large. The abdominal sac is triangular, small and anteriorly situated. The vent is far forward of the mid point of total length. Eye diameter is more than the length of snout in early stages. Seven preopercular spines could be distinguished. There are 39 myomeres, of which 20 are precaudal and 19 caudal. Teeth are present on both jaws. Pigments are present on the membrane covering the brain and the sides of the head. An important distinguishing character is the presence of an irregular row of dark chromatophores along the posterior portion of the ventral midline, and a series of 4 or 5 chromatophores in anterior half of the mandible.
